  • Patent number: 10774058
    Abstract: A process for preparing D-glucaro-6,3-lactone from a salt of D-glucaric acid is provided.

  • Patent number: 9120736
    Abstract: The invention relates to a method for producing compositions containing unsaturated compounds, wherein (A) one or more unsaturated monocarboxylic acids having 10 to 24 C-atoms or esters of said monocarboxylic acids and optionally (B) one or more compounds having at least one C?C double bond (wherein the compounds (B) are different from the compounds (A)) are subjected to a tandem isomerization/metathesis reaction sequence in the presence of a palladium catalyst and a ruthenium catalyst, providing that the palladium catalysts used are compounds that contain at least one structural element Pd—P(R1R2R3), wherein the radicals R1 to R3, independently of one another, each comprise 2 to 10 C-atoms, which may be aliphatic, alicyclic, aromatic or heterocyclic respectively, providing that at least one of the radicals R1 to R3 contains a beta-hydrogen, wherein the palladium catalyst is used as such or is produced in situ, providing that the method is carried out in the absence of substances that have a pKa value of 3 or
