ABSTRACT:
The present invention relates to an organopolysiloxane compound having at least one group having the formula ##STR1## and at least one group having its formula selected from --R.sup.3 --C.sub.6 H.sub.5 or --R.sub.3 --O--C.sub.6 H.sub.5 per molecule wherein R.sup.3 is a divalent hydrocarbon group having from 1 to 20 carbon atoms, R.sup.4 is hydrogen, an alkyl group, an aryl group, or an acyl group, d has a value of 0 to 150, e has a value of 0 to 150, with the proviso that the value of d+e is at least one. The organopolysiloxane compounds of this invention reduce the amount of foam in the hydrocarbon fuel, especially in diesel fuels and jet fuels. The organopolysiloxane compound acts as a foam control agent which displays consistent compatibility and miscibility with additives which are frequently present in hydrocarbon fuels.
