What
is Chemistry?
Chemistry is what
happens whenever sunlight hits the leaf of a tree, beginning the process
of photosynthesis. Chemistry is what takes place when our brain is processing
millions of pieces of information to command our movements, emotions and
actions.
Chemistry is present in all living things. The human body, for example, is like a large chemical plant where chemical reactions take place every second, keeping the human being alive. Without chemistry, there is no life.
Man started studying chemical phenomena centuries ago. Alchemists looked for ways to achieve the transmutation of metals, while others searched for the elixir of long life. No matter what their objectives may had been, the fact is that by mixing plant extracts with substances taken from animals, our first chemists were also trying to find ways to cure diseases, or at least relieve the pain suffered by poor mortals. Through their experiments, they created a science that is constantly expanding mankind's horizons. As time went by, new products, new applications and new substances were discovered. Man started learning how to synthesize Nature's elements; develop new molecules; and alter the composition of matter. The importance of chemistry never stopped growing and today it plays such a relevant role in our day-to-day lives that we no longer distinguish what is and what is not chemistry.
What we do know, however, is that without chemistry civilization would never have reached its current scientific and technological level that permits man to explore the frontiers of the universe; to travel at the speed of sound; produce food in the middle of the desert; produce potable water from the oceans; develop medicine for diseases that were previously considered incurable; and multiply the number of goods and products, which before were accessible to only a privileged few. And why did all this take place? Because CHEMISTRY IS LIFE.
CHEMISTRY: A SCIENCE THAT IS ALWAYS PRESENT.
Chemistry is
of fundamental importance to any country's economic and technological
development. From steel making to the computer industry; from the arts
to civil construction; and from agriculture to the aerospace industry,
there is not one single area or sector that does not include some chemical
input in its processes or products. With a high degree of scientific and
technological development, the chemical industry transforms nature's elements
into products that are useful to man. Through advanced processes, substances
are altered and re-mixed to create the raw materials used in the production
of medicines; in the generation of energy; the production of food; the
purification of water; the manufacturing of goods such as automobiles
and computers; the building of homes; and the production of a wide range
of other items like the clothes, household appliances and personal hygiene
products that are present in our modern day-to-day lives.
THE
CHEMISTRY OF PURE WATER.
Water is our
planet's most abundant element. Although it covers three quarters of the
earth's surface, only a small portion of it - located near urban centers
- is potable. Without chemistry, it would be impossible to guarantee a
steady supply of drinking water. Chemistry is what changes water that
is improper for human consumption into pure, crystalline, contaminant-free
water. Chlorine dioxide, for example, is used to oxidize organic matter
and destroy microorganisms. Iron chloride and aluminum sulfate absorb
and precipitate dirty matter in suspension. They also eliminate color,
taste and odors. Active carbon retains micro-pollutants and detergents.
Soda and lime neutralize the water's acidity. It is the chemical industry
that supplies these and other products that allow man to continue enjoying
pure and healthy water - an element that is essential to life.
CHEMISTRY
THAT FEEDS.
How can a constantly
growing population be fed without exhausting natural resources? The answer
is chemistry. Chemical products fertilize the soil and conserve and increase
its production potential. The renewal of elements such as nitrogen, phosphate,
potassium and calcium - carried away by rain and wind, destroyed by fire
and depleted by constant harvesting - is fundamental for the maintenance
of the soil's productivity. Without chemical fertilizers, areas that have
been depleted or are unsuitable for farming would have to be abandoned,
resulting in a drop in food production. Without chemical fertilizers forest
reserves would dwindle as new agricultural areas are opened. Fertilizers
help guarantee the quality of the food produced by farmers, the productivity
of the land and prevent the spread of disease. As for cattle raising,
veterinary medicines preserve the health of the herds, prevent epidemics
and increase productivity. As we can see, chemistry offers a wealth of
solutions that help man eliminate the specter of hunger.]
THE
CHEMISTRY OF HEALTH.
Without chemistry,
which is present in practically all medicines, scientists would not be
able to synthesize new molecules that cure diseases and strengthen the
health of human beings. But, the use of chemistry transcends medicine
for its prolongs and protects man's life. The chemical sector, which supplies
other industries with a fantastic amount of basic products, also develops
raw materials specifically for the medical field. Heart valves, artificial
limbs, disposable syringes, surgical gloves, serum recipients, flexible
and atoxic tubes and bags for the collection and storing of blood are
just a few examples of the kind of products made possible by chemistry
and which have revolutionized the world of medicine. Chemistry plays an
important role in hospitals, clinics, and intensive care unit. The modern
equipment used in surgeries and to diagnose illness is manufactured with
chemical raw materials. Infections are fought and controlled with advanced
disinfectants. Reagents accelerate the results of lab exams. The concept
that chemistry is life is more evident in medicine than in any other field
of activity.
CHEMISTRY IN OUR DAY-TO-DAY LIVES.
