Driven by national policies, the carbon tetrachloride industry will gradually develop in the direction of environmental protection

Carbon tetrachloride, also known as tetrachloromethane, is an organic compound with the chemical formula CCl4. Carbon tetrachloride appears as a colorless and transparent liquid with a slightly sweet smell. It is miscible in ether, petroleum ether, chloroform and ethanol, and is insoluble in water. Carbon tetrachloride is chemically stable, volatile, and non-flammable, and is widely used in spices, pesticides, fire extinguishing agents, dry cleaning agents, refrigerants and other products. According to different uses, carbon tetrachloride can be divided into carbon tetrachloride for reagents and carbon tetrachloride for auxiliaries.

The preparation methods of carbon tetrachloride include methane oxychlorination, carbon disulfide, phosgene catalysis and methane thermal chlorination. The carbon disulfide method refers to the phase reaction of carbon disulfide and chlorine gas under the action of an iron catalyst, and finally produces carbon tetrachloride after neutralization, distillation and other steps; the methane thermal chlorination method refers to mixing chlorine gas and methane under high temperature conditions , and then through steps such as neutralization, drying, and distillation, carbon tetrachloride is obtained. At present, the carbon disulfide method and the methane thermal chlorination method are the mainstream preparation methods of carbon tetrachloride in my country.

According to the “2023-2027 Carbon Tetrachloride Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, The main raw materials of carbon tetrachloride are methane and chlorine. Chlorine has strong oxidizing properties and is widely used in many environmental protection and chemical industries. In recent years, my country’s chlorine production has maintained a steady growth trend. Benefiting from the sufficient supply of raw materials and continuous breakthroughs in production technology, the development of my country’s carbon tetrachloride industry has accelerated. However, currently, due to the impact of environmental protection policies, my country’s carbon tetrachloride production needs to be approved by the Ministry of Ecology and Environment. According to statistics from the Ministry of Ecology and Environment, my country’s carbon tetrachloride usage quota will reach 330 tons in 2021.

Carbon tetrachloride has a wide range of uses, but it can easily cause environmental pollution, and the country attaches great importance to this. The “Guidance Catalog for Industrial Structural Adjustment (2019 Edition)” issued by the National Development and Reform Commission will be implemented on January 1, 2020. The document clearly stipulates that by-products of chemical products such as carbon tetrachloride must be comprehensively utilized. Against this background, my country’s carbon tetrachloride industry will gradually develop in a green and environmentally friendly direction.

Su Qiangsheng Functional Chemical Co., Ltd., Lianlongbohua (Tianjin) Pharmaceutical Chemical Co., Ltd., PetroChina Co., Ltd., Xilong Science Co., Ltd., etc. are the main participants in my country’s carbon tetrachloride market. PetroChina occupies the entire usage quota of carbon tetrachloride for additives in my country and ranks as the industry leader.

Industry analysts said that carbon tetrachloride, as an organic compound, has been widely used in many fields. Driven by market demand, , the industry development space continues to expand. After years of development, my country’s carbon tetrachloride preparation technology has matured. Driven by national environmental protection policies, the industry will gradually develop in a green and environmentally friendly direction. It is expected that the development trend of my country’s carbon tetrachloride industry will continue to improve in the future.
