cetane index

The effect of fuel oil on the environmental parameters of diesel fuel and the possibility of using it to reduce environmental pollution from road transport were investigated. It was established that fuel oil additives have a positive effect on the main parameters that can affect the ecology of diesel fuels and ensure their support according to Euro standards. The optimal concentrations of fuel oil additives for improving the environmental parameters of diesel fuel, such as density, viscosity, cetane index, boiling points of 10% and 50% fractions, were determined.

The features of adipic acid esterification with 1-butanol in the presence of aluminosilicates activated with sulfuric acid as a catalyst have been studied. The optimal process conditions have been determined. The influence of a heterogeneous catalyst nature on the esterification proceeding has been defined. Досліджено закономірності естерифікації адипінової кислоти 1-бутанолом у при- сутності активованих сульфатною кислотою алюмосилікатів як каталізаторів. Визначено оптимальні умови процесу. Встановлено вплив природи гетерогенного каталізатора на перебіг естерифікації.
