摘要: A process is disclosed in which hydrolysis and cyclization of an acetate ester of a 1,4-diol are carried out in separate reaction zones in the pressure of a solid acid catalyst and unreacted acetate ester recovered from each of the reaction zones is supplied to another zone thereby producing a hydrofuran and a 1,4-diol in any proportion.

摘要: Disclosed is a method of recovering butadiene gas from an acetoxylation process which method comprises steps: (a) contacting a butadiene-containing gas with acetic acid to effect the absorption of butadiene in acetic acid, (b) recycling the acetic acid containing butadiene to the acetoxylation process, (c) contacting the waste gas containing acetic acid from step (a) with water to effect the absorption of acetic acid in water and (d) recycling the water containing acetic acid to hydrolysis step of the acetoxylation product.
