摘要 |
An alkylating process is disclosed, according to which aromatic and alkylaromatic compounds, phenol and phenol derivatives are alkylated with olefins containing from 2 to 4 carbon atoms. The process is carried out in the presence of Beta zeolite as the catalyst. Beta zeolite is used as such, or modified by means of the isomorphous replacement of aluminum by boron, gallium or iron. In particular, this process is useful for preparing cumene. |
