As we all know, organic chemistry in particular
organic synthetic chemistry is developing a more complete discipline.
In the history of human civilization, improve its quality of life of
mankind made a huge contribution. However, it is undeniable that the
"traditional" methods of chemical synthesis and established according
to the "tradition" of the chemical industry, on the whole of mankind's
survival of the ecological environment caused serious pollution and
destruction. The past to solve the problem is the primary means of
governance, production, or even shut down, people for controlling
environmental pollution spend a lot of manpower, material and financial
resources. The early 1990s, chemists made with the traditional
"pollution treatment" different "green chemistry" concept, that is, how
to decrease from the source, or even eliminate the pollution generated.
Through research and improve the chemical process and the corresponding
technology, and fundamentally reduce and eliminate by-products or waste
generated, to achieve the protection and improvement of the
environment. "Green chemistry" of the goal and requirements of any
chemical activities, including the use of chemical raw materials,
chemical and chemical process and the final grain production, human
health and the environment should be friendly. Thus, the results of
research on green chemistry to solve environmental problems is of
fundamental significance. For the environment and the sustainable
development of chemical production also has important significance.
More than 10 years ago, on the concept of green chemistry, objectives,
principles and basic research fields, and so has to move clearly, the
initial formation of a multidisciplinary pay * the new field of study.
Specifically, the basic principles of green chemistry can include the
following: a) to prevent the pollution generated superior to the
pollution control; 2) atom economy; 3) as long as possible, should try
to use the toxic chemical synthesis on the line: 4) more secure
chemical crystal design should be able to retain their effectiveness,
but lower toxicity; 5) should do everything possible to avoid the use
of auxiliary materials (such as solvents, separation etc.), such as
when a drug-free; 6) should be considered To energy consumption on the
environment and economic impact, and should be minimal use of energy;
7) should be renewable raw materials, rather than be depleted; Cool to
avoid unnecessary derivative of the steps 9) catalytic reagents ( Have
the best possible optional) is better than equivalent of the reagent,
10) chemical products after the completion of its mission and should
not be Residues in the environment, and should be able to sound
degradation of the material: 11) analysis methods must be further
developed to The formation of harmful substances in the former to carry
out immediate and on-line tracking and control: 12) in the chemical
conversion process, the chosen material and substances should be able
to form as much as possible to reduce the possibility of a chemical
