Synthesis of derivatives of alkylamino alkyloxy propanol structures by N-alkylation, acylation, and nitration. Application as fuel additives

Polyfunctional compounds were prepared by alkylation, acylation, and nitration of hydroxyl and amine functions of the following alkanolamine ether structures: (di)alkylamino alkyloxy propanol, hydroxy alkyloxy (di)alkylamino propanol, and their dimer compounds. The resulting compounds were characterized by conventional spectroscopic methods, and complete nuclear magnetic resonance data are given. These reactions extented the application of these propanic compounds to use as multipurpose fuel additives. In particular, they enhance phase stability and improve the cetane number in ethanol‐diesel fuel blends.
