【Product properties】
γ-butyrolactone is a colorless, non-toxic and transparent oily liquid, with a certain hygroscopicity and slight odor, is a high boiling point, strong solubility, good electrical properties and stability of the solvent, and water, alcohol, esters, ethers, ketones and aromatics miscibility, can dissolve many organic and inorganic compounds, safe and easy to use. It is also an important raw material for organic synthesis, mainly used for the synthesis of pyrrolidone series products, cyclopropylamine, acetyl-γ-butyrolactone, etc.. In addition,γ-butyrolactone is also used in agricultural chemicals, polymers and dyes, printing solvents, petrochemical extractants, and can also produce spices, pharmaceutical intermediates, rust removers, etc.
【Product features】
γ-butyrolactone is produced by Frantek company in the United States, with advanced and mature technology, high product purity, water content, color, acidity and other indicators have reached the standard of excellent products, which is used by many domestic manufacturers and widely recognized by many customers. In order to improve product quality, our company continues to carry out research and development, among which the "purification method of N-methylpyrrolidone and γ-butyrolactone" has been successfully declared for national invention patent.
Application:
γ-butyrolactone is a high boiling point solvent with strong solubility, non-toxicity, safe and convenient use and management; used as an extractant for butadiene, aromatics and advanced greases in petroleum processing; used as a spinning solvent for acrylonitrile fiber in the chemical fiber industry, and is a dyeing aid for wool, nylon, acrylonitrile and other fibers; in organic synthesis, GBL also has a wide range of uses, it is the synthesis of α-pyrrolidone, N-methylpyrrolidone, vinylpyrrolidone, acetyl-γ-butyrolactone. Raw materials such as cyclopropylamine, which is an intermediate for the synthesis of insecticides, herbicides, drugs for brain rehabilitation, cipropylhaloperic acid, vitamin B1, chlorophyll, etc., and is also used for the synthesis of chlorophenoxybutyric acid herbicides, plant growth regulators.
