BDO,It is an important basic organic chemical and fine chemical raw material, developed downstream, and can be used to produce more than 200 kinds of fine chemical products, involving many fields, such as automobile manufacturing, electronic and electrical appliances, information communication, engineering plastics, building materials, machinery, petrochemical, textile, medicine, printing, cosmetics and so on.
1,4-Butanediol is a colorless oily liquid with a combustible melting point of 20.1°C. Boiling point 235℃. Flash point (open cup) 121℃. Relative density d 4201.0171. refractive index nD201.4461. viscosity (25℃) 71.5mPa-s. hygroscopic. Miscible with water, soluble in methanol, ethanol, acetone, slightly soluble in ether.
With strong reactivity, it can carry out oxidation, dehydration, replacement, polymerization, amination, esterification, halogenation and other chemical reactions to produce a series of important chemical products. Ketone, slightly soluble in ether.
Made from acetylene and formaldehyde in the presence of a catalyst to make 1,4-butynediol, and then catalytic hydrogenation. It can also be made from 1,3-butadiene with acetic acid and oxygen by acetyl oxidation, hydrogenation, hydrolysis and other reactions.
Packaging and storage and transportation
It is packed in aluminum, galvanized iron barrels or plastic barrels, or stored and transported in tanker trucks as flammable and toxic goods. Because the melting point is as high as 20℃, the tanker should be equipped with heating tube.
1,4-Butanediol is widely used in the production of polybutylene terephthalate (PBT), tetrahydrofuran (THF), gamma-butyrolactone (GBL), N-methyl-pyrrolidone (NMP), N-vinylpyrrolidone (NVP), polyurethane resin (PU) and high-performance elastic fiber SPANDEX (spandex), and other fine chemicals with high added value. It is widely used as solvents, pharmaceuticals and cosmetics, plasticizers, curing agents, pesticides, herbicides, foams for leather, fibers, engineering plastics, etc.
