ABSTRACT:
Gums and inorganic corrosion byproducts occurring in distilled petroleum fractions may be dispersed and resulting fouling controlled by adding to the petroleum distillate an effective dispersing amount of a monosubtituted alkylphenol polyethylenepolyamine-formaldehyde resin, such resins having a weight average molecular weight of from about 1,000 to about 10,000, and an alkyl substituent containing from about 4 to about 24 carbon atoms, which alkyl substituent may be a linear or branched.
