Development history of methane chloride

1847, Fraser first produced chloroform for anesthesia in small quantities by acetone bleaching. In 1893, Miao Lei and du bois proposed to produce carbon tetrachloride by liquid phase chlorination of carbon disulfide. 1923 German Hearst Company produces dichloromethane by direct chlorination of methane. It was not until 1937 that the unit of Dow Chemical Company of the United States was put into production that the methane chlorination process was widely adopted and became the main route to produce methyl chloride. Methyl chloride can also be produced from methanol, which played an important role in the late 1960s.

In the series of methane chloride products, methyl chloride is the raw material of methyl chlorosilane, more than 85% of which is produced in silicone (basically self-produced), and the amount sold as a commodity is very small; According to the requirements of the Montreal Protocol on Substances that Deplete the Ozone Layer (hereinafter referred to as the Montreal Protocol), developed countries have shut down carbon tetrachloride factories (the by-products of carbon tetrachloride from dichloromethane and chloroform factories are sold to third world countries, and the rest are converted into other products to be digested as raw materials); Chloroform is mainly used as raw material for producing HCFC- 22 and polytetrafluoroethylene, and the raw material of HCFC-22 is increasing year by year. Dichloromethane is mainly used to produce paint remover, adhesive solvent, insecticide and aerosol.

At present, the global supply and demand of methane chloride are basically balanced, but its future output will vary from region to region due to the uneven development between products and countries and regions. The consumption of developed industrial countries and regions such as the United States will decrease year by year. However, the market demand for methane chloride in other countries and regions in the world, such as Eastern Europe, Asia, Latin America and other developing countries, will maintain a relatively fast growth rate.

China is a developing country. Except for carbon tetrachloride, the market of other methane chloride products has been in a period of rapid growth in recent years and has now developed to a certain scale.

Investigation Report on Methane Chloride Industry expounds the present situation, competition pattern, technical level, upstream and downstream connection, import and export, project investment, relevant policies and regulations, etc. On this basis, the future market structure and market prospect are analyzed and predicted qualitatively and quantitatively.
