    摘要: A method for cleaving a bisphenol which comprises: (1) a cleavage step comprising feeding a mixture of a bisphenol and derivatives of chroman and flavan which are by-produced during the production of a bisphenol to a cleavage reactor and effecting cleavage reactions in the presence of a basic or acidic catalyst at 150 to 260 DEG C under a reduced pressure of 300 mmHg or less, (2) a distillation step comprising feeding the products of the cleavage reactions to a distillation column in a gaseous state and conducting a distillation at 130 to 200 DEG C under a reduced pressure of 300 mmHg or less, and (3) a reflux step comprising condensing the distillate from the distillation step, recycling a part of the resultant condensate to the distillation step at a reflux ratio of 0.01 to 3 and drawing out the rest of the condensate to the outside of the system. The method can be employed for producing a product containing isopropenyl phenol and phenol with high purity.

    摘要: The present invention relates to novel specifically-­substituted phenyl compounds, especially substituted di- tert -butyl phenol derivatives, which are effective as anti-inflammatory, analgesic and/or antipyretic agents. These phenyl compounds are substituted with a low molecular weight alkyl chain which ter­minates in a specific unsaturated functional group. These un­saturated functionalities are -C=CH, C=CH₂, C=C=CH₂, and alde­hydes in the form of their acetals.
    The present invention further relates to pharmaceutical compositions which contain an anti-inflammatory agent of the present invention and a pharmaceutically-acceptable carrier.
    Finally, the present invention relates to methods for treating diseases characterized by inflammation, such as rheumatoid arthri­tis and osteoarthritis, in humans or lower animals. Such methods comprise administering to a human or lower animal in need of such treatment a safe and effective amount of an anti-inflammatory agent or composition of the present invention.

    摘要: An alkylated hydroxyl-containing aromatic compound is produced by isomerizing a normal alpha-olefin having from about 16 to about 30 carbon atoms in the presence of a first solid, acidic catalyst capable of inducing both olefin isomerization and skeletal isomerization to produce a mixture of isomerized olefin, then alkylating an hydroxyl-containing aromatic compound with the mixture of isomerized olefins in the presence of a second solid, acidic catalyst. The first solid, acidic catalyst can be SM-3, MAPO-11, SAPO-11, SSZ-32, ZSM-23, MAPO-39, SAPO-39, ZSM-22, SSZ-20, ZSM-35, SUZ-4, NU-23, NU-87, natural ferrierite or synthetic ferrierite. The second solid, acidic catalyst can be a sulfonic acid anionic ion exchange resin catalyst or an acidic clay.

    摘要: Meta-hydroxyphenylacetylenes are produced from phenyl-substituted ketal or acetal precursors. Using biotransformation processes, these precursors serve as substrates that are converted to cis-dihydrodiol intermediates. The cis-dihydrodiols can be converted chemically to the corresponding meta-substituted compounds, e.g., meta-substituted phenols, and then to m-hydroxyphenylacetylene, which is an intermediate needed to produce acetylene-terminated resins. The biotransformation step employs arene-2,3-dioxygenase in intra- or extra- cellular form.
