The invention relates to the technical field of reaction devices, and in particular relates to improved preparation equipment for a cationic surfactant. The equipment is characterized in that a material inlet pipe is sequentially provided with a material inlet valve and a circulation valve along the material inlet direction; one end of a circulation pipeline is connected with the top of a buffer tank, and the other end of the circulation pipeline is connected to the part, located between the material inlet valve and the circulation valve, of the material inlet pipe; the circulation pipeline issequentially provided with a second control valve, a Roots vacuum pump and a first control valve from the bottom to the top; a material pipe located between a chloromethane device and the material inlet pipe is provided with a third control valve; the bottom of the buffer tank is connected with one end of a liquid return pipe, and the other end of the liquid return pipe is connected with the part, located between the circulation valve and the circulation pipeline, of the material inlet pipe; and the buffer tank is provided with a fourth control valve. Compared with the prior art, the equipment provided by the invention has low improvement costs and a simple structure, can ensure a sufficient reaction of chloromethane with monohexadecylamine, reduce a theoretical usage amount of the chloromethane, and greatly shorten the reaction time.
Description
technical field [0001] The invention relates to the technical field of reaction devices, in particular to an improved manufacturing equipment for cationic surfactants. Background technique [0002] The theoretical reaction chemical equation of cetyltrimethylammonium chloride is as follows: [0003] C 16 h 33 NCH 32 +CH 3 Cl→[C 16 h 33 NCH3 3 ] + Cl - [0004] see figure 1 , the existing production of cetyltrimethylammonium chloride is to put the raw material monohexadecyl tertiary amine and pure water into the enamel reaction kettle 1 through the suction pipe 5, after being heated to the reaction temperature, the methyl chloride device 2 The control valve 2-1 door, that is, the valve on the methyl chloride cylinder, is opened, and then the stirring motor 3 is turned on to drive the stirring paddle 4 to rotate, and the discharge valve 1-1 at the bottom of the enamel reaction kettle 1 is opened, and the methyl chloride is started to flow, and according to the reacti...
