14butanediol Uses
1 4butanediol is an important organic chemical and fine chemical raw material which is the basic raw material for the production of polybutanediol terephthalate PBT engineering plastics and PBT fiber PBT plastic is one of the five most promising engineering plastics
14butanediol is the main raw material for the production of tetrahydrofuran tetrahydrofuran is an important organic solvent The PTMEG obtained by polymerization is the basic raw material for the production of high elasticity spandex Lycra fiber Spandex is mainly used in the production of high class sportswear swimming suits and other high elasticity knitwear
Gammabutyrolactone the downstream product of 1 4butanediol is the raw material for the production of 2pyrrolidinone and NMethylpyrrolidone products From this a series of high valueadded products such as NVinyl2Pyrrolidinone and Polyvinylpyrrolidone are derived which are widely used in the fields of pesticides medicine and cosmetics
14butanediol is also widely used as solvent pharmaceutical cosmetics plasticizer hardener pesticide herbicide foam leather fiber engineering plastics and so on
1 4butanediol BDO uses
Manufacturing Process of 14butanediol
1 4butynediol was prepared by acetylene and formaldehyde in the presence of catalyst and then by catalytic hydrogenation to produce 1 4butanediol It can also be prepared by the reaction of 1 3butadiene with acetic acid and oxygen through acetyl oxidation hydrogenation hydrolysis etc
