Gamma butyrolactone (GBL) is a solvent with high boiling point, strong solubility, good electrical properties, and stability. The product is transparent, oily, and completely miscible with water. It is 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.
Gamma butyrolactone has a wide range of applications and can be used to produce chemical products such as a-pyrrolidone, N-methylpyrrolidone, polyvinylpyrrolidone, acetyl gamma butyrolactone, etc. In the pharmaceutical industry, it can be used as an anesthetic and sedative, and can synthesize ciprofloxacin and interferon. It is an intermediate for vitamins, cyclopropylamine, etc; In agriculture and forestry, intermediates such as plant growth agents and insecticides can be produced; In addition, this product can also be used in many fields such as antioxidants, plasticizers, extractants, absorbents, dispersants, fixing agents, coagulants, batteries, capacitor manufacturing, etc.
The methods for industrial production of γ - butyrolactone mainly include four different processes: 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 currently the two main methods in China.
Gamma butyrolactone * * * has developed early with European and American countries, and internationally renowned enterprises mainly include BASF and GAF in the United States. However, China's gamma butyrolactone started relatively late and only had significant development in the late 1980s. Since the 21st century, with breakthroughs in domestic gamma butyrolactone production technology, the number of production enterprises has been increasing.
Due to the wide range of applications of gamma butyrolactone, the product has achieved steady development in recent years, and the scale and strength of the enterprise have continued to grow. According to the "2021-2026 Gamma butyrolactone Industry Market Depth Research and Investment Prospect Forecast Analysis Report" released by Xinsijie, the current gamma butyrolactone market in China is an oligopolistic market with high market concentration, among which the market share of the top 5 enterprises in the industry is between 30% and 50%. The enterprises with strong competitive strength in the industry mainly include Maiqi Chemical, Yuneng Chemical, Guorong Chemical, Pailson and other enterprises. But in addition to these enterprises, there are also many small and medium-sized enterprises in China. The quality of gamma butyrolactone produced by these enterprises varies greatly, mainly occupying the mid to low end market, and the competition between enterprises is very fierce.
According to analysts from Xinsijie Investment, the domestic gamma butyrolactone industry has faced both opportunities and challenges in recent years. The favorable factors for industry development include: the widespread downstream application of gamma butyrolactone, and in recent years, downstream industries such as N-methylpyrrolidone, pharmaceuticals, and batteries have achieved rapid development, promoting the expansion of product demand scale; More and more companies are extending the gamma butyrolactone industry chain, driving the continuous upgrading of the industry. The main challenges facing the development of the industry come from the increasing market supply capacity and intensified competition in the product market; The development of traditional chemical industry is slowing down, environmental pressure is increasing, and the industrial environment is becoming tighter.
