  • Patent number: 11058660
    Abstract: A method of healing an external wound involves applying an external wound-healing agent to an external wound, or bringing the external wound-healing agent applied to a substrate into contact with an external wound, wherein the external wound-healing agent includes, as an active ingredient, at least one compound of a glycerol alkyl ester represented by defined Formula (I) or a diglycerol alkyl ester represented by defined Formula (II). In a further embodiment, the method involves bringing a fiber aggregate or a film into contact with an external wound, wherein the fiber aggregate or the film each includes a thermoplastic resin and at least one compound of the glycerol alkyl ester or the diglycerol alkyl ester.

  • Patent number: 9969675
    Abstract: A method for producing trans-bis(aminomethyl)cyclohexane includes a trans-isomerization step in which cis-dicyanocyclohexane is isomerized into trans-dicyanocyclohexane by heating dicyanocyclohexane containing cis-dicyanocyclohexane in the presence of a tar component produced by distillation of dicyanocyclohexane; and an aminomethylation step in which trans-dicyanocyclohexane produced by the trans-isomerization step is allowed to contact with hydrogen to produce trans-bis(aminomethyl)cyclohexane.
