  • 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.

  • 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.