Chemistry is
with us 24 hours a day. It is present in just about every single product
that we use in our day-to-day lives. From the sophisticated computer to
the simple ballpoint pen and from the impressive automobile to the small
toy car, there is not one product that is not made with raw materials
supplied by the chemical industry. Plastic resins are used to mold the
keyboards, cabinets and diskettes of computers. The automobile contains
an enormous list of chemical-based products such as: the steering wheel,
panel, lining and upholstery, seats, electrical wires covered in plastic
insulators, hoses, fuel tanks, fenders and tires. Chemical-based packaging
protects most food products. Chemistry produced the synthetic fibers and
dyes of our clothes. There is an infinity of products in our homes, which
directly or indirectly are the result of the chemistry: the paint that
covers our walls, plastic toys and pots, tubes used to carry electricity
and water, rugs, carpets and curtains. And let's not forget the chemical
components found in our washing machines and dishwashers, refrigerators,
microwave ovens, videogames and television sets. Chemistry is also present
in the personal hygiene and housecleaning products that we use. It's just
a matter of paying attention. Without chemistry, our day-to-day lives
would be much more difficult. To help man lead a healthier and a more
comfortable and secure life with more time for leisure, the chemical industry
is constantly investing in technology, safe processes and in the development
of new products. The result is progress.
THE CHEMISTRY OF NEW MATERIALS.
Petrochemistry
is one of the chemical industry's most important fields of activity. Starting
with ethylene - obtained from the naphtha of petroleum, or directly from
natural gas - petrochemistry creates a series of raw materials that allow
man to produce materials that replace wood, animal skins and other natural
products. Two such products are plastic and synthetic fibers. The principal
thermoplastic resins are: high-density polyethylene (HDP), low density
polyethylene (LDP), polyethylene terephthalate (PET), polypropylene (PP)
, polystyrene (PS), polyvinyl chloride (PVC), and ethylene vinyl acetate
(EVA). These resins are used to make auto parts, computer components and
by the aerospace and electric/electronic industries. They are also used
to manufacture bottles, footwear, toys thermal and acoustic insulators,
and such a wide variety of other products that it is hard to imagine today's
world without plastic resins. The products made by the petrochemical complexes
are also used to produce, among other things, ethylene glycol, terephthalic
acid, dimethyl terephthalate, and acrylonitrile - raw materials used in
the production of polyester, nylon, acrylic and other fibers and threads.
Synthetic fibers, blended or not with natural like fibers cotton and wool,
are transformed into textile goods and other products used by different
industries, like tire manufacturers, for example. New uses for synthetic
fibers and thermoplastic resins emerge every day. The result is greater
production, lower prices, easier access to consumer goods and a better
quality of life.
CHEMISTRY
DESIGNS THE FUTURE.
Vehicles that
are totally recyclable, built with more resistant materials which are
lighter than steel. Safe and comfortable homes that are built quickly
and at a low cost. Degradable products that help recover the soil's fertility.
Vegetable plantations that produce plastics. High energy and non-polluting
fuels. More efficient medicines. Substances capable of making an entire
city's sewage output become inert. The recovery of areas devastated by
centuries of exploitation. Dreams? Not for chemistry, a science that is
constantly expanding the frontiers of knowledge. With an eye on the future,
the chemical industry invests a large part of its revenue in research
and development. The chemical industry's synthetic fibers allowed the
textile sector to enlarge its production and reduce prices. Plastics were
used to create packaging that preserves food and medicines for long periods
of time. They are also used to produce rust-free tubes and parts and components
for all kinds of different industries. These are just a few examples.
The chemical industry will help man develop the processes and materials
that will guarantee food, housing and comfort to future generations. Much
of the future that lies in store for man and the Planet is now being designed
by chemistry.
THE CONTINUOUS IMPROVEMENT OF CHEMISTRY.
One of the most
important worldwide concerns is to avoid or prevent the environmental
impact of human activities. Like in many other activities, the manufacture
of chemical products involves risks. But the chemical industry, which
for years was considered a villain, an aggressor of nature, has invested
heavily in control equipment, in new management systems and technological
processes to reduce to a minimum the danger of ecological accidents. An
example of this is the Responsible Care Program, which in Brazil is coordinated
by ABIQUIM - the Brazilian Chemical Industry Association. The Responsible
Care Program establishes procedures for the continuous improvement in
several of the industry's fields of activity. In this respect we should
underscore the following areas: reduction of effluent emissions, control
of residues, employee health and safety and emergency readiness. The entire
life cycle of a chemical product is thoroughly analyzed to avoid any risk
to the environment, even when the consumer throws away the packaging.
Effluents and residues and treated until they become inert. Several companies
are using sophisticated environmental control equipment. Teams are being
constantly trained to act swiftly in the event of accidents with chemical
products, thus avoiding risks to man and the environment. The chemical
industry works, invests and researches in order to play clean with Nature
in a game everyone wins.
