METHOD FOR PRODUCING CARBAMATE AND METHOD FOR PRODUCING ISOCYANATE

The present invention provides a method for producing a carbamate that includes a step (1) and a step (2) described below: (1) a step of producing a compound (A) having a urea linkage, using an organic primary amine having at least one primary amino group per molecule and at least one compound selected from among carbon dioxide and carbonic acid derivatives, at a temperature lower than the thermal dissociation temperature of the urea linkage; and(2) a step of reacting the compound (A) with a carbonate ester to produce a carbamate.

ISOCYANATE PRODUCTION METHOD

An isocyanate production method according to the present invention is a method in which an isocyanate is produced by subjecting a carbamate to thermal decomposition, and includes: a step of preparing a mixture liquid containing the carbamate, an inactive solvent and a polyisocyanate compound; a step of conducting a thermal decomposition reaction of the carbamate by continuously introducing the mixture liquid into a thermal decomposition reactor; a step of collecting a low-boiling decomposition product by continuously extracting the low-boiling decomposition product in a gaseous state from the reactor, the low-boiling decomposition product having a boiling point lower than the polyisocyanate compound; and a step of collecting a high-boiling component by continuously extracting, from the reactor, a liquid phase component which is not collected in a gaseous state at the step of collecting the low-boiling decomposition product.

METHOD FOR PRODUCING ISOCYANATE

PROBLEM TO BE SOLVED: To provide a method for producing isocyanate that suppresses a side reaction and continuously produces isocyanate. SOLUTION: The present invention provides a method for producing isocyanate by pyrolysis of carbamate, the method including: a pyrolysis step in which a liquid mixture containing carbamate and at least one compound (A) selected from a phenolic polymer having a repeating unit represented by general formula (4) and a phenol represented by general formula (5) is continuously introduced into a pyrolytic reactor for a pyrolytic reaction of carbamate; a low-boiling-point pyrolytic product recovery step in which a low-boiling-point pyrolytic product having a normal boiling point lower than that of the compound (A) is continuously extracted in a gas state from the pyrolytic reactor; and a high-boiling-point component recovery step in which a liquid phase component, which has not been recovered in a gas state in the low-boiling-point pyrolytic product recovery step, is continuously extracted as a high-boiling-point component from the pyrolytic reactor.
