    摘要： A process for separating phenol obtained by the decomposition of cumene hydroperoxide from high boiling impurities, includes the following steps:a) feeding phenol rectification bottoms comprising phenol, acetophenone, cumylphenol, alpha-methylstyrene dimers and high boiler residues to a first phenol freeing distillation column A;b) feeding concentrated bottoms with substantially reduced phenol content from column A to a second residue concentration distillation column B;c) withdrawing a stream rich in compounds boiling between phenol and residue, particularly cumylphenol, from said column B from a point below the feed and returning at least a portion of said stream to said column A at a point above the feed;d) recovering overheads from column A comprising at least 95 weight percent phenol; ande) recovering acetophenone-rich overheads from column B comprising at least 70 weight percent acetophenone.

    摘要： Compounds of the formula h WHEREIN Z and Z'' are hydroxy and Y and Y'' are H, -COCH3, or COOR'' (R'' being an alkyl group) are used to prepare compounds of the formula AND THERAPEUTICALLY ACCEPTABLE SALTS, ESTERS AND AMIDES THEREOF, WHEREIN R1, R2, R3, R4, R5 and R6 are the same or different and each is H or halogen, lower alkyl, hydroxy, lower alkoxy, substituted lower alkyl or substituted lower alkoxy, and X is a saturated or unsaturated, substituted or unsubstituted, straight or branched polymethylene chain which may be interrupted by one or more carbocyclic rings or oxygen-containing heterocyclic rings, oxygen atoms or carbonyl groups. The latter compounds are useful as inhibitors of certain antigen-antibody reactions, being particularly useful for the relief and prophylaxis of asthma.
