  • Process for obtention of highly-lineal, adjustable-isomery monoalkylated aromatic compounds
    Patent number: 8237001
    Abstract: The present invention refers to a procedure for obtaining a linear monoalkylaromatic compound, with adjustable 2-phenyl isomer content and an extremely low sulphonation color, in which a catalytic system is used based on highly stable and active solid catalysts and with a high selectivity for linear monoalkylaromatic compounds.
    Type: Grant
    Filed: December 4, 2007
    Date of Patent: August 7, 2012
    Assignee: Cepsa Quimica, S.A.
    Inventors: José Luis Berna Tejero, José Luis Goncalvez De Almeida
  • Process to obtain a highly soluble linear alkylbenzene sulfonate
    Patent number: 8158819
    Abstract: The present invention refers to a process to obtain a highly soluble linear alkylbenzene sulfonate (LAS). Specifically it comprises the addition, prior or after sulfonation of linear alkylbenzene and/or neutralization of linear alkylbenzene sulfonic acid of an hydrotropic composition. It also refers to a hydrotropic composition, to a highly soluble linear alkylbenzene sulfonate, to the use of the hydrotropic composition for making said linear alkylbenzene sulfonate highly soluble and to a cleaning composition comprising said linear alkylbenzene sulfonate.

  • Catalytic transalkylation of dialkyl benzenes
    Patent number: 8148592
    Abstract: The present invention relates to a method for performing catalytic transalkylation between long-chain dialkyl benzenes and benzene in order to obtain monoalkyl benzenes. As dialkyl benzene source, this method employs the by-products of a method for alkylation of benzene with linear C9-C16 monoolefins.
