  • Patent number: 9174891
    Abstract: The process of producing an alkylbenzene compound from the alkylation of an aromatic compound with an acyclic monoolefin is an exothermic process. A process for maintaining a relatively constant temperature improves the process and allows for controlling the yields. The process includes recycling a compound through the reactor that is relatively inert, but will moderate the exotherm, while maintaining the 2-phenyl content of the final alkylbenzene product.

  • Publication number: 20090306445
    Abstract: The invention relates to a method for extracting styrene, having a polymerisation quality, from pyrolysis benzol fractions containing styrene by means of extractive distillation. The pyrolysis benzol fraction is separated in a separating wall column in a C8-core fraction, a C7 fraction and a C9+-fraction, the obtained C8-core fraction is subjected to selective hydrogenation of the phenylacetylene C8H6 which it contains. Subsequently, the obtained C8-fraction undergoes extractive-distillative separation in a styrene fraction and a fraction which is low in styrene.

  • Publication number: 20090156872
    Abstract: The present invention relates to methods for accelerating the trans-cis isomerization of 1,2-diphenylethylene analogues by using photocatalyst. According to this invention, in the presence of polypyridyl platinum(II) complex with catalytic dosage, a solution containing trans-1,2-diphenylethylene analogues or mixture of cis- and trans-1,2-diphenylethylene analogues is irradiated by visible light to prepare product of cis-1,2-diphenylethylene analogues or product predominantly being cis-1,2-diphenylethylene analogues under inert gas atmosphere. This method has the advantages of fast reaction, high performance, easy separation of reaction system and recycle of the polypyridyl platinum (II) complexes.

  • Publication number: 20090137855
    Abstract: A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene and one or more alkanes are introduced into said first alkylation reaction zone. The operating conditions, e.g. temperature and pressure, of the first alkylation reaction zone are controlled effective to cause the alkylatable aromatic compound to be partly in the vapor phase and partly in the liquid phase, and the ratio of the volume of liquid to the volume of vapor of the feed in each zone to be from about 0.1 to about 10. The aromatic compound and the alkene of the feed are reacted in the presence of the alkylation catalyst to form an effluent comprising the alkylaromatic compound, unreacted alkylatable aromatic compound, any unreacted alkene and the alkane.

    Abstract: Integrated, energy efficient process for making detergent range alkylbenzenes, heavies coproduced during the alkylation of benzene with olefin using a solid, acidic catalyst are transalkylated. Spent benzene from regeneration of the solid, acidic catalyst used for alkylation provides at least about 50 percent of the benzene provided for the transalkylation. The integrated processes thus reduce the load on the benzene distillation assembly used in the alkylbenzene refining system.
