Low Co2

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%).

Pyridinium Cations

Two kinds of task-specific ionic liquids (Ils) composed of imidazolinium or pyridinium cations with a carboxy group and hydrogensulfate as counterion have been synthesised and their application in oxidation of olefins has been studied. The carbonyl compounds were obtained from the oxidation of chain olefins, and 1,2-cycloalkandiols were obtained from cycloalkenes in the novel oxidation systems which are easily manipulated. The products can be easily isolated from the reaction system and the ILs can readily be recovered and reused.
