Abstract

The invention relates to an acetone cyanohydrin low-temperature reactor. The reactor comprises a barrel (11), a first end socket structure (12), a second end socket structure (13), a stirrer (14) and an outflow device (15), wherein the first end socket structure (12) and the second end socket structure (13) are arranged at two opposite ends of the barrel (11), the stirrer (14) is arranged in the barrel (11), and the outflow device (15) is arranged in the barrel (11); the stirrer (14) comprises an input pipe (141) and a nozzle (142) connected with the input pipe (141); the outflow device (15) comprises an output pipe (151) and a liquid outlet nozzle (152) connected with the output pipe (151); and the position of the liquid outlet nozzle (152) is higher than that of the nozzle (142). The reactor effectively improves the conversion rate of hydrocyanic acid.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an acetone cyanohydrin low-temperature reactor. Background technique [0002] Acetone cyanohydrin (ACH): (CH3)2C(OH)CN, colorless or brownish-yellow liquid, slightly bitter almond smell, widely used in civil, industrial, decoration, military and other fields. Because the acetone cyanohydrin molecule contains active hydroxyl and nitrile groups, a series of reactions such as hydrolysis, dehydration, alcoholysis, ammonolysis, and cyclization can occur, and many fine chemical products are derived, which are widely used in medicine, pesticides, food and feed additives , Coating additives and other industries. Acetone cyanohydrin is also an important chemical intermediate, the main purpose is to produce methyl methacrylate, and then make plexiglass; it can also be used to produce important initiator azobisisobutyronitrile and pesticides. As an important organic synthesis intermediate...
