An Introduction to “Green chemistry”

Humans are facing the unprecedented environmental crises nowadays, which are caused by the increased population, the higher consumption of source, the reduction of per capita amount of land, water and mineral products. The contradiction between population and resource become shaper and sharper. The environmental protection turns out to be one of the most important issues of economy and social development.

The developing of industrialization provides people many new materials, and improves their substantial lives, however, it also brings so many wastes that degenerate the environment. In order to keep the level of people’s lives and to protect the environment, the new material which is nonpoisonous and harmless must be found.

Chemical industry and other related industry, being one of the pillar cornerstone industries in national economy, contribute much to the creation of human’s material civilization, meanwhile, discharging large numbers of harmful substances. Chemical industry also brings certain detriment to human health and environment.

Atom economy is the main characteristics of “Green chemistry”, that is to make full use of every atom to achieve no mission , therefore, “Green chemistry” can fully utilize the sources and make pollution free. The convert from traditional chemistry to “Green chemistry” can be defined the transformation from extensive mode to intensive mode. “Green chemistry” is able to make the wastes useful, increasing the economic benefits greatly. “Green chemistry” has been raised all around the world, which means a rare chance to the developing country like China. The related chemical products is degreasing agent
