Abstract
A method of preventing fouling and coke formation on the high temperature sections of hydrocarbon processing equipment in contact with a hydrocarbon fluid which comprises adding to the hydrocarbon fluid prior to its contact with the high temperature sections of such hydrocarbon processing equipment an effective amount of a compound having the formula: ##STR1## wherein Q is Z, or R with the proviso that two occurances of Q are Z, R is hydrogen, or a straight or branched alkyl group having from 1 to 7 carbon atoms, and only one or two occurances of R may be alkyl; PA1 Z is represented by the formula: ##STR2## wherein R.sub.2 and R.sub.3 are the same as R and only one or two occurances of each of R.sub.2 or R.sub.3 may be alkyl, and "n" is a whole number of from 1 to 9.
