A process for the preparation of butenediol diacetate by reacting butadiene with oxygen and acetic acid or with a compound which liberates acetic acid under the reaction conditions, over a solid catalyst which contains a platinum metal and one or more elements of main group 5 or 6, in the presence of butanediol diacetate, butanediol monoacetate, butanediol or a mixture of these, and the use of the butenediol diacetate, thus obtained, to prepare butane-1,4-diol by hydrogenating and then hydrolyzing the diacetate. |
