摘要：

Kinetics of partial oxidation of acetone in the presence of Ti2 (rutile, anatase) as a heterogeneous catalyst has been studied. Optimization of kinetic parameters has been carried out. It has been found that in the case of rutile, oxidation affords predominantly AcOH, while for anatase the main product is acetol, CH3COCH2OH. Reaction mechanism has been considered. It has been shown that different selectivities of rutile and anatase result from the dissimilarity of reaction mechanisms with these two modifications of TiO2.
