    摘要: Monoisopropylphenyl/phenyl phosphate containing mixtures are prepared by, (1) alkylating phenol with propylene to C.sub.3 /.phi. ratio of less than 0.30 with a p-toluene sulfonic acid catalyst, (2) removing unreacted phenol as distillate to yield a distilland having a C.sub.3 /.phi. ratio above 0.3 and thereafter, (3) phosphorylating the distilland to yield a triaryl phosphate mixture having a reduced 2,6-diisopropylphenyl phosphate content.

    摘要: There is disclosed a process for the racemization of amino acids and derivatives thereof. The racemization process of the present invention uses an aromatic aldehyde-containing polymer made from the reaction of a hydroxyaromatic aldehyde with a chloromethylated vinylbenzene polymer under reaction conditions to form an aromatic aldehyde-containing polymer wherein the aldehydic moiety is linked to the polymer through an ether linkage. There is also disclosed a process for the production of the racemization catalyst. Another embodiment of the invention comprises a process for the promotion of the racemization reaction wherein a tertiary amine-containing resin is used as a promoting agent.

    摘要: Aryloxyaluminoxanes containing the unit ##STR1## where R is unsubstituted or substituted aryl, such as phenyl or naphthyl, are useful as a cocatalysts in Ziegler-Natta and Kaminsky-type olefin polymerization catalysts. They can be formed by reaction of a source of water with an organoaluminum compound containing the desired aryloxy moiety or by reaction of preformed aluminoxane with an organic compound, such as a phenol, containing such a moiety.

    摘要: An improved method for the synthesis of omega-unsaturated carboxylic acids is disclosed which precludes double bond migration or hydrogenation in order to prepare a high purity product necessary for high resolution in forming a resist by electron beam microlithography. This result can be obtained by a coupling reaction between a Grignard reagent of an unsaturated organochloride compound as defined in the application with a halo magnesium salt of a long chain organic acid.
