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.

Description

technical field [0001] The invention relates to a reaction system for improving the utilization rate of reactants in the production of methyl chloride and an application thereof, belonging to the technical field of chemical process flow. Background technique [0002] Methyl chloride is an important raw material in the organic synthesis industry, mainly used in the production of methylchlorosilane, an important monomer of organosilicon. The gas-liquid phase catalytic method is a commonly used method in the process of synthesizing methyl chloride, mainly using methanol and excess hydrogen chloride gas as raw materials, and using ZnCl 2 As a catalyst, the reaction is carried out by bubbling. In order to increase the production capacity, a group of reactors connected in parallel with several reactors is usually used as the reaction equipment for synthesizing methyl chloride. The advantage of this method is that the process flow is simple, the reaction is mild, the operation is...
