| titleOfInvention | Multi-stage method for continuously preparing alicyclic diisocyanate |
| abstract | Multistep process for continuously preparing cycloaliphatic diisocyanates, comprises reacting a cycloaliphatic diamine with a carbonic acid derivative and an alcohol to produce a cycloaliphatic diurethane, separating the cycloaliphatic diurethane from low, middle and high boilers, and then thermally cleaving the cycloaliphatic diurethane to produce a cycloaliphatic diisocyanate, and continuously discharging a portion of the cleavage residue and reurethanizing the portion with an alcohol, and recycling the reurethanization product directly into the low-boiler separation. Multistep process for continuously preparing cycloaliphatic diisocyanates, comprises reacting a cycloaliphatic diamine with a carbonic acid derivative and an alcohol to produce a cycloaliphatic diurethane, separating the cycloaliphatic diurethane from low, middle and high boilers, and then thermally cleaving the cycloaliphatic diurethane to produce a cycloaliphatic diisocyanate, and continuously discharging a portion of the cleavage residue and reurethanizing the portion with an alcohol, and recycling the reurethanization product directly into the low-boiler separation; where the unconditioned urea and/or unconditioned urea produced from urea material are used equivalently. |
