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 preparing IPDI (isophorone diisocyanate)

The invention discloses a method for preparing IPDI (isophorone diisocyanate). The method comprises the following steps: (1) isophorone and hydrogen cyanide are subjected to a reaction in the presenceof a catalyst to obtain isophorone nitrile; (2) isophorone nitrile obtained in step (1), ammonia and hydrogen are subjected to a reaction in the presence of a catalyst to obtain isophorone diamine; (3) isophorone diamine is subjected to a phosgenation reaction to obtain IPDI, wherein the content of impurities containing secondary amine groups in isophorone diamine subjected to the phosgenation reaction in step (3) is smaller than or equal to 0.5wt%, preferably smaller than or equal to 0.3wt%, and more preferably smaller than or equal to 0.1wt%. By means of the method, content of hydrolyzed chlorine in the IPDI product can be effectively reduced, the yellowing resistance of the product is effectively improved, and the harm that downstream products are unqualified due to existence of hydrolyzed chlorine in the product is reduced.
