Abstract

A method for preparing 3-rosin amino-2-hydroxypropyl dimethyl benzyl ammonium chloride is a method for preparing a cationic active agent containing a rosin amine structure, belonging to the aspect of surfactant chemistry in the forest chemical field. At a temperature of between 10 and 150 DEG C, an acid-binding agent compounded by sodium carbonate, potassium carbonate, calcium carbonate, sodium bicarbonate, potassium bicarbonate, potassium hydroxide, sodium hydroxide, triethylamine, tripropyl amine and tributyl amine is loaded on a carrier consisting of aluminum oxide, silica gel and active carbon to form a solid which is used as a catalyst for catalyzing the reaction of rosin amine and quaternizing agent consisting of epoxy propyl dimethyl benzyl ammonium chloride and 3-chlorin-2-hydroxypropyl dimethyl benzyl ammonium chloride for 1 to 50 hours, and then the reactants are subjected to centrifugation or filtration, exsolution and composite solvent recrystallization to form a wet material of the 3-rosin amino-2-hydroxypropyl dimethyl benzyl ammonium chloride; and the wet material is dried for 1.0 to 48.0 hours at a temperature between 10 and 120 DEG C at a vacuum degree of 0.01 to 0.1MPa to form a product of the 3-rosin amino-2-hydroxypropyl dimethyl benzyl ammonium chloride mass percentage of which is more than 90 percent.

Description

technical field [0001] The method for preparing 3-rosinamino-2-hydroxypropyl dimethyl benzyl ammonium chloride involved in the present invention is a novel method for preparing cations containing rosin amine structure in the field of forestry chemical industry in the field of surfactant chemistry. Surfactant 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, ...
