Factory Supply Surfactant 1-Amino-2-Propanol CAS 78-96-6
Preparation
The propylene oxide and ammonia water with 95wt % concentration were fed into the mixer by a metering pump according to the ratio of molar ratio 1:1.0, and the temperature in the mixer was controlled to 0℃ and the pressure to 3.0MPa; The mixed liquid is continuously passed into the micro-channel reactor, and the material reacts in the channel of the reaction section of the reactor at a temperature of 60℃ and a pressure of 3.0MPa. After staying for 0.1S, the material enters the cooling section of the micro-channel reactor for rapid cooling to terminate the reaction. The outlet temperature is 0℃ and the retention time is 2S. The specific cooling speed is controlled at about 1800-2000℃/min. After removing the low boiling matter through the gas stripping column, the product 1-amino-2-propanol with the content of 99.2% was obtained. In this embodiment, the microchannel reactor is specifically made of stainless steel, where the inner diameter of the microchannel is 0.05mm and the length of the microchannel is 0.8m.
chemical property
Colorless transparent liquid.It is optically active and liquid at room temperature. Soluble in water and ethanol.
Application
Amino-2-propanol can be used as surfactant, fiber refining agent, antistatic agent, dyeing agent, fiber wetting agent, also can be used as synthetic detergent, cosmetics lubricating oil, cutting oil antioxidant, plasticizer, emulsifier and solvent preparation.
Amino-2-propanol has the following uses:
(1) The reaction with fatty acids to produce fatty acid isopropanolamide (alkyl isopropanolamide) and ester, because of its excellent foaming property, foam stability and the ability to dissolve grease, it can be used as an industrial synthetic detergent.
(2) The product obtained with thioglycolic acid can be used as a cosmetic substrate.
(3) Because of good hygroscopic properties and weak alkalinity, it can be used as raw materials for surfactants, refining agents, antistatic agents, dyeing AIDS and fiber wetting agents in the fiber industry.
(4) Its phosphate and nitrite can be used as antioxidants for various lubricants and cutting oils.
(5) The reaction products with various acids and high fat ketones can be used as plasticizers, emulsifiers and solvents. Isopropanolamine mixtures have a particularly strong ability to dissolve hydrocarbons, and a stable emulsion can be obtained by mixing kerosene, halogenated hydrocarbons, naphtha, etc., with isopropanolamine (4%) and oleic acid (15%) in water. The salt produced with long chain fatty acids can be used as the emulsifier of vinyl acetate resin, and the emulsion has good stability and stable color.
