Flow chemistry reactor for gas generation at high temperature

Abstract

The invention provides a flow chemistry reactor for gas generation at high temperature, mainly designed to solve the technical problems of uncontrollable reaction liquid retention time, poor liquid flow stability and strong back-mixing effect in a tubular reactor relating to a reaction with a gas generated at high temperature. The following technical solution is developed: a flow chemistry reactorfor gas generation at high temperature is characterized by comprising a stainless steel coil reactor, a high-temperature drying oven, a back-pressure valve, a feed tank, a pump and a collection tank,wherein the feed tank is connected to the pump and the stainless steel coil reactor through pipes in sequence; the stainless steel coil reactor is placed in the drying oven; a coil of the stainless steel coil reactor forms a liquid flow channel; the stainless steel coil reactor is provided with an inlet, and an outlet which is connected to the back-pressure valve; and the back-pressure valve is connected with the collection tank through a pipe. The flow chemistry reactor for gas generation at high temperature is used for research and development, and large-scale production of a reaction witha gas generated at high temperature.

Description

technical field [0001] The invention relates to a chemical reactor, in particular to a flow chemical reactor for high-temperature gas generation, which is used in high-temperature condensation and decarboxylation reactions with gas generation to eliminate the uncontrollable residence time of the reaction solution and reduce the Liquid flow instability and back-mixing effects, suitable for research and development, especially suitable for scale-up production. Background technique [0002] High-temperature ovens, tubular reactors and back pressure valves are widely used in laboratory research and development, but for reactions with gas generation, it is difficult to control the residence time, the stability of liquid fluidity is poor, and the back-mixing effect is serious, so it is difficult to apply to research and development and Production scaled up. For high-temperature condensation reaction and decarboxylation reaction, the operation is simple, the selectivity is high, a...
