  • Patent number: 5210353
    Abstract: A process is provided for transaralkylating a class of starting compounds comprised of aryl-substituted lower alkanes and aryl-substituted fused alkylene ring compounds to produce derivatives of such compounds wherein benzyl substituents thereof have different alkyl substituents compared to the starting compounds. The process is carried out by admixing such a starting compound with a lower alkyl-substituted aromatic compound under liquid phase conditions in the presence of a catalytically effective amount of a Friedel-Crafts catalyst. The process makes possible new and economical routes for synthesizing desired lower alkyl-substituted benzyl group containing compounds, such as 2,2-di(lower alkyl-substituted) phenyl propanes and 1,3,3-trimethyl-1-(lower alkyl-substituted)-phenyl indans. Thus, there is provided a three-step process for making dixylylpropane from alpha methyl styrene and also a two-step process for making 1,3,3,6-tetramethyl-1-o-xylyl indan from alpha-4-dimethyl styrene.

  • Patent number: 5171423
    Abstract: A catalytic cracking process is provided for cost effectively separating and stripping hydrocarbon from catalyst while limiting the occurrence of undesired catalytic overcracking and thermal cracking reactions. The process includes the steps of contacting feed with catalyst, grossly separating the larger coked catalyst particles from the hydrocarbon, disengaging the smaller coked catalyst fines from the hydrocarbon, removing volatile hydrocarbon from the grossly separated and disengaged catalyst, and recycling the volatile hydrocarbon back to the gross separating step. The disengager step includes the steps of dampening the flow of grossly separated hydrocarbon and internally cyclone separating the smaller catalyst fines from the hydrocarbon product.

  • Patent number: 5159028
    Abstract: The invention describes a novel process for the preparation of polycarbonate and/or polyarylate block copolymers with poly(aryl ethers). The process is comprised of the steps:(a) the reaction of a dihydroxy-terminated poly(aryl ether) oligomer with a high molecular weight polycarbonate, or a high molecular weight polyarylate, or a high molecular weight poly(arylate-carbonate) to yield a block copolymer; followed by(b) the coupling of the material obtained in step (a) to the required molecular weight, using a diaryl ester of carbonic acid or of a dicarboxylic acid.Both steps are performed in the presence of a catalyst. The copolymerizations can be run in bulk under vacuum in a single or twin screw extruder. Using the above conditions high molecular weight, high quality block copolymers having a combination of excellent properties are obtained in a matter of minutes.

  • Patent number: 5157184
    Abstract: Catalyzed vapor-phase processes are taught for the oxidative dehydrogenation of a lower-alkyl-monosubstituted ethylbenzene to a lower-alkyl-monosubstituted styrene. Barium pyrophosphate and the pyrophosphate-containing calcination product of KFe.sub.3 H.sub.14 (PO.sub.4).sub.8.nH.sub.2 O, n running between about 1 to about 4, are shown to effectively catalyze these dehydrogenations at a low enough temperature such that very little cracking of the lower alkyl group occurs which gives superior conversions and selectivities to the corresponding styrenes and lengthened catalyst lifetime. An improved method of preparation of KFe.sub.3 H.sub.14 (PO.sub.4).nH.sub.2 O is described as well as the new material which is essentially KFe.sub.3 H.sub.6 (P.sub.2 O.sub.7).sub.4.

  • Patent number: 5155216
    Abstract: Polynucleotides are labeled with chemiluminescent acridine esters or luminescent lanthanides. Labelling is preferably carried out by incorporating a functional group into a nucleotide or polynucleotide at the C4 position of the pyrimidine portion or the C6 position of the purine portion and bonding a chemiluminescent acridine ester or a luminescent lanthanide to the functional group. The labeled polynucleotides are useful for direct detection of homologous polynucleotide sequences.
