  • Method for producing hydroxycarboxylic acid derivative
    Patent number: 9115075
    Abstract: To provide a method for the production of a hydroxycarboxylic acid derivative, by which a hydroxycarboxylic acid derivative, which can be reused in various applications, can be obtained from a polyamide at a high yield without consuming a large amount of energy. A method for the production of a hydroxycarboxylic acid derivative, which is characterized by including allowing an alcohol in a supercritical state to act on a polyamide in the presence of a carboxylic acid derivative to depolymerize the polyamide to obtain the hydroxycarboxylic acid derivative.

  • PROCESS FOR PRODUCING 6-HYDROXYCAPROIC ESTER AND PROCESS FOR PRODUCING TRIALKYLAMINE
    Publication number: 20090124824
    Abstract: A process for producing a 6-hydroxycarpoic ester and a process for producing a trialkylamine in both of which nylon-6, ?-caprolactam, which is a monomer therefor, etc. are used as a raw material. The processes are intended to make nylon-6 wastes reusable in various applications without consuming a large quantity of energy. The process for producing a 6-hydroxycarpoic ester and process for producing a trialkylamine are characterized by reacting amide compounds basically comprising ?-caprolactam with an alcohol in a supercritical state to obtain a 6-hydroxycarpoic ester and a trialkylamine.
