Abstract

The invention discloses a preparation method of octadecylamine polyoxyethylene ether. The preparation method comprises the following steps: introducing nitrogen into a reaction kettle; adding part ofoctadecylamine into the reaction kettle; starting a chemical pump; adding part of ethylene oxide in an atomized state into the reaction kettle; starting a stirring device; adjusting the material flowrate of the chemical pump; adding potassium hydroxide and the rest of octadecyl fatty amine into the reaction kettle; adding part of ethylene oxide in an atomized state into the reaction kettle; and keeping the temperature of the reaction kettle for 30 min, cooling and discharging. According to the preparation method, materials circularly flow in the reaction kettle, the mixing uniformity degree of the materials is improved, sufficient mixing of the materials is guaranteed, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of chemical product production, in particular to a preparation method of octadecyl fatty amine polyoxyethylene ether. Background technique [0002] At present, the preparation method of octadecyl fatty amine polyoxyethylene ether adopts a one-step stirring method: it is prepared by polymerization in a stirred reactor with octadecyl fatty amine and ethylene oxide, and the catalyzer is potassium hydroxide. In this method, the polymerization reaction of octadecyl fatty amine and ethylene oxide is carried out inside the material, the polymerization reaction space is small, the flow of the material in the kettle is poor, and the stratification phenomenon is serious. The polymerization reaction is greatly affected by the material, and the reaction is incomplete. Thoroughly, the quality of the finished product is poor. Contents of the invention [0003] (1) Purpose of the invention [0004] In order to solve the technica...
