Easton, T; Thomas, B

A method is described for de-hazing distillate fuel which comprises adding to the fuel an organosiloxane having at least one quaternary ammonium substituted siloxane unit having the general formula R/sub a/ZSiO/sub (3-a)/2/ in which a has the value 1 or 2, each R is selected from the group consisting of substituted and unsubstituted hydrocarbon groups having up to 10 carbon atoms, provided that one R may be a hydroxyl group when a has the value 2, Z represents a quaternary ammonum group having the formula R'N/sup +/(R/sup 2/)/sub 3/X/sup -/ linked to the silicon atom of the siloxane unit, in which R' represents a divalent hydrocarbon group linking the silicon and nitrogen atoms, each R/sup 2/ represents an alkyl group having up to 20 carbon atoms and X/sup -/ represents a halogen ion, the distillate fuel containing up to about 0.1 percent by weight of water dispersed therein. The patent also describes a mixture consisting essentially of a distillate fuel and up to about 0.1 percent by weight of water based on the weight of the distillate fuel; with a de-hazing amount of an organosiloxane having at least one quaternary ammonium substituted siloxane unit.
