Abstract: Opt. substd. 1,4-diazabicyclo(2,2,2)-octanes of formula (I) in which R1 and R2 = H, 1-4C alkyl or 1-4 C alkylene, are prepd. by conversion of heterocyclic amines of formula (II) in which R1 and R2 are as above, R3 = H, hydroxy or aminoethyl and X = hydroxyl, amino, hydroxy or aminoethyl gp., in the presence of L-zeolites, phosphates with a zeolite structure, or Zr phosphates as catalyst. Zeolites are used as catalyst in conversion of heterocyclic amines (II) into 1,4-diazabicyclo(2,2,2)-octanes.

Abstract: 4-Hydroxyphenylacetonitrile (I) is produced by the gas-phase reaction of 4-methoxyphenylacetonitrile (II) at 280-4500 deg.C and 0.01-50 bar on zeolites or structurally-related Al-contg. phosphates (III) in the presence of water vapour. Pref. (III) is a pentasil, alumino, gallium- or borosilicate zeolite, a pentasil zeolite contg. at least 2 of the above elements as tetrahedral cations in the pentasil lattice, a zeolite of the faujasite or mordenite type, or a crystalline Al-contg. phosphate with a mol. sieve structure, obtd. by a hydrothermal process. USE/ADVANTAGE - Useful for the prodn. of 2-(4-hydroxyphenyl)-ethylamine, 4-hydroxyphenylacetic acid and 4-hydroxyphenylacetamide (claimed). Provides an improved process for heterogeneous catalytic hydrolysis of a phenol ether, without the disadvantages of prior-art homogeneous processes (e.g., laborious sepn. of catalyst, reduced yield due to further reaction of the prod. with the catalyst).

Abstract: Hydroxybenzaldehydes of the formula (I) are prepared from a benzaldehyde of the formula (II) or its acetal, in which R1 in the R1O-phenyl ether group is an alkyl, cycloalkyl, alkylcycloalkyl or alkylaryl radical, R2 is H or OH or is identical to R1 and one or more R1O-phenyl ether groups are ortho, meta or para to the aldehyde function, by a process in which a benzaldehyde of the formula (II) or its acetal, in which R1 and R2 have the abovementioned meanings and one or more R1O-phenyl ether groups occupy the abovementioned position with respect to the aldehyde function, is converted into a hydroxybenzaldehyde of the formula (I) in the presence of water over a zeolite as a heterogeneous catalyst. The catalysts used are, in particular, zeolites of the pentasil type.

Abstract: Cyclopentanone is prepared from adipic esters by reacting adipic esters of the formula R1OOC-(CH2)4-COOR2 where R1 and R2 are alkyl of 1 to 12 carbon atoms, cycloalkyl of 5 or 6 carbon atoms, aralkyl or aryl and R2 can additionally be hydrogen, in the gas or liquid phase at from 150 DEG C. to 450 DEG C. in the presence of zeolitic catalysts and/or phosphate catalysts, preferably zeolites of the pentasil type.

Abstract: Process for the preparation of 2-(3-aminopropyl)cycloalkylamines of the general formula I in which the index n is an integer from 1 to 4, from 2-(2-cyanoethyl)cycloalkanones of the general formula II in which the index n has the abovementioned meaning, by carrying out the following steps in two reaction spaces spatially separated from one another: a) reacting the 2-(2-cyanoethyl)cycloalkanones of the formula II in a first reaction space with excess ammonia over acidic heterogeneous catalysts at temperatures of 20 to 150 DEG C and pressures of 15 to 500 bar and b) hydrogenating the reaction products in a second reaction space with hydrogen in the presence of excess ammonia over cobalt-, nickel-, ruthenium- and/or other noble metal-containing catalysts which may contain basic components or are present on neutral or basic supports at temperatures of 60 to 150 DEG C and pressures of 100 to 500 bar, and also the novel compound 2-(3-aminopropyl)cyclopentylamine.
