The status of chemical industry in the national economy:
The development of chemical industry plays a great role in the improvement of industrial production process (such as replacing heavy mechanical process with chemical process), the development of agricultural production, the expansion of industrial raw materials, the consolidation of national defense, the development of cutting-edge scientific and technological development, the improvement of people's life as well as the development of the comprehensive utilization of the economy, which is an important part of the national economy.
The history and current situation of China's chemical industry before 1949, China's chemical industry is very weak, only in Shanghai, Nanjing, Tianjin, Qingdao, Dalian and other coastal cities, there are a small number of chemical factories and some handmade workshops. Only a few sulfuric acid, soda ash, fertilizers, rubber products and pharmaceutical preparations could be produced, and there was basically no organic chemical industry.
After the establishment of the People's Republic of China, the chemical industry has been developing rapidly, and has gradually formed a relatively complete range of chemical minerals, chemical fertilizers, acids, alkalis, inorganic salts, synthetic rubber, synthetic fibers, synthetic resins and plastics, organic raw materials, pesticides, dyestuffs, paints, photographic materials, rubber products, solvents, auxiliaries, and chemical reagents, catalysts, and other categories of the industry.
Currently, the natural and technological sciences of the various disciplines are brewing new technological breakthroughs, the chemical industry will also be catalyzed, molecular design, lasers and chemical bionics and other major technological breakthroughs and enter a new era.
The role of the chemical industry in the national economy:
The chemical industry plays an increasingly important role in the production of the national economy and people's social life. Specialty chemicals are both chemical products, and chemical products in the emerging development of high-tech products,. Since entering the new century, China's specialty chemicals industry is accelerating the development trend, and has made gratifying achievements.
January to November 2008, China's specialty chemicals industry to achieve a cumulative total industrial output value of 709,369,381 thousand yuan, an increase of 31.81% over the same period last year; to achieve a cumulative sales revenue of 676,740,338 thousand yuan, an increase of 29.90% over the same period last year; to achieve a cumulative total profit of 40,968,874 thousand yuan, an increase of 15.51% over the same period last year. It was 15.51% higher than the same period of the previous year.
In January-November 2009, China's special chemical products manufacturing industry realized main business income of 820,964,109,000 yuan, an increase of 16.16% over the same period of the previous year; total accumulated profits of 52,558,688,000 yuan, an increase of 22.04% over the same period of the previous year.
At this stage, China's specialty chemicals industry enterprises must seize the new development situation, increase scientific and technological innovation, realize the structural adjustment of the chemical industry, learn from foreign advanced experience, strengthen independent research and development ability, develop advantageous industries and advantageous products, and realize sustainable development.

Characteristics of the chemical industry:
The chemical industry is a knowledge- and capital-intensive industry. With the development of science and technology, it is from the initial production of soda ash, sulfuric acid and a few other inorganic products and mainly from plants to extract alizarin made of dyes and organic products, and gradually developed into a multi-industry, multi-species production sector, the emergence of a large number of comprehensive utilization of resources and large-scale chemical enterprises.
These enterprises on its production process, with other industrial enterprises have many **** sex, but on the production process technology, the comprehensive utilization of resources and the production process of strict proportionality, continuity and so on, and has its own characteristics:?
1, production technology with diversity, complexity and integration. Chemical product variety, the production of each product requires not only one to several specific technologies, and a variety of sources of raw materials, processes are also different;
It is the production of the same chemical product, there are a variety of sources of raw materials and a variety of processes. Due to the diversity and complexity of chemical production technology, any large-scale chemical enterprise production process to be able to carry out normally, there is a need to have a variety of technology synthesis.
2, with the comprehensive utilization of raw materials. Chemical industry production is a chemical reaction, in the mass production of a product at the same time, often produce many co-products and by-products, and most of these co-products and by-products and the chemical industry is an important raw material, can be reprocessed and deep processing. Therefore, the chemical sector is the most capable of opening up raw materials from the material, the comprehensive utilization of material resources of a sector.
3, the production process requires strict proportionality and continuity. General production of chemical products, a variety of materials have a certain proportion of requirements, in the production process, between the upper and lower processes, workshops, sections, often need to have a strict ratio, otherwise, not only will affect the yield, resulting in waste, and may even interrupt production.
Chemical production is mainly a device production, from raw materials to product processing of all aspects of the pipeline are transported to take automatic control to regulate the formation of a first and last coherent, each link closely linked production system. Such a production device, objectively requires the production of long-cycle operation, continuous. Failure of any part of the production process may be interrupted.
4, chemical production also has the characteristics of high energy consumption. Because, first, coal, oil, natural gas is both the fuel power of chemical production, but also an important raw material; Second, the production of some chemical products, need to be carried out in high or low temperature conditions, whether high or low temperature need to consume a lot of energy.
Chemical production of this series of characteristics that, in the management of chemical enterprises, we must pay attention to the role of technology in production, improve the level of technology; cherish the chemical resources, and make good use of the comprehensive utilization; pay attention to energy conservation; improve the organization of production, to maintain the long-term operation of the production, and constantly improve economic efficiency.
