    Abstract: Low-color bisphenols may be produced by a reacting phenol with an aliphatic aldehyde or ketone in the presence of a strong-acid cation exchange resin acting as an acid catalyst for the reaction, and of a small amount, relative to the acid catalyst, of a weak-base anion exchange resin.

    Abstract: 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.
