The market demand for 1,3-dioxanalene (DOL) is increasingly strong. Jingjing Pharmaceutical is a representative enterprise in my country.

​ ​ 1,3-dioxolane (DOL), also known as 1,3-dioxolane, has a chemical formula of C3H6O2 and is an organic compound. 1,3-Dioxane appears as a colorless and transparent liquid with an ether-like odor, and is soluble in water, ether, ethanol and acetone. 1,3-Dioxopenta has excellent properties and is widely used as an organic solvent in lithium-ion batteries, catalysts, pesticides, medicine, chemical industry, automobile manufacturing and other fields.

​​ 1,3-Dioxacyclo is usually produced by the reaction of ethylene glycol and paraformaldehyde, with ethylene glycol as its main raw material. my country is the world’s largest producer and consumer of ethylene glycol. In 2022, my country’s ethylene glycol production will reach nearly 12 million tons, a year-on-year increase of nearly 10%. In terms of market price, my country’s ethylene glycol market has been in an oversupply situation for a long time. Coupled with the mature technology development, its price has continued to decline, reaching nearly 3,800 yuan/ton in December 2022. The abundant supply of raw materials and low production costs bring advantages to the development of my country’s 1,3-dioxanol industry.

Benefiting from the improved prosperity of the new energy automobile industry, the lithium-ion battery market space continues to expand. 1,3-dioxopenta can be used as an electrolytic solvent for lithium-ion batteries to improve the battery’s charge-discharge cycle efficiency and the interface stability of the electrode. According to statistics from the Ministry of Industry and Information Technology, my country’s lithium-ion battery production will reach 750GWh in 2022, a year-on-year increase of more than 130%. As the development of downstream industries accelerates, my country’s market demand for 1,3-dioxane is increasingly strong. According to the “2023-2028 China 1,3-Dioxane (DOL) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》shows that my country’s demand for 1,3-dioxane will reach nearly 150,000 tons in 2022.

North China and East China are the main production areas of 1,3-dioxanone in my country, and Jingjing Pharmaceutical, Jinshengchang Chemical, Longyu Chemical, etc. are the main manufacturers in my country. my country’s 1,3-dioxin industry started early. After years of experience accumulation, the production technology has matured, and product quality and output rank among the world’s leaders. However, in recent years, as the national environmental protection policy has become stricter, my country’s 1,3-dioxanone production capacity has declined, driving imports to continue to grow. Japan, the United States, Brazil, Germany and India are my country’s main importing countries.

Jingjing Pharmaceutical is a representative enterprise of 1,3-dioxanone in my country, and its holding subsidiary Senxuan Pharmaceutical is the largest supplier of 1,3-dioxanone in my country. The 1,3-dioxanone independently produced by Senxuan Pharmaceutical can be used as an electrolytic solvent for lithium iron phosphate batteries and as a pharmaceutical intermediate. Currently, the company has an annual production capacity of 3,000 tons of 1,3-dioxanone.

Industry analysts said that as an excellent organic solvent, 1,3-dioxanone has broad application prospects in many fields. , as the prosperity of the lithium-ion battery industry increases, its market demand will further grow. my country’s 1,3-dioxanol industry started early, but its production capacity has declined in recent years due to the impact of national environmental protection policies. In the future, as the independent research and development capabilities of local enterprises improve, my country’s 1,3-dioxanol industry will gradually develop in a green and environmentally friendly direction.
