Abstract

The invention discloses a gas-liquid reaction method and a special device. During the reaction, a raw material liquid enters a tubular reactor from a raw material liquid inlet of the tubular reactor, and raw material gas is fully mixed with a reaction liquid or the raw material liquid at a mixed flow circulating pump inlet and subjected to a gas-liquid reaction in a circulating pipeline and the tubular reactor along the flow path; energy supplement is performed by the aid of a ripening reactor outer jacket at the initial stage of the reaction, and automatic energy supplement is set after the reaction system is stabilized; forced circulating reaction is adopted. The working performance is good, the yield is effectively increased, and byproducts are reduced or avoided.

Description
