Embodiment 1

[0023] The preparation method of a kind of cationic quaternary ammonium salt of the present embodiment comprises the steps:

[0024] (1) Preparation of organic chlorides containing moisturizing functional groups

[0025] Add 1.00 mol of ethylene glycol and 1.55 g of sulfuric acid catalyst into a five-necked flask with stirring, thermometer, and condensing reflux, stir, and slowly add 1.00 mol of epichlorohydrin. After the addition is completed, maintain the temperature at 60°C. React The time is 2 hours, and the unreacted epichlorohydrin is removed in a vacuum to obtain an organic chloride containing a moisturizing functional group.

[0026] (2) Preparation of cationic quaternary ammonium salt conditioning moisturizer

[0027] Add 1.00mol of organic chloride with moisturizing functional groups, 1.00mol of dodecyl dimethyl tertiary amine, 555 grams of water, and sodium hydroxide to control pH8.0— 10.0, heated to 75°C, and maintained the reaction time for 3h, the cationic quat...

Embodiment 2

[0031] A kind of preparation method of cationic quaternary ammonium salt conditioning moisturizing agent of the present invention, comprises the following steps:

[0032] (1) Preparation of organic chlorides containing moisturizing functional groups

[0033] Add 1.00mol of propylene glycol and 2.33 grams of sulfuric acid catalyst in a five-necked flask with stirring, thermometer and condensing reflux, stir, slowly add 1.05mol of epichlorohydrin, maintain the temperature at 70°C after the addition is completed, and the reaction time is After 3 hours, the unreacted epichlorohydrin was removed under vacuum to obtain organic chlorides containing moisturizing functional groups.

[0034] (2) Preparation of cationic quaternary ammonium salt conditioning moisturizer

[0035] Add 1.02mol of organic chlorides with moisturizing functional groups, 1.00mol of myristamidopropyldimethyl tertiary amine, 688 grams of water, and sodium hydroxide to control pH8.0— 10.0, heated to 85°C, and mai...

Embodiment 3

[0039] A preparation method of a cationic quaternary ammonium salt conditioning moisturizer in this embodiment comprises the following steps:

[0040] (1) Preparation of organic chlorides containing moisturizing functional groups

[0041] Add 1.00 mol of glycerol and 2.33 grams of hydrochloric acid catalyst into a five-necked flask with stirring, thermometer, and condensing reflux device, stir, and slowly add 1.10 mol of epichlorohydrin. After the addition is completed, maintain the temperature at 85°C. React The time is 4 hours, and the unreacted epichlorohydrin is removed in vacuum to obtain an organic chloride containing a moisturizing functional group.

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 conditioners and moisturizers in daily chemical care products are two separate substances, and they can provide cationic conditioning and moisturizing functions of daily chemical care products only when they are used in conjunction. [0003] In the prior art, it is difficult for the moisturizer of daily chemical care products to play a role in the wash-off type products, because the moisturizer is easily soluble in water, and it is easy to be washed off during the washing process. Therefore, it is necessary to develop a and moisturizing chemicals. Contents of the invention [0004] Based on this, the purpose of the present invention is to provide a cationic quaternary ammonium salt with cationic conditioning and moisturizing functions. [0005] Th...
