Abstract

The present invention is directed to a composition made by reacting A) an aldehyde of 1 to 12 carbon atoms or a reactive equivalent thereof; and B) at least one etheramine represented by the formula EQU R.sup.2 O(CH.sub.2 CH(R)O).sub.n --R.sup.1 --NH.sub.2 !.sub.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.sup.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 ##STR1## wherein both R.sup.6 and R.sup.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.sup.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 formula ##STR2## Fuel additives containing these compositions are useful in reducing intake valve deposit and do not contribute to the increa…
