Procedure for the continuous preparation of aliphatic diisocyanates (cycle) |
| abstract |
Process for the continuous preparation of aliphatic (cyclo) diisocyanates by reaction of at least one aliphatic diamine (cycle) with urea and at least one alcohol to form aliphatic biscarbamates (cycle), and subsequent thermal dissociation of the aliphatic biscarbamates (cycle) to form aliphatic (cyclo) diisocyanates, characterized in that for the formation of aliphatic biscarbamates (unconditioned urea), urea is used, where the urea must not have been surface treated with inorganic substances and / or must not come from a molten mass of urea treated with formaldehyde or also paraformaldehyde and / or must not have been surface treated with formaldehyde or also paraformaldehyde. |
