  • Patent number: 9181145
    Abstract: The present invention relates to a process for the alkylation of an organic compound comprising: (a) providing a catalyst comprising one or more zeolitic materials having a BEA framework structure, wherein the BEA framework structure comprises YO2 and optionally comprises X2O3, wherein Y is a tetravalent element, and X is a trivalent element, (b) contacting the catalyst with one or more alkylatable organic compounds in the presence of one or more alkylating agents in one or more reactors for obtaining one or more alkylated organic compounds, wherein the one or more zeolitic materials is obtainable from a synthetic process which does not employ an organotemplate as structure directing agent.
