ABSTRACT:
Ester derivatives 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 [hydroxy-methyl] aminomethane (THAM) adducts or mixtures are oleaginous compositions which feature activity in gasoline as rust inhibitors and carburetor detergents; in automatic transmission fluids as friction modifiers and rust inhibitors; and, in automotive, industrial and lubricating oils as sludge dispersants, rust-inhibitors, friction modifiers and copper alloy corrosion inhibitors, the particular use depending on the molecular weight of the ester.
