Petroleumacids was removed from straight-run diesel distillate through chemical reaction and extraction under moderate conditions using an alkaline complex solution.
The structures and compositions of the purified petroleumacids were characterized by using infra-red spectrum, nuclear magnetic resonance and negative-ion electrospray ionization mass spectrum.
