  • PROCESS FOR TREATING POLYESTER METHANOLYSIS DEPOLYMERIZATION PRODUCT STREAMS
    Publication number: 20230022664
    Abstract: Disclosed is a method for treating the product stream from a polyester methanolysis depolymerization process wherein the product stream includes dimethyl terephthalate and one or more side species selected from the group consisting of dimethyl phthalate, dimethyl isophthalate, bisphenol-A, an adipic acid diester and colorants. The method includes a) hydrogenating said dimethyl terephthalate to form one or more of dimethyl 1,4-cyclohexanedicarboxylate and 1,4-cyclohexanedimethanol; and (b) hydrogenating one or more of said one or more side species of said product stream. A method for depolymerization of polyester is also described.

  • Process for the preparation of 1,3-cyclohexanedimethanol from isophthalic acid
    Patent number: 8877984
    Abstract: Disclosed is a process for the preparation of 1,3-cyclohexanedimethanol from isophthalic acid. Isophthalic acid is esterified with (3-methylcyclohexyl)methanol and the isophthalate ester hydrogenated to 1,3-cyclohexanedimethanol in a 2-stage process. The (3-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. Also disclosed is a method for purifying and recovering the 1,3-cyclohexanedimethanol product.

  • Integrated process for the preparation of 1,4-cyclohexanedimethanol from terephthalic acid
    Patent number: 8766017
    Abstract: Disclosed is an integrated process for the preparation of 1,4-cyclohexanedimethanol from terephthalic acid. Terephthalic acid is esterified with (4-methylcyclohexyl)methanol and the terephthalate ester hydrogenated to 1,4-cyclohexanedimethanol in a 2-stage process. The (4-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. Also disclosed is a method for purifying and recovering the 1,4-cyclohexanedimethanol product.
