    Abstract: The present invention is directed to a composition made by reactingA) an aldehyde of 1 to 12 carbon atoms or a reactive equivalent thereof; andB) at least one etheramine represented by the formula         R 2 [O(CH 2 CH(R)O) n ―R 1 ―NH 2 ] y      (I)wherein each n is a number from 0 to about 50; each R is selected from the group consisting of hydrogen, hydrocarbyl groups of 1 to about 16 carbon atoms, and mixtures thereof; each R 1 is selected from the group consisting of a hydrocarbylene group containing 2 to about 18 carbon atoms and a group represented by the formula         ―(R 6 N) p ―R 7 ―wherein both R 6 and R 7 are hydrocarbylene groups of about 3 to about 10 carbon atoms and p is a number from 1 to 4; y is 1, 2, or 3; and each R 2 is a hydrocarbyl group having a valence of y and containing 1 to about 50 carbon atoms when y is 1 and 1 to about 18 carbon atoms when y is 2 or 3; y is 1, 2, or 3; provided that when n is zero, y is 1.The reaction product can include a N-substituted perhydro-s-triazine represented by the formulaFuel additives containing these compositions are useful in reducing intake valve deposit and do not contribute to the increase in combustion chamber deposit in port fuel injected engines.
