Markor 1,4-Butanediol 1,4-BDO 110-63-4

...

Basic parameters

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) In addition to fine chemical products with high added value such as high-performance elastic fiber SPANDEX (spandex), they are widely used as solvents, pharmaceutical cosmetics, plasticizers, curing agents, pesticides, herbicides, foam artificial leather, fibers, engineering Plastic etc.

Chemical Properties
Has strong reactivity, capable of oxidation, dehydration, and replacement , polymerization, amination, esterification, halogenation and other chemical reactions to generate a series of important chemical products. Hygroscopic, miscible with water, soluble in methanol, ethanol, acetone.

Production process
Made from acetylene and formaldehyde in the presence of a catalyst 1,4- Butynediol, and then obtained by catalytic hydrogenation. It can also be prepared by the reaction of 1,3-butadiene with acetic acid and oxygen through acetyl oxidation, hydrogenation and hydrolysis.

Packaging and storage
Packed in aluminum, galvanized iron drum or plastic drum, or in Tank trucks are stored and transported as flammable and toxic substances. Because the melting point is as high as 20°C, a heating tube should be installed in the tank car.
