Abstract

The invention discloses a chlorination reaction device for cyanate ester synthesis, wherein the chlorination reaction device comprises a mixing tank, a reaction tank and a treatment tank which are arranged side by side. The invention relates to the technical field of chemical production devices. An atomizing assembly is arranged at the top of a dissolving tank, chlorine is sprayed into the dissolving tank, the chlorine makes full contact with atomized water liquid, the dissolving rate of the chlorine in water is greatly increased, cooling liquid is introduced into a spiral cooling groove in a heat preservation sleeve, the dissolving degree of the chlorine in the water can be further enhanced under the low-temperature condition, and then high-concentration chlorine water is obtained; and the high-concentration chlorine water is mixed with sodium cyanide in a static mixer, meanwhile, the static mixer is kept at a low temperature in cooperation with a jacket mechanism, the high-concentration chlorine water and the sodium cyanide can have a high conversion rate in a low-temperature environment, the conversion rate of the sodium cyanide is increased, and the amount of cyanide ions entering wastewater is effectively reduced, so that the treatment difficulty of the wastewater generated by the chlorination reaction is reduced.

Description

Technical field [0001] The present invention relates to the technical field of chemical production apparatus, in particular a chlorinated reaction apparatus for use in cyanate synthesis. Background technique [0002] During the chlorination reaction of the cyanate synthesis, the chlorination yield is only 75%, and there is still 25% sodium cyanide. The cyanide, cyanide ions enter three abrasives in various forms, resulting in The production cost of cyanate is greatly improved, and the cyano ions have a high salt, high COD produced by the chlorination reaction after entering the wastewater, resulting in a difficult treatment of subsequent wastewater, and therefore, the present invention provides a use of cyanate synthesis The chlorination reaction device to solve the above problems. Inventive content [0003] (1) Solving technical problems [0004] For the shortcomings of the prior art, the present invention provides a chlorinated reaction apparatus for use in cyanate synthesis, ...
