The development of the green chemical process LiDanFu 10040343 class Abstract: with the continuous development of science and technology and economy, the green chemical process technology is also constantly by people use. This is just a probably of greening, including the development of green chemical, principles, and the sustainable development of the contact and the problems existing in the development of. Key words: green chemical industry development the principles of sustainable development 1The basic meaning of the green chemical process Green Chemistry is the English name: Green upon, the Green Chemistry is also known as: Environmentally Friendly chemical (Environmentally Benign upon), on the basis of the development of Technology has the following kinds: Environmentally Friendly Technology (Environmentally image Technology), Green Technology (Green Technology) or Clean Technology (Clean Tech - nology). The core of the green chemical process is to use chemical principle from the source to eliminate chemical industry pollution to the environment, green chemical process is the ideal of the atomic Economy (Atom Economy) reaction, that is to say every atoms are transformed into products of raw materials, so as to realize no waste and by-products of society, and realizing the zero discharge of waste; At the same time, not the use of poisonous and harmful materials, catalysts and solvents, and production of environmentally friendly products. Special need that is: green chemistry and the concept of green chemistry, using green chemistry is to emphasize green chemistry and The relationship between the workers . computer technology, is a clear the needs of society, and the scientific goal of new type of cross subject. From the scientific point of view: it is the updating and development of traditional chemical way of thinking; And if from an environmental point of view: it is from the source to eliminate pollution; If, then, from the economic point of view: it is a comprehensive utilization of resources, reduce the production cost, accord with economic conditions, and accord with the requirement of the sustainable development, is a major, advanced technology and scientific research. 2 green chemical industry leading chemical process development 2.1 the atom economy At present, the biggest challenge of all chemical industry is one of energy saving and emission reduction. People through constant reflection and summary of chemistry and the relationship between the environment and resources, and advances some countermeasures for atom economy in the new (1991, Stanford university, a doctor professor atom economy concept). Atom economy international energy from renewable raw materials and production of the product demand is growing. 2.3 green chemical industry Is the most widely recognized definition of green chemistry to reduce or eliminate the risk of substance use and the design of chemical pareness of environmental protection is the root cause of the serious problem, but now China is vigorously promoting the strategic thought of sustainable development, people must be thoughtful in chemical production, especially the problem of engineering technology, to promote green chemical concept of production. Today, to create economical of economy and society, so for the cost of the pollution caused by waste is to strictly prevent, country before chemical production should be the premise of the economic environment for the development of construction, and attach importance to the chemical pollution. The traditional chemical pollution treatment means - end though can improve the environment quality, but it is index not effect a permanent cure, and the cost is higher, if you want to completely improve the ease of chemical pollution, or from the chemical production process, on the improvement of the green chemical industry. improve chemical pollution, environmental protection but also economy. Whether it is the efficient utilization of materials or reasonable treatment of waste, green chemical has incomparable advantages. The promotion of green chemical industry is the important measure to realize economic way change, at the same time, the energy conservation and emission reduction and sustainable development have better security, and promote the development of social economy and natural environment harmonious good. 4 the problems of the green chemical technology and development By using the method of the sustainable development of green chemistry, and to reduce maintenance needed for the human life level and the progress of science and technology of chemical products and processes used to produce the harmful substances as a target, and the related chemical activities of all belong to the category of green chemistry. From social, technical, economic, environmental, political, and forces, according to the better Faraday association in 2004, the roadmap of the eight technology, namely, the green product design, raw materials, reaction, catalyst, solvent, process improvement, separation technology and realization technology. 5 conclusion Green chemistry has been widely recognised as the 21 st century one of the most important fields of science, is the realization of pollution prevention is the most basic means of science. Although it is difficult to make a precise and comprehensive in its future development trend forecast, but according to the research progress of can now conclude that the development of environmental protection and low emissions of chemical production process to realize the energy saving and emission reduction and environmental protection, and green chemistry in some specific research area has scientific resear
