    摘要： Cycloaliphatic diisocyanates can be prepared continuously and phosgene-free by reacting at least one cycloaliphatic diamine with at least one carbonic acid derivative and at least one alcohol to give a cycloaliphatic diurethane; freeing the cycloaliphatic diurethane of a low boiler, a medium boiler and mixtures thereof; thermally cleaving the cycloaliphatic diurethane in a cleavage apparatus to give a cycloaliphatic diisocyanate and a cleavage residue; continuously discharging a portion of the cleavage residue from the cleavage apparatus; removing the high boiler components from the discharge to obtain a purified discharge; reurethanizing the purified discharge with alcohol to obtain a reurethanized discharge; and recycling the reurethanized discharge into the process.

    摘要： Low-odor, storage-stable monomer-containing polyisocyanurate is prepared from isophorone diisocyanate by conducting a partial trimerization for 3 minutes to 3 hours in the presence of 0.05-2% by weight of a catalyst, based on the weight of the diisocyanate, the catalyst having the formula [R—NX3]m⊕mY⊖ wherein Y⊖ is a carboxylic acid anion of 4-8 carbons, R is a &bgr;-hydroxyalkyl group of 2-6 carbons, X is an alkylene group of 2-3 carbons and m is a number from 1.0 to 2.0. The three radicals X form a ring with the quaternary nitrogen by way of a common nitrogen atom, which may be partly &bgr;-hydroxyalkylated, said ring optionally having an OH group positioned &agr;, &bgr; or &ggr; to the nitrogen. The reaction proceeds at a temperature of 0-160° C.
