γ- Butyrolactone (GBL) is a kind of solvent with high boiling point, strong solubility, good electrical properties and stability. The product is transparent and oily. It is completely miscible with water, soluble in ethanol, ether, benzene and acetone, and can dissolve many organic and inorganic compounds. The product has high safety, low toxicity, excellent stability and conductivity.
γ- Butyrolactone is widely used in the production of a-pyrrolidone, N-methyl pyrrolidone, polyvinylpyrrolidone and acetyl γ- Butyrolactone and other chemical products can be used as anesthetics and sedatives in the pharmaceutical industry. Ciprofloxacin and interferon can be synthesized. They are intermediates of vitamins and Cyclopropylamine; In agriculture and forestry, it can produce intermediates of plant growth agents and insecticides; In addition, the product can also be used in antioxidant, plasticizer, extractant, absorbent, dispersant, fixing agent, coagulant, battery, capacitor production and many other fields.
Industrial production γ- The methods of butyrolactone mainly include furfural method, 1,4-butanediol dehydrogenation method, maleic anhydride hydrogenation method and succinic acid hydrogenation method. Among them, 1,4-butanediol dehydrogenation method and maleic anhydride hydrogenation method are the two main methods in China.
γ- Butyrolactone was first developed in Europe and the United States. BASF and GAF are the most well-known enterprises in the world, while China is the most famous γ- Butyrolactone started relatively late and developed greatly at the end of 1980s γ- Butyrolactone production technology has been breakthrough, the number of production enterprises is increasing.
because γ- Butyrolactone has a wide range of applications. In recent years, the product has achieved steady development, and the scale and strength of the enterprise are growing. According to the "2021-2026" issued by xinsijie γ- According to the report of in-depth market research and investment prospect forecast analysis of butyrolactone industry, at present, China's γ- Butyrolactone market is oligopoly market with high market concentration, among which top 5 enterprises account for 30% - 50%. The enterprises with strong competitive power in the industry mainly include Meiqi chemical, Yuneng chemical, Guorong chemical, Persson and other enterprises. But in addition to these enterprises, there are also many small and medium-sized enterprises in China, which produce a lot of products γ- The quality of butyrolactone is uneven, mainly to seize the low-end market, the competition between enterprises is very fierce.
New thinking investment analysts pointed out that in recent years, domestic γ- Butyrolactone industry faces both opportunities and challenges. The favorable factors for the development of the industry include: γ- Butyrolactone is widely used in the downstream. In recent years, the downstream N-methylpyrrolidone, medicine, battery and other industries have achieved rapid development, promoting the expansion of product demand scale; More and more enterprises extend γ- Butyrolactone industry chain to promote the continuous upgrading of the industry. The main challenges of the industry development come from: the increasing market supply capacity, product market competition has intensified; The development of traditional chemical industry is slowing down, the pressure of environmental protection is increasing, and the industrial environment is tightening.
