    • PURPOSE: A process for performing catalyzed multiphase reactions is developed which is suitable for manufacturing vinyl esters by catalytic reacting particularly carboxylic acids with acetylene. CONSTITUTION: The process for performing catalyzed multiphase reactions in a tube reactor is characterized in that catalysts are existed in a continuous phase, one or more starting materials are present in a dispersed phase, and a load factor is 0.8 or more. Catalytic multi-phase reaction comprises introducing catalyst in a continuous phase, where an adduct is present in a dispersed phase, and the load factor of the tube reactor is at least 0.8, wherein corresponding vinyl esters are obtained by catalytic multiphase reacting carboxylic acids with acetylene, the carboxylic acids have carbon numbers of 2 to 16, a metallic salt such as zinc salt of carboxylic acids is used as a catalyst, a weight ratio of the continuous phase or phases to the dispersed phase or phases is 2 or more, the continuous phase operates the upstream of a jet nozzle of the tube reactor, and one or more starting materials are dispersed by energy introduced into the tube reactor by the continuous phase.
