Mushrush, George W. published the artcileChemical basis of middle-distillate fuel instability – interactive effects of selected nitrogen heterocycles with organic acids and bases in a shale-derived diesel fuel, Formula: C5H5NO3S, the publication is Oil Shale Symposium Proceedings (1991), 74-81, database is CAplus.

Fuel-instability reactions with increasing time in storage usually are defined in terms of the formation of deleterious products, such as filterable sediment and peroxides. These detrimental products of long-term storage continue to be a problem in the utilization of middle-distillate fuels. Gravimetric stability tests have been carried out at 80° by using 2 model N heterocycles: 2,5-dimethylpyrrole (DMP) and 3-methylindole (3-MI) in an otherwise stable shale-derived diesel fuel. Potential interactive effects for these N heterocycles in this stable middle-distillate fuel have been described by the presence of organic acid and base co-dopants. Organic acid co-dopants included hexanoic acid, acetic acid, dodecylbenzene sulfonic acid, and p-toluene sulfonic acid; organic bases employed included tri-n-butylamine, N,N-di-Me aniline, and 4-dimethylamino pyridine. Co-dopants were selected on the number of polar species present in a shale-derived diesel fuel. The fuel matrix containing the co-dopants, 2,5-dimethylpyrrole and dodecylbenzene sulfonic acid, generated the largest quantity of filterable sediment yet observed in any of the stability tests. Simple organic amines exerted only minor interactive effects, usually an increase in filterable sediment of 5-15%. However, the diamine species, 4-dimethylamino pyridine, interacted in a strongly pos. fashion to generate increased amounts of sediment. Hydroperoxide levels were monitored for each reaction mixture Co-dopants had a drastic beneficial effect on observed hydroperoxide concentration
