Lauryl alcohol polyoxyethylene ether acetate and cleaning agent taking lauryl alcohol polyoxyethylene ether acetate as main component

Abstract

The invention discloses lauryl alcohol polyoxyethylene ether acetate. A preparation method comprises the following steps of: performing esterification reaction of lauryl alcohol polyoxyethylene and acetyl chloride under the conditions of microwave radiation and no solvent, wherein process conditions include: the ratio of raw materials is 1: 1.00-1.10, the microwave emissivity is 375W, and the reaction time is 5min; extracting a reaction product by chloroform, washing the obtained product for two times by using 5 percent sodium carbonate solution, drying the obtained product, and obtaining a lauryl alcohol polyoxyethylene ether acetate product through detection analysis; and then adding 8 to 10 percent of propylene glycol n-propyl ether, 4 to 5 percent of hydroxypropyl sodium cellulosate, 5 to 6 percent of sodium chloride and 45 to 50 percent of water into the product to obtain a non-ionic cleaning agent product by high-speed stirring. The product has special degreasing ability and excellent wettability, can be compatible with cationic and anionic surfactants, and has larger solubility in the water, which ensures that the product has broad application prospect.

Description

technical field [0001] The invention relates to an alcohol-based nonionic surfactant, in particular to a lauryl alcohol polyoxyethylene ether acetate and a cleaning agent mainly composed of it, belonging to the technical field of chemical auxiliaries. Background technique [0002] In the process of industrial production, all kinds of dirt will be produced in the equipment and pipelines of the production process, such as coking, oil dirt, scale, sediment, corrosive dirt, etc. These dirt usually lead to failure of equipment and pipelines, devices System production efficiency decreases, energy consumption increases, etc., and even safety accidents occur in severe cases. [0003] In recent years, with the rapid development of the new synthetic industry, new types of industrial dirt are also emerging, and their molecular structure is becoming more and more complex; in addition, the bonding mechanism and bonding form between industrial dirt and different washing objects often depe...

Problems solved by technology

People such as Gao Lixin in China once reported that a kind of surfactant was synthesized with carbon tetrachloride as a solvent -- lauryl alcohol polyoxyethylene ether phosphate (published in the 5th issue, the 30th volume, daily chemical industry magazine No. 63 in 2000 -66 pages), this reaction is carried out in the organic solvent carbon tetrachloride, not only can bring harm to the environment in the reaction process, also wasted resources and energy etc. simultaneously

People such as Dou Jianmin once reported to use polyoxyethylene lauryl ether and benzoyl chloride to react and synthesize polyoxyethylene lauryl ether benzoate (applying for a Chinese national invention patent, the patent number is: ZL 200610086679.6, and the publication number is CN1896046), which has Special degreasing ability and superior wettability, but the reaction time is long, it takes 3 hours, and the solubility of the product in water is not large, which brings certain problems to practical application
