A process for the production of C5-acetate

There is provided a process for the preparation of C¶5¶ acetate for the vitamin A synthesis by hydroformylation of 3,4-diacetoxy-butene (1), (3,4-DABE) is proposed, followed by a 3,4-DABE uses that have been obtained by the acetoxylation of 1,3-butadiene with acetic acid and air in the presence of a catalyst and distillative separation of the thereby formed as a by-product 3,4-DABE.
