This paper presents the results of selective purification of oil distillates with a viscosity of 7.5 mm2/s and 18 mm2/s at [Formula: see text]C, as well as a mixture of these oil distillates obtained by compounding at various ratios using an ionic liquid based on diethylamine and formic acid as an extractant acid. The conditions for the ionic liquid dearomatization of the indicated oil distillates were determined by studying the influence of various factors on the selective purification process. Many parameters are set for the objects of research. The values of physicochemical parameters determined under various conditions are presented in the tables.

Efficient CO2 conversion by formate dehydrogenase is limited by the low CO2 concentrations that can be reached in traditional buffers. The use of ionic liquids was proposed as a manner to increase CO2 concentration in the reaction system. It has been found, however, that the required cofactor (NADH) heavily degraded during the enzymatic reaction and that acidity was the main reason. Acidity, indeed, resulted in reduction of the conversion of CO2 into formic acid and contributed to overestimate the amount of formic acid produced when the progression of the reaction was followed by a decrease in NADH absorbance (method N). Stability of NADH and the mechanism of NADH degradation was investigated by UV, NMR and by DFT calculations. It was found that by selecting neutral–basic ionic liquids and by adjusting the concentration of the ionic liquid in the buffer, the concentration of NADH can be maintained in the reaction system with little loss. Conversion of CO2 to methanol in BmimBF4 (67.1%) was more than twice as compared with the conversion attained by the enzymatic reaction in phosphate buffer (24.3%).
