On March 9, 2016, Yu, Kun; Reichard, Mikayla C.; Dai, Ning published an article.Synthetic Route of 2160-93-2 The title of the article was Nitrosamine Formation in the Desorber of Tertiary Alkanolamine-Based Carbon Dioxide Capture Systems. And the article contained the following:
Tertiary amines are being considered as absorption solvents for post-ombustion CO2 capture, but their potential to form harmful byproducts nitrosamines is yet to be evaluated. This study examined the factors affecting the formation of nitrosamines from tertiary alkanolamines under simulated desorber conditions and the effects of amine structural characteristics. Total nitrosamine formation from tertiary alkanolamine was determined to be 1st-order with respect to nitrite concentration and the absorbed CO2, but was 0-order with respect to amine concentration in the range of 0.5-2.5M. Tertiary alkanolamines formed less nitrosamine than their secondary amine analogs. For tertiary alkanolamines with the same number of 2-hydroxyethyl groups, smaller steric hindrance resulted in more nitrosamine formation and higher yields based on nitrite consumption. The anal. of specific nitrosamines revealed that the cleavage of 2-hydroxyethyl group was preferred over demethylation, but comparable to de-ethylation. Reaction pathways were proposed to account for the exptl. observations. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2
