الإجراء التجريبي

It is possible to obtain 1,4BG which is contained in the 1,4-butanediol-containing composition of the present invention by production methods which have hitherto been known. For example, there are included 1,4BG obtained by conducting an acetoxylation reaction using raw material butadiene, acetic acid, and oxygen to obtain diacetoxybutene that is an intermediate and hydrogenating and hydrolyzing the diacetoxybutene; 1,4BG obtained by using maleic acid, succinic acid, maleic anhydride, and/or fumaric acid as a raw material and hydrogenating such a raw material; crude 1,4BG obtained by hydrogenating butynediol obtained by bringing acetylene as a raw material into contact with a formaldehyde aqueous solution; 1,4BG obtained through oxidation of propylene; 1,4BG obtained by hydrogenating succinic acid obtained by a fermentation method; 1,4BG obtained by means of direct fermentation from a biomass such as a sugar, etc.; and the like.
