Benefiting from the development of the PGA industry, the market demand for dimethyl oxalate (DMO) is rising

Dimethyl oxalate (DMO), also known as dimethyl oxalate, is an important pharmaceutical and chemical raw material. It is often used in the production of plasticizers, vitamin B13 intermediates, and pesticide production. Dimethyl oxalate is an important intermediate product in the coal-to-ethylene glycol process route. Dimethyl oxalate can be hydrogenated to prepare ethylene glycol, or it can be hydrogenated to prepare methyl glycolate (MG). It is added through the addition of catalytic Replacement can be switched from the production of ethylene glycol to the production of methyl glycolate (MG) and glycolic acid (GA), and then to the production of PGA.

Polyglycolic acid (PGA) is an ideal degradable material with the advantage of being non-toxic and non-toxic. The final degradation products are carbon dioxide and water. Therefore, it has attracted global attention. It has been certified in Japan, the United States and some European countries, and is It is used in the fields of degradable plastics and medical care. my country’s PGA slices currently rely on imports, and due to the relatively high cost, they are currently mainly used in the field of medical materials.

The international production of PGA mainly uses glycolic acid, acetate, and glycolide as raw materials, which are condensed into products under the action of catalysts. The production process mainly uses glycolide ring-opening polymerization. China is a large country that produces ethylene glycol from coal, and it is highly feasible to use dimethyl oxalate to produce PGA. With the release of “my country’s Polyglycolic Acid (PGA) Biodegradable Plastic Industry Accelerates” by the Ministry of Industry and Information Technology in 2020, it indicates that my country’s PGA industry will develop rapidly, and the application demand for dimethyl oxalate may continue to grow.

According to the “China Dimethyl Oxalate (DMO) Industry Market Supply and Demand Status and Development Trend Forecast Report 2021-2025” released by the Industrial Research Center shows that dimethyl oxalate is an important intermediate product in the coal-to-ethylene glycol process route. In 2022, my country’s coal-to-ethylene glycol production capacity will reach about 14 million tons, which also means that in 2022, my country’s coal-to-ethylene glycol production capacity will reach about 21.2 million tons. tons/year dimethyl oxalate production capacity. And in the future, with the rapid development of the PGA industry and the growth of market size, the production capacity of dimethyl oxalate will continue to increase.

In terms of market competition, there are currently relatively few dimethyl oxalate manufacturers. In 2020, Donghua Technology and Yulin Chemical cooperated to establish a 1.8 million tons/year ethylene glycol project. The main products produced are dimethyl oxalate and ethylene glycol. Alcohol, among which Donghua Technology provides technical and equipment support, while Yulin Chemical is responsible for project construction.

Industrial analysts said that PGA is an excellent degradable material, but due to technical limitations, large-scale production of PGA has not been achieved in China. . The large-scale development of PGA is supported by the government. As an important raw material in the industrial production of PGA, dimethyl oxalate will have high market demand in the future. In terms of production, my country is a major producer of coal-to-ethylene glycol. In recent years, with the establishment of coal-to-ethylene glycol projects, dimethyl oxalate production capacity and output have continued to increase, and the industry has developed rapidly.
