Method for producing carbodiimide |
| abstract |
A process for the production of a carbodiimide, comprising the steps of: n(1) reacting an amine represented by the following formula (A) with carbon disulfide in the presence of a catalyst at a reaction temperature of 50 to 150°C to obtain a thiourea represented by the following formula (B):n n(In the above formula (A), R is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms.)n n(In the above formula (B), R is as defined in the above formula (A).; n(2) desulfurizing the obtained thiourea with a hypochlorite in the presence of a basic compound to obtain a carbodiimide represented by the following formula (C):n n(In the above formula (C), R is as defined in the above formula (A).); and n(3) purifying the obtained carbodiimide. |
