Embodiment Construction

[0012] refer to figure 1 , reactor (1), stripper (2), left heat exchanger (3), right heat exchanger (4), condensation tower (5), reflux tank (6), condenser (7), hydrogen chloride separation The tower (8), reboiler (9), and distillation tower (10) are assembled into one body through connecting pipelines (11) according to their system functions.

[0013] Under pressure, liquid methanol and hydrogen chloride are reacted to synthesize methyl chloride. Since the one-way reaction of methanol and hydrogen chloride cannot be completed, further reaction is performed after separation.

[0014] Methanol and excess 10% hydrogen chloride enter the reactor (1) from the lower part of the reactor (1) after heat exchange, the reaction temperature is 120° C., and the pressure is 1.06 MPa. On the reactor (1) is a distillation column (10), the reflux ratio of distillation is controlled at 1-2, and the methyl chloride saturated by hydrogen chloride is separated. Unreacted methanol and generated ...

Description

Technical field [0001] The invention relates to a technology for producing methyl chloride in the organic synthesis industry, in particular to a technology for producing methyl chloride by a gas-liquid phase non-catalytic method, which is suitable for chemical synthesis of methyl chloride. Background technique [0002] At present, methyl chloride is an important raw material in the organic synthesis industry, and is mainly used to produce methylchlorosilane, a raw material for organic silicon compounds. But the production technology is complex, the cost is high, and the product quality is also relatively poor. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a technology for producing methyl chloride in a gas-liquid phase non-catalytic method. The technology is not only reasonable in design and simple in manufacture, but also uses gas-liquid phase non-catalytic methanol method...
