ABSTRACT N-alkane-N-alkanolamines are prepared by (a) reacting an N-alXane-N-alkanolamine having more N-alkanolamine moieties than the product compound, with a haloalkane; (b) reacting the product of step (a) with a strong base; and (c) deprotonating the product of step (b). The process of the inven- tion produces relatively pure compounds in high yield, from low-value starting materials. The compounds pro- duced by the invention are useful for the absorption of sulfur compounds from gases produced by the com- bustion of sulfur-containing hydrocarbon materials. 32,542-F
