The fine chemical products whose raw materials are methanol and dimethyl ether

The cost of using methanol carbonylation is l / 3 of traditional esterification. The methyl demand will be increased by l0% year by year. With the continuous improvement of environmental requirements, fine chemicals methyl formate process of methanol, carbon dioxide and hydrogen synthesis is worthy of attention.

Methylamine is currently the world annual production capacity of LL2 million t annual production capacity of 250,000 tons, the annual global consumption of l65 million t, increasing annual consumption rate of l2%. With the rapid development of China dimethylformamide, has also led to methylamine, in particular the increasing demand of dimethylamine. Belgium the methylamine developed manufacturing processes to methanol and ammonia as raw materials, through the development of high-performance catalysts can be prepared to take any percentage of a methylamine, dimethylamine and trimethylamine, is all automatically controlled continuous production process, the process The total yield was 96.5%, high purity of the product, the catalyst life for more than two years. Fine chemicals products dimethyl carbonate vapor phase oxidative carbonylation synthesis of dimethyl carbonate (DMC) owns widespread concern on environmental issues in recent years.

Dimethyl ether at room temperature and atmospheric pressure is a colorless, flammable gases, non-corrosive, non-toxic, soluble in water, ethanol, ether, acetone, chloroform and other solvents, flame burning high brightness. Dimethyl ether unique physical and chemical properties of the cornerstone of its basic industries in the international market position can be widely used in industry, agriculture, medical care, daily life and other fine chemical industry. Dimethyl ether is mainly used for alternative vehicle fuel, liquefied petroleum gas, city gas, but also as aerosol propellants, refrigerants, foaming agents, etc., the market prospect is extremely broad, fine chemical industry of the international development priorities.

The main producing countries of dimethyl ether are the United States, Germany, Britain, France and so on. The world's annual production of dimethyl ether has more than 20 million tons; dimethyl ether production is over 20,000t. There is 80% of the production of dimethyl ether used in the production of aerosol. Only an aerosol, the dimethyl ether of the world's annual demand of 3.75 million tons, China's annual demand for 80,000 tons, and annual increment rate of 5% to 8%. The use of dimethyl ether in aerosol propellants, refrigerants and blowing agents are only a small part of its functions. Its main function is becoming an alternative for vehicle fuel, liquefied petroleum gas used in city gas, is the solution to Chinese triphenyl bismuth energy, economic, and environmental protection, adhere to the sustainable development of the key.

Dimethyl ether as a motor fuel substitute for diesel fuel is currently the main areas of industrial applications of dimethyl ether. As we all know, the engine thermal efficiency than gasoline engines from 7 to 9 percentage points, but the existing diesel engine pollution is gradually phased out, dimethyl ether diesel fuel efficiency, environmental protection, etc. are gradually replacing the original diesel. The diesel is the largest amount of China's oil, but also the gap's largest oil and diesel accounted for the first three oil. Chinese diesel demand of 70 million tons in 2000 to reach 108 million tons in 2010. Dimethyl ether to replace diesel as fuel for vehicles, is the urgent needs of the energy development of the times, but also the inevitable result of its market demand can be imagined.

Dimethyl ether as one kind of fine chemicals products and domestic fuel, comparing to liquefy petroleum gas, it has higher safety performance and integrating heat value. It doesn’t absorb the carbon residue. It can be mixed and burning with liquefied petroleum gas. It makes the liquefied petroleum gas residue burning. Many advantages of dimethyl ether make the foundation for it replaces liquefied petroleum gas.Source:http://www.mhcfm.com
