Purpose
1, 4-Butanediol is widely used, except for the production of polybutylene terephthalate (PBT), tetrahydrofuran (THF), γ-butyrolactone( GBL), N-methylpyrrolidone (NMP), N-vinylpyrrolidone (NVP), polyurethane resin (PU) and high-performance elastic fiber SPANDEX (spandex) and other fine chemical products with high added value, widely used as Solvents, pharmaceutical cosmetics, plasticizers, curing agents, pesticides, herbicides, foam artificial leather, fibers, engineering plastics and brighteners in electroplating industries, etc.
has a great With strong reactivity, it can carry out various chemical reactions such as oxidation, dehydration, replacement, polymerization, esterification, halogenation, etc., and produce a series of important chemical products. Hygroscopic, miscible with water, soluble in methanol and ethanol.
Packaging and Storage
Aluminum , galvanized iron drums or plastic drums, or stored and transported by tank trucks as flammable and toxic materials. Because the melting point is as high as 20°C, a heating tube should be installed in the tank car.
