Abstract
A method for preparing bio-based 1,4-butanediol (BDO) is provided, including: mixing succinic acid from a bio-based source and an alcohol compound to obtain a mixture, and subjecting the mixture to esterification to obtain an oligomer polyester; subjecting the oligomer polyester to hydrogenation reduction in the presence of a catalyst to obtain a 1,4-BDO crude product; and purifying the 1,4-BDO crude product to obtain the bio-based 1,4-BDO.
