Title:
ORGANIC AMINE COLLECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/131855
Kind Code:
A1
Abstract:
Provided is a method for collecting a compound represented by general formula (III) (in the formula, R31 is a monovalent to trivalent organic group and n31 is an integer 1-3) from a liquid phase component that is formed as a by-product in a method for producing a compound represented by general formula (I) (in the formula, R11 is a monovalent to trivalent organic group and n11 is an integer 1-3), wherein the collection method comprises steps (1)-(3) or steps (A) and (B), and step (4). Step (1): A step for reacting the liquid phase component with at least one kind of active hydrogen-containing compound in a reactor. Step (2): A step for returning a condensed liquid obtained by cooling gas phase components in the reactor to the reactor. Step (3): A step for discharging gas phase components that were not condensed in step (2) to the outside of the reactor. Step (A): A step for mixing the liquid phase component with water and a compound represented by general formula (III). Step (B): A step for reacting the liquid phase component with water inside the reactor. Step (4): A step for discharging, as a liquid phase component inside the reactor, the reaction solution containing the compound represented by general formula (III) to the outside of the reactor.
