Embodiment 1

[0034] Inhale the uniform liquid obtained after 165g N-coco-based propylene diamine melted by slight heat into a 1L reactor, and use N 2 Replace twice to remove air from the system. Under stirring conditions, the temperature was raised to 110°C, and then 110g of ethylene oxide gas was continuously introduced for the reaction. The pressure was controlled at 0.25MPa, the feeding time was 30 minutes, and the reaction temperature was controlled at 120°C. After the gas was passed, the reaction was obtained for 2 hours. The intermediate product N,N-cocoyl, hydroxyethyl-N',N'-dihydroxyethyl propylene diamine.

[0035] Put 38.1g of the product obtained in the above steps into a 500mL reactor, and add 0.30gNa 2 CO 3 As catalyst, 50g isopropanol as solvent, use N 2 Replace the air in the reactor twice, heat up to 70°C under agitation, and then continuously feed 11.6g of methyl chloride gas into the reactor for reaction. The feed time is 30 minutes, the reaction pressure is controlled at 0.2...

Embodiment 2

[0037] Inhale the uniform liquid obtained after 165g N-coco-based propylene diamine melted by slight heat into a 1L reactor, and use N 2 Replace twice to remove air from the system.

The pressure was controlled at 0.35MPa, the feeding time was 50 minutes, and the reaction temperature was controlled at 125°C. After the gas was passed, the reaction was reacted for 2.5h The intermediate product N,N-cocoyl, hydroxyethyl-N',N'-dihydroxyethyl propylene diamine is obtained.

[0038] Put 34.9g of the product obtained in the above steps into a 500mL reactor, and use 0.36gNa 2 CO 3 As the catalyst, 42.8g isopropanol as the solvent, use N 2 Replace the air in the reactor twice, heat up to 75°C under agitation, and then continuously feed 11.1g of methyl chloride gas into the reactor for reaction. The feed time is 40 minutes, the reaction pressure is controlled at ...

Embodiment 3

[0040] Inhale the uniform liquid obtained after 165g N-coco-based propylene diamine melted by slight heat into a 1L reactor, and use N 2 Replace twice to remove air from the system. Under stirring conditions, the temperature was raised to 120°C, and then 116g of ethylene oxide gas was continuously fed in for the reaction. The pressure was controlled at 0.4MPa, the feeding time was 50 minutes, and the reaction temperature was controlled at 130°C. After the gas was passed, the reaction was obtained for 3 hours. The intermediate product N,N-cocoyl, hydroxyethyl-N',N'-dihydroxyethyl propylene diamine.

[0041] Put 48.9g of the purified product obtained in the above steps into a 500mL reactor, and add 0.28gNa 2 CO 3 As the catalyst, 71.8g isopropanol as the solvent, use N 2 Replace the air in the reactor twice, heat up to 80°C under stirring conditions, and then continuously feed 17.0g of methyl chloride gas into the reactor for reaction. The feed time is 50 minutes, the reaction press...

Abstract

A kind of N, N, N-coco-hydroxyethyl-methyl-N', N', N'-dihydroxyethyl-methylpropylene diammonium chloride surfactant, its structural formula is as follows: wherein R is coconut oil base. The invention has the advantages of good surface activity and low surface tension in aqueous solution.

Description

Technical field [0001] The invention relates to a cationic surfactant and its preparation, in particular to N,N,N-cocoyl-hydroxyethyl-methyl-N',N',N'-dihydroxyethyl-methyl Propylene diammonium chloride surfactant and its preparation method. Background technique [0002] N-alkyl propylene diamine is an important type of intermediate, which is produced by larger aliphatic amine manufacturers abroad. Each manufacturer is responsible for simplifying the process, improving the economic benefits of products, deep processing of products, and the development and application of derivatives. A lot of work. However, in China, the development of N-alkylpropylene diamine has a history of only one to twenty years. The traditional synthesis process of primary amine and acrylonitrile is used, and the equipment is old stirred tank reactor. Mass trial production stage. [0003] N-alkyl propylene diamine is cationic and can be used to synthesize multifunctional surfactants such as betaine-amine ox...
