    摘要: An object of the present invention is to provide an amino composition which provides, when used as a curing agent for epoxy resin, a long pot life and an excellent appearance of a coating film to an epoxy resin composition without deteriorating the reactivity of the composition. The amino composition is obtained by addition reaction of diamine such as metaxylylenediamine and 1,3-bis (aminomethyl) cyclohexane and styrene, wherein the content of the diamine is less than 15% by weight based upon the total weight of the amino composition and the content of 1-addition product of having one phenethyl group is 50 to 100% by weight based upon the total weight of amino compound(s) obtained by the addition reaction.

    摘要: This invention relates to an improved process for the preparation of cyclohexylamines wherein an aromatic amine is contacted with hydrogen in the presence of a hydrogenation catalyst. The improvement resides in utilizing a hydrogenation catalyst comprised of rhodium metal, utilizing a dialkyl ether solvent, and effecting delay addition of the aromatic diamine to the reaction medium.

    摘要: THE ISOMER RATIO IN A NON-EQUILIBRATED MIXTURE OF THE CIS AND TRANS ISOMERS OF A C6-C14 CYCLOALKYLANEBIS(METHYLAMINE9 SUCH AS 1,4-CYCLOHEXNEBIS(METHYLAMINE) CAN BE CONVENIENTLY ALTERED BY CONTACTING THE MIXTURE AT 175*290*C. WITH HYDROGEN IN THE PRESENCE OF A HYDROGENATION CATALYST AND AMMONIA. A HIGH YEILD OF ONE OF SUCH ISOMERS CAN BE OBTAINED BY SIMILARLY CONTACTING A MIXTURE OF SUCH ISOMERS WHEREIN THE RATIO OF SAID ONE ISOMER TO THE OTHER OF SAID ISOMERS IS LOWER THAN THE CORRESPONDING EQUILBRIUM RATIO OF SUCH ISOMERS, SELECTIVELY SEPARATING SAID ONE ISOMER FROM THE CONTACTED MIXTURE AND RECYCLING THE RESIDUAL MIXTURE FOR MORE OF SUCH CONTACTING.

    摘要: The method for producing trans-rich-1,4-bis(aminomethyl)cyclohexane includes blending 1,4-bis(aminomethyl)cyclohexane with an alkali metal compound and XDA and heating the mixture to isomerize 1,4-bis(aminomethyl)cyclohexane so that the trans isomer content relative to the cis/trans isomers in total is more than 70 mass %, and purifying the isomerized 1,4-bis(aminomethyl)cyclohexane by distillation after the isomerization step. The alkali metal compound is at least one compound selected from the group consisting of alkali metal hydride, alkali metal amide, and alkyl alkali metal. In the isomerization step, 0.01 mol or more and less than 4 mol of XDA is blended relative to 100 mol of 1,4-bis(aminomethyl)cyclohexane, a dimer produced from one molecular of 1,4-bis(aminomethyl)cyclohexane and one molecular of XDA, and a trimer produced from two molecules of 1,4-bis(aminomethyl)cyclohexane and one molecular of XDA are produced, and the dimer content is 5 mass % or more and less than 75 mass % relative to the dimer and trimer in total.
