应用
1,4-Butanediol is commonly used as a solvent in the chemical industry to manufacture gamma-butyrolactone and elastic fibers like spandex. It is used as a cross-linking agent for thermoplastic urethanes, polyester plasticizers, paints and coatings. It undergoes dehydration in the presence of phosphoric acid yielded teterahydrofuran, which is an important solvent used for various applications. It acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU). It finds application as an industrial cleaner and a glue remover.

备注
Incompatible with strong oxidizing agents, acid chlorides, acid anhydrides and reducing agents.

产品说明

应用

1,4-Butanediol can be used as a reactant to prepare:

• Homoallyl alcohol (3-buten-1-ol) and tetrahydrofuran via vapor-phase dehydration using ZrO₂ as a catalyst.
• Poly(1,4-butanediol succinate) polymer by reacting with succinic anhydride.
• Biodegradable homopolyesters [poly(butylene succinate) and poly(butylene adipate)] and copolyesters [poly(butylene succinate-co-butylene adipate)] by treating with succinic acid and adipic acid via esterification and deglycolization reaction.
• Poly(1,4-butyl sebacate) by polyesterification reaction with sebacic acid or its derivatives.
