Abstract: Organic diurethanes and/or polyurethanes are prepared by reacting organic diamines and/or polyamines (a) with urea and/or alkyl cabamates (b) and alcohols (c) in the presence of soluble zirconium compounds, preferably zirconium alkoxides, zirconium acetate or zirconium acetylacetonate, as catalyst (d). They can be used for preparing diisocyanates and/or polyisocyanates by thermal dissociation.

Abstract: The invention relates to 2,2-dialkylpentane 1,5-diisocyanates, 2,2-dialkylpentane-1,5-diurethanes and 2,2-dialkylpentane-1,5-dicarbamoyl chlorides of the formula: where: R1 and R2 are identical or different linear C1- to C22-alkyl, branched C3- to C12-alkyl, branched C2- to C12-alkenyl or branched C4- to C12-alkenyl, or R1 and R2 together are alkylene having from 4 to 7 carbon atoms, which is unsubstituted or substituted by from 1 to 5 C1- to C4alkyl groups, and X is NCO, NH-CO2R3, NHC2R4 or NHCOCl, where R3 and R4 are identical or different and are linear C1- to C20-alkyl, branched C3- to C20-alkyl or C5- to C12-cycloalkyl. The 2,2-dialkylpentane-1,5-diurethanes of the above formula are useful as pesticides. Like the 2,2-dialkylpentane-1,5-dicarbamoyl chlorides also defined above, they are also useful for the preparation of the above 2,2-dialkylpentane 1,5-diisocyanates, which are themselves useful for the preparation of compact or cellular plastics by polyisocyanate polyaddition.

Abstract: The prodn. of isocyanurate gp.-contg. polyisocyanates (A) comprises partial trimerisation of (cyclo)aliphatic di-isocyanates (B) in the presence of tetra-alkylammonium alkyl carbonates of formula (I) and/or quat. ammonio-alkyl carbonate betaines of formula (II) as catalyst(s), followed by deactivation of the catalyst on reaching the required deg. of trimerisation. In formulae, R , R , R = 1-20 C alkyl, 5-6C cycloalkyl, 7-10C aralkyl or Ph; or R + R can form a 5- or 6-membered cycloalkyl gp., or R + R + N can form a 5- or 6-membered ring with another N or O as bridging gp. or R + R + R + N can form a multi-membered ring with one or more extra N and/or O bridges; R = 1-4C alkyl; R = 2-20 C alkylene, 5-6C cycloalkylene, 7-10C aralkylene or phenylene; or R + R = alkylene gp. which forms a 5- to 7-membered ring with a N bridge. Pref. trimerisation catalysts are carbonates of formula (III), (IV), or (V), or betaine carbonates of formula (V), (VII) or (VIII). Trimerisation is carried out at 30-150 degrees C and the catalyst is deactivated with dibutyl phosphate (DBP); unreacted monomeric di-isocyanate is then removed. Pref. di-isocyanates are (cyclo)aliphatic di-isocyanates obtd. by a phosgene-free process, esp. by thermal cleavage of (cyclo)aliphatic dicarbamate esters; esp. pref. di-isocyanates obtd. by this method are 1,6-hexamethylenedi-isocyanate (HDI), 2-butyl-2-ethyl-pentamethylene-1,5-di-isocyanate and 1-isocyanato-3-isocyanatomethyl-3,5,5-trimethylcyclohexane (IPDI).
