Abstract

The invention relates to cationic quaternary ammonium and a preparation method thereof. The structural formula of the cationic quaternary ammonium is shown in the specification. The preparation method of the cationic quaternary ammonium comprises the following steps that 1, epoxy chloropropane, polyol and an acid catalyst are placed into a reaction still, the molar ratio of the epoxy chloropropane to the polyol is 1.00-1.10:1, the reaction temperature is controlled to be 60-85 DEG C, the reaction time is 2-4 h, and unreacted epoxy chloropropane is removed in a vacuum mode; 2, the obtained product in the step 1 and tertiary amine conduct quaterisation reaction in a solvent, the molar ratio of the obtained product to the tertiary amine is 1.00-1.04:1, the pH value is 8-10, the reaction temperature is controlled to be 75-95 DEG C, the reaction time is 3-5 h, and the cationic quaternary ammonium is obtained. The cationic quaternary ammonium can achieve the function of cationic conditioner and humectants simultaneously, at the same time, the problem that the humectants cannot play a role in washing-off type daily wash supplies is solved, and a brand-new consumer sense experience is provided for the washing-off type daily wash supplies.

Description

technical field [0001] The invention relates to the technical field of chemicals and their synthesis, in particular to a cationic quaternary ammonium salt and a preparation method thereof. Background technique [0002] Cationic conditioning agents and moisturizing agents in daily chemical cleaning products are two separate substances, and they can provide cationic conditioning and moisturizing functions of daily chemical cleaning products only when used in synergy. [0003] In the prior art, it is difficult for the moisturizing agents of daily chemical cleaning products to play a role in wash-off products, because the moisturizing agents are easily soluble in water and are easily washed off during the washing process. and moisturizing chemicals. SUMMARY OF THE INVENTION [0004] Based on this, the object of the present invention is to provide a cationic quaternary ammonium salt with both cationic conditioning and moisturizing functions. [0005] The specific technical so...
