Description

N, N-dimethyl-N[3-(sugared amide group)] propyl group-N-alkyl brometo de amonio and synthetic method thereof
Technical field
The present invention relates to a kind of glycosyl amide quaternary surfactant and synthetic method thereof, relate in particular to a kind of N, N-dimethyl-N[3-(sugared amide group)] propyl group-N-alkyl brometo de amonio and synthetic method thereof.
Background technology
In recent years, along with the pay attention to day by day of people to environmental problem, the preparation environmentally-friendly surfactant causes more and more that also people pay close attention to.Not only cost of material is cheap, aboundresources to produce tensio-active agent with carbohydrate, and products obtained therefrom is gentle, nontoxic, excellent property, environment compatibility are good, is one of focus of 21 century people concern.Gluconolactone and lactobionic acid are prepared by renewable resources starch; have low price, environmental protection, be easy to carry out with alkylamine the advantages such as amine ester reaction; and this reaction need not the hydroxyl on the sugar is carried out loaded down with trivial details, expensive protection; it is low that reaction has temperature; reaction conversion ratio is high; without advantages such as side reaction generations, meet very much the characteristics of atom economic reaction.Thereby, take Gluconolactone and lactobionic acid as the glycosyl amide type tensio-active agent of raw material production, have good development space.
Sugar-based Quaternary Ammonium Salt Surfactants combines the high efficiency of mildness and the quaternary ammonium salt cationic surfactant of glycosyl surfactant active, make its mildness with nonionogenic tenside, hypotoxicity, low irritant, have bactericidal properties, static resistance and the anti-hard water of cats product concurrently, also having the not available energy of general cats product and the good compatibility of anion surfactant, is a kind of multifunctional type tensio-active agent.
The present synthetic method of Sugar-based Quaternary Ammonium Salt Surfactants mainly is to be raw material with glucose or alkyl glycoside, first quaternized again glucosides or first glucosidesization more quaternised method synthesize.The human low-grade tertiary amines (Trimethylamine 99, triethylamine, tripropyl amine) such as Kenneth B. Moser generate cationic reagent with epichlorohydrin reaction, and then generate the glycosyl quaternary ammonium salt with the alkyl glycoside reaction.The people such as Manfred Weuthen develop first alkyl glycoside and epichlorohydrin reaction, generate chloro glucosides intermediate, and then generate the glycosyl quaternary ammonium salt with reactive tertiary amine.The main deficiency of these two kinds of methods is that the active difference of each hydroxyl is little in the alkyl glycoside, reacts uncertain where, reacts unbalanced, often occurs polysubstituted; The human glucose such as John J. Tsai react with chloro-hydrin(e) first, obtain the chloro glucosides, carry out quaterisation with senior tertiary amine again, obtain target product.Not only need catalyzer in this reaction, and in the quaterisation process because the intermiscibility of chloro glucosides and senior tertiary amine is bad, and the steric hindrance of glucose is very large in addition, speed of reaction is very slow.And all be the product that combines with ehter bond mostly in the Sugar-based Quaternary Ammonium Salt Surfactants of reporting at present, the Sugar-based Quaternary Ammonium Salt Surfactants that combines with amido linkage has no report.Amido linkage is similar to the peptide bond in the protein, can have better consistency with skin, can give hair, skin natural gloss, and make it soft and moist.
With Gluconolactone or lactobionic acid and N, N-dimethyl-1,3-propylene diamine reaction generates N, N-dimethyl-N[3-(sugared amide group) with bromoalkane generation quaterisation again] synthetic method and the product structure of propyl group-this class novel surfactant of N-alkyl brometo de amonio there is not yet report.
Summary of the invention
The purpose of this invention is to provide a kind of Gluconolactone or lactobionic acid elder generation and N of utilizing; N-dimethyl-1; the reaction of 3-propylene diamine generates N; N-dimethyl-N '-sugared acyl group-1; 3-propylene diamine intermediate; again with the N of bromoalkane generation quaterisation preparation, N-dimethyl-N[3-(sugared amide group)] propyl group-N-alkyl brometo de amonio and synthetic method thereof.
N provided by the invention, N-dimethyl-N[3-(sugared amide group)] general structure of propyl group-N-alkyl brometo de amonio is as follows:
Wherein: R is C 8-C 14Long chain hydrocarbon groups, glycosyl is monosaccharide groups or diglycosyl.
Reaction scheme following (take Gluconolactone as example):
