Abstract

A cleaning agent and its production are disclosed. The cleaning agent consists of AEO-9, AEO-7, acetyl chloride, propionyl chloride, NaHCO3 and stabilizer. The process is carried out by injecting mixture of AEO-9 and AEO-7 into reactor, heating, dripping into mixed liquor of acetyl chloride and propionyl chloride, raising temperature, ageing reacting, decompressing, degassing, lowering temperature, adding into stabilizer, regulating pH value by NaHCO3 and naturally lowering temperature. The branched-chains of various reactants are inter-penetrated and connected to form into high-molecular weight multi-polymer with multifunctional group and long-chain structure. It's clean and efficient.

Description

technical field [0001] The invention belongs to the technical field of fine chemical industry of industrial chemicals, in particular to a nonionic surface active cleaning agent, and also relates to a preparation method of the product. Background technique [0002] The development of high-efficiency, environmentally friendly, and room-temperature detergents has always been the direction of scientific research in the detergent industry. In recent years, some developed countries have invested tens of millions of dollars in scientific research funds for the research and development of this project. Especially industrial cleaning, such as large military weapons, large and medium-sized machinery and equipment, aviation, navigation, metallurgy, mining, chemical industry, electromechanical and other industries, small to daily car repair, air conditioning cleaning, equipment maintenance and various civilian metal and non-metal objects, Cleaning and decontamination of sanitary utensi...
