my country’s methylene chloride industry chain has been basically perfected and output is gradually declining

The chemical formula of dichloromethane is CH2Cl2. It appears as a colorless and transparent liquid under normal temperature and pressure, accompanied by a pungent odor similar to ether. It is soluble in ethanol and ether. Dichloromethane is one of the non-flammable low-boiling point solvents. When heated to form high-concentration vapor, a weak mixed gas is produced. It has the characteristics of low toxicity and strong solubility. After years of development, the preparation methods of methylene chloride have become increasingly mature, and can be roughly divided into natural gas chlorination methods, methyl chloride chlorination methods, etc. Among them, the methyl chloride chlorination method has become a mainstream method of industrial production due to its high production efficiency.

At this stage, my country’s methylene chloride industry chain has been basically completed. The upstream of the industrial chain is mainly the raw material industry, providing chlorine, natural gas, methane, methyl chloride and other raw materials; the midstream is mainly the production industry of methylene chloride, responsible for the extraction and processing of methylene chloride; the downstream is mainly oriented to application fields, mostly used for making Products such as metal cleaners, metal degreasers, paint removers, polyurethane foaming agents, extracts, refrigerants, aerosol propellants, etc. are widely used in household appliances, medicine, film, polycarbonate and other fields.

In recent years, my country’s economic level has gradually improved, residents’ consumption structure has gradually upgraded, and the market penetration rate of refrigerators, air conditioners and other home appliances has gradually increased. Refrigerant is an important component of refrigeration appliances such as refrigerators and air conditioners, and the market demand is gradually growing. Against this background, my country’s refrigerant market capacity has gradually increased. In 2022, China’s refrigerant market capacity will be 541 million yuan, a year-on-year increase of 6.32%. As the main raw material for the production of refrigerants, methylene chloride’s market has been affected to a certain extent.

According to the “China’s Dichloromethane Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028” released by the Industrial Research Center, As my country’s methylene chloride production technology gradually advances, product performance gradually improves, application fields gradually expand, and market demand gradually grows. Due to the high degree of environmental pollution caused by the methylene chloride production process, it is easy to cause destructive effects on the ecological environment. With the gradual implementation of my country’s environmental protection policies, the production capacity of methylene chloride production enterprises has been affected to a certain extent. And affected by the epidemic, the operating rate of my country’s methylene chloride enterprises has gradually declined, resulting in a gradual decline in methylene chloride production. In 2022, my country’s methylene chloride production will be 1.9597 million tons, a year-on-year increase of 5.23%.

Industry analysts said that there are a large number of methylene chloride companies in my country and the market concentration is low. The largest methylene chloride companies in my country mainly include Longshun Chemical, Longbang New Materials, Honghe Chemical, Luxi Chemical, Tiannuo Trading, Mingju Chemical, Dongyue Group, Juhua Co., Ltd., etc. In addition, there are a large number of small and medium-sized enterprises in my country’s methylene chloride market. The products produced by these enterprises are highly homogeneous, with single product types and weak market competitiveness. As my country’s methylene chloride market continues to develop, market competition is fierce. Large enterprises continue to upgrade and expand their industrial scale. The living space of small and medium-sized enterprises is gradually squeezed and may be eliminated in the future. Market concentration is expected to increase.
