Description

General description

2-(tert-Butylamino)ethanol (TBAE) is an alkanolamine. Its dissociation constant has been evaluated at several temperatures. It is a sterically hindered amine and is a useful chemical absorbent for the selective absorption of hydrogen sulfide in the presence of carbon dioxide. The physical solubility of hydrogen sulfide in aqueous solutions of TBAE neutralized with hydrochloric acid has been tested. The obtained solubility data was correlated using the van-Krevelen-Hoftijzer method.

Application

2-(tert-Butylamino)ethanol may be used in the synthesis of 3-tert-butyl-2,2-diphenyl-1,3-oxazaborolidine.
