specific Embodiment approach 1

[0021] Embodiment 1: The chemical name of the fluorescent cationic surfactant in this embodiment is N,N-dimethyl-N-alkyl-N-(N'-(5-quinolyl)aminoacylmethyl)halogenated Ammonium, the structural formula is:

[0022]

[0023] where R=C n h 2n+1 , n=8~22, X is a halogen.

specific Embodiment approach 2

[0024] Specific embodiment two: the preparation method of the fluorescent cationic surfactant described in specific embodiment one, carries out according to the following steps:

[0025] Dissolve 5-chloroacetamidoquinoline and alkyl tertiary amine in a molar ratio of 1:(0.5~6) in solvent I, raise the temperature to 80~150°C and stir for 8~50h to obtain the crude product; then, the crude product The solvent in is evaporated to obtain a solid product; the solid product is further recrystallized by solvent II to obtain a fluorescent cationic surfactant.

specific Embodiment approach 3

[0026] Specific embodiment three: the difference between this embodiment and specific embodiment two is that the alkyl tertiary amine is N,N-dimethyl-octylamine, N,N-dimethyl-decylamine, N,N- Dimethyl-dodecylamine, N,N-dimethyl-tetradecylamine, N,N-dimethyl-hexadecylamine, N,N-dimethyl-octadecylamine, N,N-dimethyl Base-eicosylamine or N,N-dimethyl-eicosylamine; others are the same as in the second embodiment.

Abstract

The invention discloses a fluorescent cationic surface active agent and a preparation method and application thereof and relates to the cationic surface active agent and the preparation method and application thereof. The technical problems that an existing cationic surface active agent is single in function and performance is not regulated easily are solved. The chemical name of the fluorescent cationic surface active agent is N,N-dimethyl-N-alkyl-N-(N'-(5-quinolyl) aminoacyl methyl) ammonium halide, and the structural formula is shown in the description, wherein R is CnH2n+1, n is 8-22, and X is halogen. The preparation method comprises the steps that 5-chloracetyl-aminoquinoline and alkyl tertiary amine are dissolved in a solvent, heating and stirring are carried out, a coarse product is obtained, the solvent in the coarse product evaporates, and a solid product is obtained; furthermore, recrystallization is carried out on the solid product, and the fluorescent cationic surface active agent is obtained. The fluorescent cationic surface active agent can serve as a pH value indicator for a solution.

Description

technical field [0001] The present invention relates to cationic surfactant and its preparation method and application. Background technique [0002] Due to its high surface activity, excellent adsorption and bactericidal properties, cationic surfactants have been widely used in many fields such as cosmetics, sterilization, pharmaceuticals, and petrochemicals. Due to the extensive needs of modern society, a large amount of cationic surfactants are used in the world every year, which not only consumes a lot of chemical raw materials, but also causes a great burden on the natural environment. The functions of existing surfactants are wetting, penetrating, cleaning, dispersing, emulsifying, solubilizing, etc., and have a single function. Designing and synthesizing multifunctional surfactants with new structures can reduce material consumption and environmental pollution. Contents of the invention [0003] The present invention aims to solve the technical problem that the exi...
