  • Furoic acid preparation method
    Patent number: 10961212
    Abstract: A method is for the preparation of furoic acid or of one of its derivatives of formula (I): in which R1, R2, R3 and R4 represent, independently of each other, a hydrogen atom, a linear or branched C1-C6 alkyl group, a —C(?O)—H group or a —COOH group, by heterogeneous catalytic oxidation of furfural or a derivative thereof of formula (II). The oxidation is carried out in the presence of a supported catalyst based on gold nanoparticles, and in a non-alkaline aqueous medium. A composition useful in the method includes at least furfural and supported gold nanoparticles.
    Type: Grant
    Filed: March 16, 2017
    Date of Patent: March 30, 2021

  • Phenalene-1-one derivatives, method for producing same and use thereof
    Patent number: 9302004
    Abstract: The present disclosure relates to a compound of formula (1): where R1 through R8, which can be identical or different from each other, each are selected from of the group comprising hydrogen and the radical —(CH2)k—X, where k is a whole number from 1 to 20 and where X is an organic radical comprising a) at least one neutral, protonizable nitrogen atom and/or b) at least one positively charged nitrogen atom, under the provision that at least 1 radical R1 through R8 is not hydrogen. The invention further relates to the production and use of said compound.
