Abstract
A lauric amide surfactant and a synthetic method thereof are provided. The inventive lauric amide surfactant has the structural formula as above. The synthetic method includes the following steps: synthesizing a lauric amide surfactant intermediate from lauric acid and hydroxyethylethylene diamine as raw materials, and then performing amphoteric reaction by 'chloroacetic acid process' to obtain the lauric amide surfactant. The invention is novel in the direct synthesis of amide surfactants by vacuum amphoteric method without ring closing reactions. The inventive lauric amide surfactant has good forming performance, low irritation, and excellent compounding, washing, wetting and penetrating performance; and can be used in baby and adult shampoos, synthetic fibers, antistatic agents in plastic industry, lanolin amide softening agents, dye levelers in textile industry, corrosion inhibitors and foaming agents.
Description
[technical field]: the invention belongs to surfactant and preparing technical field thereof.
[background technology]: dodecoic acid acidamide surfactant involved in the present invention is a kind of novel surfactant, and its performance and carboxylic acid type imidazoline amophoteric surface active agent compare favourably.
The imidazoline type amphoteric surfactant of aliphatic group has performances such as excellent washing, wetting, foaming and dispersion
[1,2], excitant is very low
[3], low toxicity or nontoxic
[4], antistatic
[5], antibiotic
[6], environmentally friendly.
Amphoteric surfactant is pressed its textural classification: (1) imidazoline amophoteric surface active agent (2) beet alkali ampholytic surface active agent (3) amino acid surfactant (4) lecithin class surfactant.Wherein lecithin class surfactant is natural surfactant, and remaining is artificial synthetic
[7]
Amphoteric surfactant is the later class of exploitation in surfactant.Nineteen thirty-seven, United States Patent (USP) just had report.Du pont company had been developed this compounds in 1940, and reported first betaine be amphoteric surfactant.It is amphoteric surfactant that German Adolf Schmitz in 1948 has studied amino acid, and begins to use.The U.S. has just produced more than 20 kind of amphoteric surfactant commodity in the eighties in 20th century.Phase late 1980s, the amphoteric surfactant of the U.S. increases with the annual growth of 5%-6%, considerably beyond the annual average rate of increase of industrial surface activity agent 2% at that time.Entered since the nineties in 20th century, the amphoteric surfactant of developed country is still in steady development, and the output of the amphoteric surfactant of developed country accounts for the 2%-3% of surfactant total output, and the kind number of present Japanese amphoteric surfactant is about 200
[8]
Domesticly after the seventies in 20th century, begin amphoteric surfactant is conducted a research, have few products to throw people market at present, but kind and quantity are all few, so in amphoteric surface the live research and the application facet of agent, China still is in the starting stage.In China's amphoteric surfactant kind, the still non-betaine type of output maximum does not belong to, and what occupy next is amphoteric imidazoline.The ascendant trend of amido propyl betaine type is very fast in the betaine, and alkyl betaine is the atrophy gesture.Amphoteric imidazoline is not smooth in the development of China, by the leading position of the eighties in 20th century, drops to the subordinate status of the nineties in 20th century, and it is also descending to ratio of cation imidazoline, is to be lower than 50% weak tendency
[9]
[summary of the invention]: the object of the invention provides a kind of acid amide type surfactant, particularly dodecoic acid acidamide surfactant and synthetic method thereof.
The present invention is on the basis of summing up former achievements, and with laurate, AEEA and monoxone are raw material, without the ring process that reaches a standard, adopt the vacuum-direct synthesizing amide type of amphoterisation method surfactant innovatively.
Dodecoic acid acidamide surfactant of the present invention, its component is:
The synthetic route of dodecoic acid acidamide surfactant of the present invention is:
