Abstract: Essentially, a process is described for the preparation of the 1-triazolylethyl ether derivatives, defined in claim 1, of the general formula I (I) which consists in (a) reacting an oxirane of the formula II (II) at temperatures of -20 DEG to +100 DEG C., in the presence of an acid catalyst or an acid condensation agent, with an alcohol of the formula III R3-OH (III) to give a glycol monoether of the formula IV (IV) and (b) subsequently reacting the glycol monoether of the formula IV or one of its esters, in the presence of an acid-binding agent or condensation agent, at temperatures of 0 DEG to 150 DEG C., with a triazole of the formula V (V) the substituents R1, R2 ; amd R3 in the formula II to IV being as defined under formula I and M in formula V being hydrogen or a metal atom. The novel compounds within the scope of formula I and their use are also described.

Abstract: of the Dlsclosure (Dimethylamine , l)carboxylic and -carbamic acid esters and (dimethyL ? alkyl) ethers and ureas are compounds which are especially suitable for use as amine curing agents for polyepoxide compounds. They impart longer curing times to the curable mixtures and thus good processing properties, especially when the mixtures are used as adhesives. In sddition, the mechanical properties are often improved. Further, these compounds afford advantages when used as curing agents on account of their low volatility.

Abstract: Curable mixtures containing a) a polyepoxide compound having on average more than one epoxide group per molecule andb) a diamine which contains hydroxyl groups and has the general formula Ia or Ib (Ia) (Ib) in which R is an alkyl radical having 2 to 16 C atoms, an aralkylene radical having 7 to 12 C atoms, an arylene radical having 6 to 16 C atoms, a cycloaliphatic radical having 6 to 12 C atoms or a radical containing at least one N, O or S atom in chains or cyclic groups, and R1 is a hydrogen atom, a hydrogen atom or an alkyl group having 1 to 4 C atoms and in which, in formula Ia, the two OH groups are in the orthoposition or para-position relative to the methylene group, there being, in the mixtures, 0.5 to 1.5 equivalents of active hydrogen atoms, which are bonded to nitrogen and oxygen in the diamine containing hydroxyl groups, per 1 equivalent of epoxide groups.

Abstract: Process for the manufacture of polyglycidyl esters of aromatic, aliphatic, cycloaliphatic or heterocyclic polycarboxyclic acids, characterised in that polyalkyl esters, having 1 or 2 C-atoms in the alkyl group, of the corresponding polycarboxyclic acids are transesterified with at least stoichiometric amounts of monocarboxylic acid glycidyl esters, in the presence of a thallium compound as the catalyst, in a temperature range of 70 to 120.degree.C and the monocarboxylic acid alkyl ester formed during the transesterification is removed continuously from the reaction mixture.

Abstract: 1449380 3 - Amino - 4 - aminomethylpyrrolidines CIBA-GEIGY AG 11 July 1974 [25 July 1973] 30864/74 Heading C2C Novel compounds of Formula I wherein R 1 represents C 1-12 alkyl, a C 6 cycloaliphatic radical, benzyl, optionally substituted phenyl or 3-aminopropyl; R 2 represents hydrogen, C 1-12 alkyl or optionally substituted phenyl and R 3 represents hydrogen or C 1-6 alkyl; or R 2 and R 3 together represent a pentamethylene radical, are obtained by catalytic hydrogenation, at 20-150‹ C. in the presence of a solvent (e.g. ethanol), of the corresponding compound of Formula II R 1 to R 3 being defined as above with the addition that R 1 is #-cyanoethyl, separating the product from the catalyst and solvent, and, if desired, distilling the product. The hydrogenation is preferably carried out in the presence of ammonia as solvent and under superatmospheric pressure. Catalysts specified are Raney nickel, Raney cobalt, Pt, Pd, Rh and Ru. The starting materials of Formula II are prepared by the Thorpe-Ziegler cyclization of corresponding dinitriles in the presence of a basic catalyst and tertiary butanol. The pyrrolidines of Formula I are curing agents for epoxide resins.
