γ-Butyrolactone (GBL) has a wide range of application fields. my country’s supply capacity of electronic grade γ-butyrolactone is increasing day by day.

γ-Butyrolactone (GBL) is an oxygen-containing five-membered heterocyclic compound. The product is transparent and oily, soluble in ethanol, ether, benzene and acetone. γ-Butyrolactone is an important fine chemical intermediate with strong solubility, good stability, low toxicity, and excellent conductivity. It can be used to produce vitamin B1, aminobutyric acid, ciprofloxacin, and polyethylene. methyl pyrrolidone, N-methyl-2-pyrrolidone, 2-pyrrolidone and other products.

There are various industrial production processes for γ-butyrolactone, mainly including furfural method, maleic anhydride hydrogenation method, 1,4-butanediol dehydrogenation method, succinic acid hydrogenation method, Reppe method, etc. my country uses 1, 4-Butanediol dehydrogenation method and maleic anhydride hydrogenation method are the main ones. The γ-butyrolactone industry in European and American countries started early, and the main production companies include BASF of Germany and GAF ​​of the United States.

According to the “2022-2026 China γ-butyrolactone (GBL) industry market supply and demand status and development trend forecast report” shows that compared with Europe and the United States and other countries, my country’s γ-butyrolactone industry started late. However, since the 21st century, with the advancement of production technology, my country’s γ-butyrolactone production scale has continued to expand, and industry development has tended to Mature. my country’s γ-butyrolactone market is highly concentrated. The main manufacturers include Maiqi Chemical, Guorong Chemical, Dongjing Biotech, Yuneng Chemical, and Pearson.

my country is a major producer of γ-butyrolactone. In addition to large-scale production enterprises, there are also many small and medium-sized enterprises in the market. Due to the low technical level and unstable product quality of small and medium-sized enterprises, the quality of domestically produced γ-butyrolactone is uneven. Conducive to the long-term sustainable development of the industry. In the context of high-quality development of the manufacturing industry, the γ-butyrolactone industry structure needs to be optimized urgently.

As a fine chemical raw material, γ-butyrolactone has a wide range of applications, involving textiles, food, pesticides, medicine, petrochemicals, lithium batteries and other fields. In recent years, with the development of the new energy vehicle industry, the lithium battery market has developed rapidly, and the global market size will exceed US$41 billion in 2021. The rapid development of the lithium battery industry has driven the release of market demand for electronic-grade γ-butyrolactone, an upstream raw material.

The production of electronic grade γ-butyrolactone is difficult and requires high purity. In 2019, Maichi Chemical realized the industrial production of electronic grade γ-butyrolactone, with a product purity of 99.95%, filling a gap in the domestic market. In December 2022, Dongjing Biotech’s “100,000 tons per year γ-butyrolactone project” was successfully put into operation at one time, and the product purity was ≥99.95%. The commissioning of this project will help optimize the γ-butyrolactone industrial structure and improve Electronic grade γ-butyrolactone supply capability.

Industry analysts said that my country’s γ-butyrolactone market started late, but with technological advancement and demand release, γ-butyrolactone has The lactone industry has developed rapidly, and my country has become a major producer of γ-butyrolactone. my country’s γ-butyrolactone industry structure is unbalanced and the supply of high-purity electronic grade γ-butyrolactone is insufficient. Against the background of the rapid development of new energy vehicles and lithium battery industries, relevant companies should seize the opportunity of growing market demand and promote the high-end industry develop.
