PROBLEM TO BE SOLVED: To provide a method capable of improving the multi-phase reaction performance in the case of a critical phase combination based on the reverse flow principle. SOLUTION: The method is a method for performing a multi-phase reaction in a continuous operation tubular reactor operated based on the reverse flow principle. The tubular reactor comprises a built-in packing or does not comprise it for enlarging the reaction interface and is employed to repeat the movement of a liquid-phase reactor members (components) flowing downward as a thin film therein and the material movement of a continuous gas component flowing upward in the tubular reactor, that is, to cause reaction with each other and temporarily decrease gas penetration to the tubular reactor and/or repeat temporary pressure increase at the gas outlet of the reactor, so that the vapor phase gives impact to promote a thin film growth and inhibits liquid-phase stagnation and probably owing to the application of the impact to the vapor phase flow direction, the flow is reversed and the vapor phase flows temporarily downward.
