  A process for making a butenyl ester from butadiene by reacting butadiene or a hydrocarbon fraction containing butadiene with a saturated aliphatic monocarboxylic acid, wherein the catalyst is rhenium (VII) oxide or an organic sulphonic acid containing at least (2) sulphonic acid groups per molecule wherein the ratio of the number of carbon atoms to the number of sulphonic acid groups in the organic sulphonic acid is in the range 1 : 1 to 1 : 0.15. Preferred catalysts are organic disulphonic acids for example ethane-1,2-disulphonic acid. The process can be used for making unsaturated esters, or, by hydrogenation of the product, for making saturated esters such as for example butyl acetate. Catalyst can be purified and recycled to the reactor.

  一种从丁二烯中制备丁烯酸酯的方法，包括将丁二烯或含有丁二烯的碳氢化合物与饱和脂肪族一元羧酸反应，其中催化剂为铼（VII）氧化物或含有每个分子至少（2）磺酸基团的有机磺酸，有机磺酸中碳原子数与磺酸基团数的比值在1：1至1：0.15范围内。优选的催化剂是有机二磺酸，例如乙烷-1,2-二磺酸。该方法可用于制备不饱和酯，或通过产物的加氢，用于制备饱和酯，例如醋酸丁酯。催化剂可以被净化并回收到反应器中。
