The effect of high molecular weight carboxylate ligands as compared to naphthenate ligands on the effectiveness of transition metals as additives for reducing soot particulates was studied in the combustion of diesel fuel and distillate fuel oil by use of a laboratory scale burner. A mechanism involving pseudoheterogenerous catalytic reactions is proposed. A simple system to evaluate fuel additives by burning only a few milliliters of oil was designed, developed, and used. Polybutene with an average molecular weight of 920 was the raw material in this study. The polymer was oxidized with KMnO4 to the corresponding acid from whose potassium salt the transition metal-polymer complex obtained. Special treatments were required during the synthesis because of unique viscosity and solubility properties exhibited by the polymer. The oxidation was carried out in the presence of dicyclohexane 18-crown-6 ether as a phase transfer catalyst.
