| titleOfInvention | Multi-stage procedure for the continuous preparation of cycloaliphatic diisocyanates |
| abstract | Multi-stage process for the continuous preparation of cycloaliphatic diisocyanates, through a reaction of cycloaliphatic diamines with derivatives of carbonic acid and alcohols to give cycloaliphatic diurethanes and a subsequent thermal splitting of the diurethanes to give cycloaliphatic diisocyanates, characterized in that the formation of diurethanes is carried out in two stages, the diurethane released from the compounds that boil at low and intermediate temperatures is thermally split, releasing the desired diisocyanate, a part of the material from the splitting sump of the splitting equipment is continuously withdrawn, from which the components that They boil at high temperatures and the material removed, purified in this way, is reurethanized with an alcohol and recycled to the process. |
