一般說明
1,4-Butanediol is an industrial solvent that is mainly used in the preparation of important polymers such as polyurethanes and polybutylene terephthalate (PET).
應用
1,4-Butanediol may be used in the preparation of 3-buten-1-ol and tetrahydrofuran via dehydration. It may also be used as a reducing agent for carbonyl compounds to form the corresponding alcohols via transfer hydrogenation reaction.

The enzyme Candida antarctica lipase B was subjected to site directed mutagenesis suggested by molecular modelling. The selectivity for the enzyme increased towards a range of diols over their corresponding monoesters as an effect of the mutations.
