  • Patent number: 10781159
    Abstract: A hydrogenation method for increasing the yield of cyclohexane-1,4-dicarboxylic acid diisooctyl ester is provided. The hydrogenation method uses a hydrogenating reaction tank, which is equipped with a hollow-shaft gas-introducing mixer having air-extracting, air-exhausting and mixing functions, to allow hydrogen gas to be uniformly dispersed in a reaction solution. A ruthenium-on-alumina (Ru/Al2O3) hydrogenation catalyst can be used for carrying out a hydrogenation reaction under gentle conditions. Therefore, the hydrogenation catalyst can be used in a reduced amount, the risk of side reaction(s) can be reduced, and the yield of cyclohexane-1,4-dicarboxylic acid diisooctyl ester can reach at least 99% with a cis isomer proportion of at least 85.0%.

  • Patent number: 8653296
    Abstract: A method for preparing esters of cyclohexane polycarboxylic acids from esters of benzene polycarboxylic acids makes improvement to hydrogenation of esters of benzene polycarboxylic acids by using a reaction tank having a gas-introducing mixer capable of extracting and exhausting air and stirring to hydrogenate an ester of a benzene polycarboxylic acids into an ester of a cyclohexane polycarboxylic acid in the presence of a hydrogenation catalyst; resulted in that the method advantageously minimizes the operational pressure for hydrogenating esters of benzene polycarboxylic acids and significantly lowers the reaction temperature for hydrogenation while effectively improving the yield of esters of cyclohexane polycarboxylic acids made from the esters of the benzene polycarboxylic acids.

  • Publication number: 20130338393
    Abstract: Provided is a method for producing an alicyclic carboxylic acid by hydrogenating an aromatic ring of an aromatic carboxylic acid, which comprises using a catalyst containing ruthenium and palladium as a catalyst, and also provided is a co-supported ruthenium-palladium catalyst in which ruthenium and palladium are present in a form of particles containing both the ruthenium and palladium on a surface of a support. A catalyst has been developed which uses a relatively inexpensive noble metal, ruthenium, which has an activity equivalent to that of a rhodium catalyst, and which does not undergo decrease in activity as observed in a rhodium catalyst, and thereby an industrially simple method for producing an alicyclic carboxylic acid has been established.
