, p. 2781 - 2790 (2014)
In an effort to develop a green process for the production of elastomeric polyurethane-urea (PUaE) through a nonisocyanate route, a highly practical method was found using diphenyl carbonate (DPC) instead of diisocyanate as the carbonylation agent. The tr
MULTISTEP PROCESS FOR THE PREPARATION OF DIISOCYANATES

Page/Page column 17, (2019/04/26)
The present invention relates to a process for the preparation of organic diisocyanates by cleaving the corresponding diurethanes into the diisocyanate and a hydroxy compound and separating the diisocyanate from the hydroxy compound by distillation wherein the diisocyanate is obtained as the distillate.
Reaction method accompanied by production of gas component

Paragraph 18; 19, (2018/11/23)
The present invention relates to a reaction method comprising a step of supplying a liquid containing at least one raw material compound and a low-boiling compound having a standard boiling point lower than a standard boiling point of the raw material compound to a flow channel, a step of heating the liquid to produce a liquid reaction product and a gas component by a reaction of the raw material compound, and a step of separating a liquid phase containing the reaction product from a gas phase containing the gas component and the low-boiling compound.
