| 摘要 |
The present invention provides a process for the alkylation of isoalkanes with olefins using sulfonated polymer catalysts, where the catalyst has a moisture content of less than about 1.0%, and a catalyst useful in such process. Preferred catalysts include sulfonated macroporous crosslinked vinylaromatic polymers and sulfonated carbonaceous adsorbent polymers having surface areas greater than about 400 square meters per gram. The process is useful for the synthesis of branched alkanes which may be used in high-octane gasolines, e.g., trimethylpentanes from isobutane and butenes. |
