| Abstract: | The catalytic active phase (CAP) of a novel liquid catalyst for isobutane alkylation with butenes was investigated,the composition of the CAP was analysized.The components of the catalytic active phase were separated and examined by the methods of FTIR,UV and NMR etc..On the basis of these results,a reaction mechanism based on the formation of protonated heteropolyacid as an intial stage in the isobutane alkylation with butenes was postulated,which is in agreement with the experimental results.ActiveCompon |
