Alcohol amines mainly include ethanolamine, isopropanolamine, DEIPA, TIPA, etc., which are important basic chemical raw materials. The molecular structure of these substances contains alcohol and amine functional groups, and has the chemical properties of alcohols and amines. It exhibits very useful coordination in many synthetic applications, reacts with acids to form a cool, and reacts with hydrazine to form a amide-based compound. Because of their greater polarity, these molecules can be used as a raw material for surfactants, as well as fiber industrial refining agents, antistatic agents, dyeing aids, and fiber wetting agents. It can also be used in the preparation of synthetic detergents, cosmetics, lubricating oils, cutting oils, plasticizers, emulsifiers, etc.
Surfactants are one of the most widely used fields for alcohol amines, and are widely used in household chemicals, petrochemicals, and cement industries. For example, ethanolamines are mainly used as moisturizers in cosmetics or reacted with lauric acid as an emulsifier and dispersant in cosmetics. The use of alkylalkanols to react stably with long-chain fatty acids to form surface-active soaps has important commercial applicability. Used as an emulsifying additive in textiles, lubricants, polishes, detergents, pesticides and personal care products such as hand lotions, shaving creams and shampoos. Surfactant Alkyl alcohol amine soaps are typically made from stearic acid for cleaning and scrubbing textiles. When combined with chlorinated solvents, these soaps become wetting agents. Alkyl alcohol amine soap can be added to mineral oil to make lubricated emulsified oil, petroleum water demulsifier and oil emulsifier. Studies have shown that alcohol amine organic corrosion inhibitors have a good protective effect on metal materials in reinforced concrete. Moreover, the alcohol amine organic corrosion inhibitor has the characteristics of being non-toxic to the human environment, pollution-free, and excellent in resistance to chloride ion pitting. In the field of cement grinding aids, the use of alcohol amines is also very extensive. Since most of the alcohol amines are highly polar and the aqueous solution is alkaline, it can mix the metal ions in the cement and interact with the minerals. Usually, it is compounded with polyols, which can significantly improve the powder of cement clinker. Grinding efficiency can also improve the performance of cement. Other studies have found that triethanolamine and triisopropanolamine, both of which increase the specific surface area and the coefficient of wear of the cement. The accelerated hydration process of the grinding aid causes the cement setting time to be shortened slightly. The grinding aid contains a delay in the setting time, and has a retarding effect at the initial stage of hydration, which improves the performance of the slurry and the composition of the ingredients. The grinding agent improves the compressive strength of the cement, the effect of the grinding aid is obvious, the compressive strength is improved, and the compressive strength is improved.
