Procedure

For example, 1,4-butanediol may be produced by means of chemical synthesis of succinic acid, succinic anhydride, a succinic acid ester, maleic acid, maleic anhydride, a maleic acid ester, tetrahydrofuran, γ-butyrolactone, or the like, as obtained by the fermentation method, or 1,4-butanediol may be produced from 1,3-butadiene obtained by the fermentation process. Of these, a method of obtaining 1,4-butanediol by means of hydrogenation of succinic acid in the presence of a reduction catalyst is efficient and preferable.
