Abstract
AbstractThe novel and more safe method for propene acetoxylation has been developed. The reaction is conducted in the liquid environment of acetic acid, which is also the one of the substrates for this process, in the presence of palladium catalyst supported onto activated carbon. The influence of acetic acid concentration, temperature and pretreatment of the carbon catalyst support on the selectivity of transformation to allyl acetate and propene conversion has been investigated. The influence of the parameters has been described using the following factors: the selectivity of transformation to allyl acetate in relation to propene consumed and degree of propene conversion. Preparation of the catalyst and its characteristics has been described. Catalysts were prepared by wet impregnation method and pelletized activated carbon was used as a support. Prepared catalysts were analysed using XRD, SEM-EDX and UV-VIS DRS methods. Carbon support was pretreated before impregnation due to the literature reports. Thus the final catalyst samples were different from one another in terms of quantity and degree of dispersion of active phase on the support surface. Activity of catalyst samples has been tested in propene acetoxylation as the one of reaction parameters.
