    Abstract: PROBLEM TO BE SOLVED: To enable to industrially simply and profitably obtain the subject compound from a primary amine and a diol by using a specific copper- containing hydrogenation/dehydrogenation catalyst. SOLUTION: This method for producing an N-substituted cyclic amine of formula I comprises reacting (C) a compound of the formula: R -NH2 [R is an (alkoxy)alkyl, an aryl, etc.,] with (D) a compound of the formula: HO-A-OH A is an alkylene (substituted by a group of the formula: R (R is R ), a group of the formula: (CH2 )n -[O-(CH )m ]r , [(m), (n) are each 2-8; (r) is 1-3]} in the presence of a coppercontaining catalyst. The copper-containing catalyst is obtained by impregnating an inactive carrier (e.g. silicon dioxide, a silicate or zeolite) with (A) hydrogen and (B) the aqueous ammine complex solution of an easily pyrolytic copper compound (e.g. copper carbonate, copper oxalate or copper formate)(preferably an ammoniacal copper carbonate solution), drying the impregnated carrier, and subsequently calcining the dried product, and contains the copper in an amount of 5-50wt.% converted into CuO on the basis of the whole amount of the calcined catalyst.

    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).

    Abstract: The invention relates to a method for producing polytetrahydrofuran and polytetrahydrofuran copolymers, diesters or monoesters thereof by polymerising tetrahydrofuran in the presence of at least one telogen and/or comonomer on acid- activated montmorillonite catalysts, whereby the ratio of the montmorillonite structure to the sum of the muscovite and kaolin structure in the montmorillonite catalyst, which is determined from the intensities of the reflexes measured at 5.5 DEG 2È for montmorillonite, 9.0 DEG 2È for muscovite and 12,5 DEG 2È for kaolin is, after acid activation, at least 5:1.
