  • Patent number: 10544081
    Abstract: A process for preparing an aromatic compound or compounds where at least one mandelic group —CHOH—COOH is described, comprising a reaction for condensation of at least one aromatic compound with glyoxylic acid or derivatives thereof, wherein said condensation reaction is carried out substantially in the absence of any acid or any base added to the reaction medium. The condensation reaction is followed by an oxidation reaction in order to obtain aromatic aldehyde.

  • Publication number: 20190292131
    Abstract: Method (M) for the preparation of an end compound from an internal ketone, said method comprising: —synthesizing the internal ketone by a process (P) for the decarboxylative ketonization of a fatty acid, a fatty acid derivative or a mixture thereof in a liquid phase with a metal compound as catalyst in the substantial absence of added solvent, wherein the fatty acid, fatty acid derivative or mixture thereof is added in sequential steps, the first step taking place at a temperature sequentially at a temperature from 100° C. to 270° C., —causing the internal ketone to react in accordance with a single or multiple chemical reaction scheme involving at least one reagent other than the internal ketone, wherein at least one product of the chemical reaction scheme is the end compound that is not further caused to be chemically converted into another compound.

  • Publication number: 20190256766
    Abstract: Methods of acidizing a subterranean formation penetrated by a wellbore that include the steps of (a) injecting into the wellbore at a pressure below subterranean formation fracturing pressure a treatment fluid having a first viscosity and including an aqueous acid and a gelling agent selected from the group consisting of Formulas I-XI and combinations thereof; (b) forming at least one void in the subterranean formation with the treatment fluid; and (c) allowing the treatment fluid to attain a second viscosity that is greater than the first viscosity.
