Problems solved by technology
However, the existing microchannel reactors generally adopt an overall design, and disassembly and assembly are difficult, and users cannot quickly install them according to needs, especially for the factory production process of nitrochlorobenzene synthesis. Once the plate of the microchannel reactor is damaged , a microchannel reactor needs to be shut down and sent for inspection, which is very inconvenient to use; at the same time, the existing microchannel reactor is relatively universal and cannot be used for the production of nitrochlorobenzene. not so good

The invention discloses a micro-channel reactor for synthesizing nitrochlorobenzene, and relates to the technical field of nitrochlorobenzene synthesis production, the micro-channel reactor comprises a bottom fixing frame, the middle of the top of the bottom fixing frame is fixedly provided with an upper support through a bolt, and the upper surface of the upper support is provided with a positioning mounting hole. The device is provided with the positioning adjusting assembly and the micro-channel reaction assembly, raw material liquid enters a liquid inlet pipe from a liquid inlet and then is conveyed into a micro-channel through a first side pipe, micro-channel reaction balls in the micro-channel can block the raw material liquid, micro-channel reaction holes in the micro-channel reaction balls can enlarge the contact area of the liquid, and the contact area of the liquid is increased. Under full contact, nitration reaction is rapidly carried out, the movable plate and the fixed plate can clamp the microchannel reaction assembly, installation of the microchannel reaction assembly is facilitated, the whole device adopts a modularized installation mode, and workers can install the microchannel reaction assembly according to actual conditions.
Description
technical field [0001] The invention relates to the technical field of synthesizing nitrochlorobenzene, in particular to a microchannel reactor for synthesizing nitrochlorobenzene. Background technique [0002] Nitrochlorobenzene is after nitric acid, sulfuric acid are made into mixed acid, carries out nitration reaction with chlorobenzene, generates nitrochlorobenzene (para-position 65%, ortho-position 34%, meta-position 1%), then separates nitrochlorobenzene and Spent acid, separated, rectified and crystallized to obtain nitrochlorobenzene. Nitrochlorobenzene is a basic chemical, and the heat release during nitration is large. Most factories still use relatively primitive equipment in the production of nitrochlorobenzene, and the equipment is relatively heavy. On the one hand, the increase in temperature is conducive to the rapid progress of the reaction On the other hand, if the heat exchange is unfavorable, it is likely to cause temperature loss and accidents, and the e...
