실험 절차
A 1 l stirred flash was charged with 500 g of vacuum gas oil and 6 g of an 85% strength phosphoric acid, and the mixture was heated to 300° C. 40 g/hour of methyl 3-methoxyvalerate from a stock vessel were fed, together with 10 l/hour of nitrogen, below the surface of the stirred oil/catalyst mixture. The gaseous products leaving the reaction vessel were cooled, and the condensate was investigated by gas chromatography. In this manner, 11.0 g/hour of methyl 3-pentenoate and 10.7 g/hour of 2-trans-pentenoate were obtained, inter alia, in addition to 7.5 g/hour of unconverted methyl 3-methoxyvalerate.
