Photoreactor for organic silicon photochlorination reaction

Abstract

The invention provides a photoreactor for organic silicon photochlorination reaction, which comprises a kettle body, the bottom of the kettle body is provided with a gas-liquid feed pipe, a mixture of chlorine and methyl trichlorosilane liquid enters the kettle body from the gas-liquid feed pipe, the top of the kettle body is laterally provided with a product discharge pipe, the top of the kettle body is vertically provided with a tail gas discharge pipe, and the tail gas discharge pipe is communicated with the product discharge pipe. The reaction kettle further comprises a light source pipe, the light source pipe extends into the lower portion in the kettle body from the top of the kettle body, a heating jacket is arranged outside the kettle body, and a water inlet and a water outlet are formed in the heating jacket. The photoreactor for the organic silicon photochlorination reaction is provided with a built-in light source, high in safety performance and capable of adjusting gas-liquid two-phase feeding.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a photoreactor for organosilicon photochlorination reaction. Background technique [0002] Methyltrichlorosilane reacts with chlorine to generate organosilane coupling agent. In the prior art, the reaction can be carried out by using the photochlorination method to synthesize the product. The light source of the traditional photochlorination synthesis method is set externally, and the traditional photoreactor is a glass reactor, and the external light source triggers the photochlorination reaction through the side wall of the reactor made of glass. However, due to the radiation area of ​​the traditional external light source, the utilization rate of the light source is low, and because it will irradiate the operators outside the equipment, it is impossible to use high-quality light sources with high energy, such as ultraviolet light, etc., so the speed of the photochl...

Problems solved by technology

However, due to the radiation area of ​​the traditional external light source, the utilization rate of the light source is low, and because it will irradiate the operators outside the equipment, it is impossible to use high-quality light sources with high energy, such as ultraviolet light, etc., so the speed of photochlorination reaction And the efficiency is not high, at the same time, the glass reactor designed for light transmission has low strength, and the equipment safety of photochlorination reaction needs to be improved
