- An isocyanate compound containing 1,3-XDI ( m -XDI) was obtained in the same manner as in Example 1, except that the temperature of the bottom of the distillation column 220 was operated at 155 ° C. .
- Example 2 In the same manner as in Example 1, except that in the degassing step, the temperature of the bottom of the distillation column 220 was 140° C. and the pressure of the top of the distillation column 220 was operated at 400 torr. An isocyanate compound containing 1,3-XDI ( m -XDI) was obtained. In the manufacturing method, there was an outflow of phosgene in the degassing step.
- Example 2 In the same manner as in Example 1, except that in the desolvation step, the temperature of the bottom of the distillation column 330 was 160° C. and the pressure of the top of the distillation column 330 was operated at 50 torr. An isocyanate compound containing 1,3-XDI ( m -XDI) was obtained. In the manufacturing method, it was found that the residual amount of low boiling water was relatively high in the step of removing boiling water.
