Abstract

The invention belongs to the field of amino acid surfactants, in particular to a high-efficiency continuous reaction device for amino acid surfactants, comprising a liquid separation tower, a pipeline synthesis reactor, and a pipeline neutralization reactor; the pipeline synthesis reactor is vertically arranged on the The middle part of the liquid separation tower, and communicated with the liquid separation tower; the pipe synthesis reactor is provided with a raw material inlet far away from the end of the liquid separation tower, and is provided with an acid inlet near the end of the liquid separation tower; The pipeline neutralization reactor communicates with the upper outlet of the liquid separation tower, and an alkali inlet is provided in the middle thereof. And disclosed its reaction method, the process route is simple, the reaction time is greatly shortened, and the whole synthesis reaction can realize continuous material input and product output, which can greatly improve production efficiency, improve reaction uniformity, and reduce side effects. Product yield, improve product quality.

Description

technical field [0001] The invention belongs to the field of amino acid surfactants, and in particular relates to a high-efficiency continuous reaction device and method for amino acid surfactants. Background technique [0002] Amino acid surfactants have good surface activity, bubble performance and cleaning performance, as well as high skin mildness and environmental friendliness. At present, they are mostly used in high-end daily chemical products. In addition, they are widely used in construction, medicine, minerals, petroleum, etc. The industry also has broad application prospects. [0003] In the prior art, amino acid surfactants are synthesized by batch reaction, and the specific process is as follows: adding liquid caustic soda, acyl chloride, amino acid and other raw materials required for the reaction into the reaction kettle for reaction; after the reaction is completed, the materials are transferred to the liquid separation kettle and add hydrochloric acid for l...
