Abstract

See full text

Disclosed are cloud point depressants and methods of making and using them. The disclosed cloud point depressants comprise copolymers of an unsaturated anhydride polymerized with alkyl α-olefins and then contacted with a phenyl alkyl alcohol or alkyl phenol alkoxylate, fatty alcohol and primary or secondary fatty amine to provide a cloud depressant reaction product. When the disclosed reaction products are added to middle distillate fuels or blends of middle distillate fuels with biodiesel, the cloud point depressants inhibit the precipitation of waxes and/or biowaxes in the fuels and the fuels exhibit reduced precipitation, gelling, and/or crystallization when subjected to low or cold temperatures.
