Description

technical field [0001] The invention belongs to the synthesis process of continuous production process, and particularly relates to a continuous cyanation device and a continuous cyanation process using the continuous cyanation device. Background technique [0002] The metathesis reaction refers to the reaction in which two compounds exchange components with each other to form two other compounds. It is one of the four basic reaction types and can be expressed concisely with the general formula: AB+CD=AD+CB. Its characteristics are Two compounds swap components. [0003] The essence of the cyanidation reaction is: sodium cyanide + sodium chloroacetate → sodium cyanoacetate + sodium chloride, which is a kind of metathesis reaction. Belonging to salt + salt → new salt + salt. [0004] The cyanidation reaction is an exothermic reaction, and the heat must be removed as soon as possible during the process to ensure the stability of the reaction temperature. Industrial productio...
