[Chemical Knowledge]：What are the role and uses of isopropanolamine?

Read： 1019 Time：29months ago Source：

isopropanolamine is a white crystalline solid with weak basicity. Normal temperature is liquid. Soluble in water and ethanol. It has optical rotation. Normal temperature is liquid. Soluble in water and ethanol, the aqueous solution is alkaline, can react with acid to form esters, and react with acid halides to form amide-based compounds. It can be made by the reaction of propylene oxide and ammonia. After mixing propylene oxide with ammonia, it is preheated for addition reaction, and the resulting mixture is deaminated, dehydrated, decompressed distillation, and rectified to obtain the finished product. If the ratio of propylene oxide to ammonia is adjusted during the reaction, different proportions of isopropanolamine, diisopropanolamine and triisopropanolamine can be prepared.

Seven functions and uses

of isopropanolamine 1. Used as surfactant raw material and fiber industry refining agent, antistatic agent, dyeing aid and fiber wetting agent, etc

2. Used as surfactant, rubber vulcanization accelerator and solvent

3. The reaction with fatty acids produces fatty acid isopropanolamide (alkyl isopropanolamide) and ester, which are used as industrial synthetic detergents.

4. The product obtained from thioglycolic acid can be used as a cosmetic matrix.

5. Used as antioxidant for various lubricating oils and cutting oils.

6. The reaction products with various acids and higher fatty ketones can be used as plasticizers, emulsifiers and solvents.

7. The salt generated from long-chain fatty acids can be used as emulsifier of vinyl acetate resin. The emulsion has good stability and stable color.
