Method for producing carbamate and method for producing isocyanate |
| abstract |
The present invention provides a method for producing a carbamate that includes a step (1) and a step (2) described below:n (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. |
