Technical triethanolamine, triethanolamine, triethanolamine
We offer triethanolamine. Triethanolamine is used in the production of polymer materials, cosmetology, textile auxiliary substances, surfactants, production of lubricating and cooling liquids, in pharmaceuticals, etc.
The most common method of obtaining triethanolamine at the present time is its synthesis in the composition of a mixture with mono- and diethanolamines. Synthesis of ethanolamines in industry is carried out based on ethylene oxide and ammonia. There are a number of methods that allow you to vary the ratio of target products. Individual triethanolamine is obtained after rectification of the reaction mixture, which is associated with a number of technological difficulties and energy costs. Triethanolamine obtained by this technology, as a rule, has a high color index, which makes it difficult to use in a number of areas or requires additional processing to decolorize it. In addition, the mixture of ethanolamines obtained by these methods contains triethanolamine in an amount not exceeding 20%(//tractor-service.com)
There is also a method for obtaining triethanolamine by oxyethylation of mono- or diethanolamine or their anhydrous mixtures at a temperature not higher than 50°C. The method makes it possible to exclude the stage of vacuum reaction run-up, however, it uses pre-synthesized mono- and diethanolamines isolated from the reaction mixture as starting materials.
Selective methods for obtaining triethanolamine by oxyethylation of mono- and diethanolamine in the presence of water have been developed. The disadvantage of known methods is the need for preliminary synthesis of ethanolamines.
