Description

technical field [0001] The invention relates to an energy-saving graphite heat exchanger which utilizes monochloromethane to synthesize heat energy and a production method. Background technique [0002] At present, a large amount of industrial production of monochloromethane is produced by hydrochlorination, that is, using methanol and hydrogen chloride to react under the action of a catalyst to generate monochloromethane and water. The reaction principle is as follows: [0003] CH 3 OH+HCl Catalyst CH 3 Cl + H 2 O+ heat 29.9kJ / mol. [0004] In order to obtain the ideal product, it is usually necessary to heat methanol to vaporize, react with the heated hydrogen chloride gas at a certain temperature, and the reacted product needs to be cooled for separation and extraction. In this production process, the material needs to be heated before the reaction, and the material needs to be cooled after the reaction, and the heat released in the reaction is not recycled.
