What is 1.4-Butanediol

1.4-Butanediol is an important raw material for the production of spandex, plastics, elastomers and films. BDO is used as a base material as well as a starting material for other SA derivatives such as THF and GBL. THF is produced from 1,4-DO in the presence of phosphoric acid under high temperature conditions. Figure 5 shows five known chemical processes for producing 1,4-PDO. Reppe chemistry was one of the first technologies to produce 1,4-butanediol from acetylene and formaldehyde.

Poly butylene adipate-co-terephthalate (PBAT), also known as polybutylene terephthalate, is a semi-aromatic, biodegradable thermoplastic copolymer that can be easily molded and thermoformed. Poly butylene adipate-co-terephthalate is a random copolymer of 1,4-butanediol, adipic acid, and dimethyl terephthalate (DMT) monomers. PBAT has many attractive properties similar to polyethylene. For example, poly butylene adipate-co-terephthalate has a relatively high elongation at break (30-40%).

1.4-Butanediol

图片
1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

What kinds of products may use NMP(N-methylpyrrolidone)? N-Methylpyrrolidone ( NMP ) harms the developing fetus when tested in pregnant animals. It is toxic to the reproductive system of male and female test animals. The reproductive effects of NMP( N-methylpyrrolidone ) have not been studied in humans. Based on the animal tests, you should treat NMP as a potential human reproductive hazard. Overexposure to NMP irritates the eyes, skin, nose, and throat. It can also affect the central nervous system or brain causing symptoms of drunkenness similar to the effects of drinking alcohol. NMP is easily absorbed through the skin. It is widely used to replace methylene chloride and other chlorinated solvents that harm the environment and health. HESIS revised this Health Hazard Advisory to inform workers and employers that Cal/OSHA has adopted a Permissible Exposure Limit for this substance.
