my country’s propylene oxide production capacity is gradually increasing, with Shandong Province accounting for the largest share of production capacity

Propylene oxide (PO), also known as methylethylene oxide, 1,2-propylene oxide, etc., is a very important organic compound. The chemical formula of propylene oxide is C3H6O. It appears as a colorless, transparent, flammable liquid with an ether smell under normal temperature and pressure. It is miscible with ethanol, ether and other solutions. Propylene oxide has a certain degree of toxicity and is highly irritating to human mucous membranes and skin. In severe cases, it can damage the human conjunctiva and cornea, and cause skin burns and swelling.

At present, my country’s propylene oxide preparation technology has been basically mature, and can be roughly divided into chlorohydrin method (CHPO), co-oxidation method, direct oxidation method (HPPO), etc. Among them, the chlorohydrin method will cause a lot of pollution during the production process and has been restricted in production; the co-oxidation method will also have some limitations in the future due to harsh reaction conditions and complex production processes; the direct oxidation method has mild reaction conditions and is green and environmentally friendly. , lower cost and other advantages, but our country has not yet achieved a technological breakthrough, and it may become the mainstream process in the industry in the future.

Propylene oxide is mostly used to produce propylene glycol methyl ether, polyether polyol, propylene glycol ether, dimethyl carbonate and other products, and is widely used in pesticides, organic synthesis, chemical industry, daily chemicals, textiles and other industries. Among them, polyether polyol has become the largest application field of propylene oxide, accounting for 77.23%; followed by dimethyl carbonate, accounting for 9.03%; propylene glycol ether ranks third, accounting for 3.17%.

According to the “2023-2027 Propylene Oxide Industry Market Status and Investment Prospects Forecast Report” released by the Industrial Research Center, epoxy As an important chemical raw material, propane has a long industrial chain and a wide range of terminal applications, resulting in huge market demand. Against this background, the production scale of my country’s propylene oxide enterprises has gradually expanded, and production capacity has increased. In 2022, my country’s propylene oxide production capacity will be approximately 3.964 million tons, a year-on-year increase of 3.53%.

From the perspective of production capacity distribution, my country’s propylene oxide production capacity is highly concentrated, mainly distributed in Shandong, Henan, Hebei, Jiangsu and other regions. Among them, Shandong has become the province with the largest propylene oxide production capacity in my country, accounting for 42.85%.

From the perspective of import and export, as China’s production capacity gradually increases, the import volume of propylene oxide has declined. According to data released by the General Administration of Customs, my country’s propylene oxide imports will be 1,842.01 tons in 2022, a decrease of 18.88% from 2021.

Industry analysts said that at present, the largest propylene oxide companies mainly include Zhenhai Refining and Chemical, Tianjin Dagu, Shandong Umbrella Yue, Wanhua Chemical, Shandong Binhua, Jishen Chemical, etc. As China’s production capacity structure gradually upgrades, the competition among enterprises in the propylene oxide industry becomes more intense. Some enterprises with backward production technologies are gradually eliminated, and the market gradually moves closer to enterprises with technological advantages and larger scales. In the future, the concentration of my country’s propylene oxide market will be It is expected to be improved.
