THE METHOD OF MAKING AN ALKENYL ESTER WHICH COMPRISES FORMING A SOLUTION OF AN ALKENYL HALIDE SELECTED FROM THE GROUP CONSISTING OF ALLYL AND METHYALLYL CHLORIDES, BROMIDES, AND IODIDES AND AN ALKALI METAL SALT OF AN UNSUBSTITUTED BENZENE CARBOXYLIC ACID HAVING 7-10 CARBOBN ATOMS AND 1-4 CARBOXYL GROUPS TO THE MOLEUCLE IN A LIQUID REACTION PROMOTER SELECTED FROM THE GROUP CONSISTING OF MONO- AND DIMETHYL FORMADIES AND ACETAMIDES AND MONO- AND DIETHYL FORMAMIDES AND ACETAMIDES, HEATING THE RESULTING SOLUTION AT A TEMPARATURE NOT ABOVE THE REFLUXING TEMPERATURE THEREOF UNTIL THE ALKALI METAL HALIDE WHICH PRECIPITATES AS THE BY-PRODUCT CEASES TO PRECIPITATE AND THEN FILTERING OUT THE SAID HALIDE, THE PROPORTION OF THE ALKENYL HALIDE USED BEING AT LEAST APPROXIMATELY EQUIVALENT TO THE SAID AND THE PROMOTER BEING IN AMOUNT AT LEAST APPROXIMATELY EQUAL IN WEIGHT TO THE SAID HALIDE.
