Diethanolamine
Chemical properties of this product is a liquid, m.p. 27 ~ 30 ℃, 217 ℃ / b.p. 19 kpa, n20D 1.4770, relative density 1.097, f.p. 137 ℃.
It is also called diethanolamine, which is the middle body of the herbicide glyphosate.
Used as a purification agent for gases, as well as synthetic and organic materials
Use as analytical reagent, gas chromatographic fixed fluid, softener and lubricant, also used in organic synthesis
USES diethanolamine mainly used as the acid gas such as CO2, H2S and SO2 absorption agent, nonionic surface active agent, emulsifier, polishing agent, industrial gas purifying agent, lubricant.
Used as a thickening agent in shampoo and light detergents, as a softening agent in synthetic fibers and leather production.
Diethanolamine and 70% sulfuric acid, the dehydration ring is formed in the form of a phyrin (1, 4-oxyazohexane).
Morpholine and diethanolamine are intermediates in organic synthesis, for example, can be used to produce some optical bleaching agent in textile industry, morpholine fatty acid salt can be used as a preservative, morpholine can also be used to produce the central depressants pholcodine or as solvent.
Diethanolamine in analytical chemistry as a reagent in the gas phase chromatography stationary liquid, can be selectively retention and separation of alcohol, glycol, amine, pyridine, quinoline, piperazine, mercaptan, sulfur ether and water.
USES acid gas absorber, oxidizing agent, organic synthesis, softening and lubricant.
Gas chromatographic stationary liquid (highest use temperature 60 ℃, the solvent of methanol), selective retention and separation of alcohol, glycol, amine, pyridine, quinoline, piperazine, mercaptan, sulfur ether and water.
The method of production is diethylamine, which is produced by ethylene oxide and ammonia, and also with an ethanolamine and triethanolamine.
Epoxy ethane, ammonia water into the reactor, the reaction temperature 30 to 40 ℃, 70.9 304 kpa pressure, carries on the condensation reaction to generate one, two, triethanolamine mixture, under the 90-120 ℃ after dehydration concentrate into three decompression distillation to vacuum distillation, according to different boiling point capture fractions, was a purity of 99%, however, ethanolamine, diethanolamine and triethanolamine finished products.
In the process of the reaction, the ratio of ethylene oxide to ethylene glycol was increased, and the yield of two and triethanolamine was increased.
Production method of the preparation method is to use liquid ammonia and ethylene oxide at 132 ℃ under pressure reaction, reaction got a ethanolamine, diethanolamine, triethanolamine, can also use a ethanol amine as the raw material preparation of diethanolamine.
