    Abstract: Carbonyl compounds (e.g. acetone and acetaldehyde) are often present as impurities in oxygenated organic liquids such as acetic acid made by the carbonylation of methanol or in phenol produced by the oxidation of cumene. These impurities can render petrochemical products unsuitable for long-term storage or otherwise adversely affect downstream processing operations. It has now been found that detrimental carbonyl impurities can be easily removed from oxygenated organic liquids by contact with resins having amine functional groups.

    Abstract: An etherification process combines an alkylation zone with a skeletal olefin isomerization zone in an arrangement that rejects isoalkanes and normal alkanes with only minor loss of valuable olefin isomers. The invention also provides a balanced feed to an alkylation zone for the production of high octane gasoline components. This invention can be used to provide ethers and gasoline boiling range alkylates from either C.sub.4 or C.sub.5 feedstocks. The invention fully utilizes all olefin isomers improve octane and vapor pressure charactristics of the gasoline components.

    Abstract: A process is disclosed for the simultaneous alkylation of light hydrocarbons to produce gasoline blending components and the etherification of an isoolefin to produce an ether. The etherification zone effluent stream contains normal olefins and isoparaffins consumed in an acid-catalyzed alkylation zone. The etherification zone effluent stream is separated in a fractionation column in a manner which provides a small amount of ether in the hydrocarbon-rich overhead stream. The presence of the ether in the acid-catalyst is beneficial to the alkylation reaction by providing a higher octane number product.

    Abstract: A process for the recovery of phenol from a reaction mixture resulting from the acid cleavage of cumene hydroperoxide is disclosed. Neutralization of the acidic reaction mixture is effected with sodium phenate--a product derived from the subsequent recovery of phenol and recycled to the neutralization process. The resulting mixture is further treated to effect an improved separation of the salt of neutralization therefrom.

    Abstract: The invention relates to a conversion process for making olefin(s) using a molecular sieve catalyst composition. More specifically, the invention is directed to a process for converting a feedstock comprising an oxygenate in the presence of a molecular sieve catalyst composition, wherein the air feed to the catalyst regenerator is free of or substantially free of metal salts. The air feed is preferably purified by passage through a rotary adsorbent contactor or adsorbent wheel.
