THE STUDY OF INFLUENCE OF WATER ON THE CATALYTIC PROPERTIES OF CHLOROALUMINATE IONIC LIQUID COMPOSITION [BMIM]Cl-AlCl <sub>3</sub> IN THE REACTION ALKILATION OF ISOBUTANE BY BUTYLENES
The article are presented the results of studies of the effect of water on the pattern formation of isoalkanes alkylation reaction of isobutane by butylenes in the presence ionic liquid of the composition[BMIM]Cl-AlCl <sub>3</sub>. It is founded that when the concentration water in feed up to 10 ppm the selectivity of octanes isomers in alkylate gets 60% wt. and more highest. It is discovered, that increasing content of water in the alkylation feed contributes to lower selectivity due to side reactions of cracking and disproportionation. When the water content in feed has 1000-ppm yield on missed butene in the alkylation reaction in the presence of synthesized catalyst contains 2.4 g / g, which indicates the occurrence of the «superalkylation». It is discussed regularities of the mechanism of the alkylation reaction of isobutane with butenes, which contributed to produce products of cracking and disproportion based on experimental data.
