General description

1,4-Butanediol is an industrial solvent that is mainly used in the preparation of important polymers such as polyurethanes and polybutylene terephthalate (PET).

Application

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.
