Problems solved by technology

[0009] The invention of a method for preparing 3-rosinamino-2-hydroxypropyltrimethylammonium chloride is mainly to solve the problems existing in the preparation method and process of the existing quaternary ammonium salt cationic surfactant containing rosinamine structure. There are many reaction steps, the process is more complicated, the conversion rate of rosin amine is not high, the content of quaternary ammonium salt in the product is not high, and the water solubility of the product is not very good due to the presence of more unreacted rosin amine in the product. Problems that affect the application performance of the product

Abstract

The invention relates to a method for preparing 3-abietylamine-2-hydroxypropyltrimethylammonium chloride, in particular to a method for preparing a cationic active agent with an abietylamine structure in respect of surface active agent in the filed of chemical processing of forest products. The method comprises the steps: at temperature lower than 10 DEG C to 150 DEG C, an acid binding agent combined by sodium carbonate, potassium carbonate, calcium carbonate, sodium bicarbonate, potassium bicarbonate, potassium hydroxide, sodium hydroxide, triethylamine, tripropyl amine and tributylamine is carried on a solid composed on a carrier consisting of aluminum oxide, silica gel and active carbon to serve as a catalyst and directly catalyze abietylamine to react with a quaternization reagent composed of epoxypropyl trimethyl ammonium chloride and 3-chlorin-2-hydroxypropyltrimethylammonium chloride for 1h to 50h; then centrifugation or filtering, desolution at normal pressure or pressure reduced and recrytallization of a compound solvent are carried out, thus obtaining a wet material of the 3-abietylamine-2-hydroxypropyltrimethylammonium chloride; the wet material is dried for 1.0h to 48.0h at temperature of 10 DEG C to 120 DEG C at a vacuum degree of 0.01MPa to 0.1MPa; and a 3-abietylamine-2-hydroxypropyltrimethylammonium chloride product with mass content higher than 90 percent is obtained.

Description

technical field [0001] A method for preparing 3-rosinamino-2-hydroxypropyltrimethylammonium chloride involved in the present invention is a novel method for preparing cationic surfactants containing rosinamine structure in the field of forestry chemical industry. dose method. Background technique [0002] Rosin is a renewable natural resource. As a chemical raw material, it also has the characteristics of abundant sources and low price. The main component of rosin is a resin acid with a three-membered phenanthrene ring structure composed of abietic acid, long-leaved abietic acid and neoabietic acid. Because there are not only carboxyl groups but also unsaturated carbon-carbon double bonds in the resin acid, the resin acid can be converted into rosin derivatives such as rosin amine and abietol through chemical modification. These rosin derivatives can be used to synthesize a series of products with similar structures to fatty acids, fatty amines, and fatty alcohol surfactan...
