Abstract

The invention relates to a reaction system for increasing utilization ratio of reactants in chloromethane production and an application of the reaction system. The system comprises a reaction unit, a condenser and a return tank, wherein the reaction unit comprises 2 to 5 reactors which are in series connection, a reactor charging opening I is formed in the bottom end of each reactor, a reactor discharging opening and a reactor charging opening II are formed in the top end of each reactor, a discharging opening of the reaction unit is connected with a condenser charging opening of the condenser, a condenser discharging opening of the condenser is connected with a return tank charging opening of the return tank, a return tank discharging opening I and a return tank discharging opening II are separately formed in the top end and bottom end of the return tank, and the return tank discharging opening II of the return tank is separately connected with the reactor charging openings II of all the reactors. The reaction system disclosed by the invention is applied to the production of chloromethane from methanol and hydrogen chloride, which serve as raw materials, and the methanol and the hydrogen chloride can be in full reaction as much as possible, so that the arranging of a methanol recovery device and a hydrogen chloride recovery device is avoided, energy is saved, and environmental pollution is reduced.
