Title: Alkylene glycol esters of carboxylate half esters of 1-aza-3,7-dioxabicyclo[3.3.0] oct-5-yl methyl alcohols, their preparation and use as additives for gasoline and middle distillate fuels and lubricants

Abstract: Alkylene glycol esters of carboxylate half esters of 1-aza-3,7-dioxabicyclo[3.3.0] oct-5-yl methyl alcohols which are the reaction products of organic acid materials, preferably long chain dicarboxylic anhydrides such as octadecenyl and polyisobutenylsuccinic anhydrides and aldehyde/tris [hydroxymethyl] aminomethane (THAM) adducts or mixtures are friction reducing additives for liquid hydrocarbons, such as gasoline middle distillates and lubricants.
