CREATING THE BASIS OF NON-EXHAUSTIVE TECHNOLOGY OF CYCLOHEXAN OXIDATION

Cyclohexane oxidation is object of this research. One of the most problematic points of this process is low conversion of raw material and low selectivities for aim-products at conversions higher than 4%. One of the reasons for this is absence of modern effective catalytic systems that could increase mentioned indexes. One of the directions of solving these problems is the creation of a technology for the integrated use of the obtained oxidation products on the basis of the developed new effective catalytic systems, which will enable to increase the selectivity of the process.

Одержання бутиладипінату у присутності активованих алюмосилікатів

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.
