Abstract: The invention relates to a process for the production of soft-elastic mouldings which contain urethane groups and are free from chlorofluorocarbons (CFCs), and have a cellular core and a compacted peripheral zone with an essentially pore-free, smooth surface, by reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and optionally c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents, e) catalysts, f) crystalline, microporous molecular sieves having a cavity diameter and cavity entrance aperture of less than 1.3 nm, comprising metal oxides or metal phosphates and optionally further additives, and g) assistants, in a closed mould with compaction, expediently by reaction injection moulding (RIM).

Abstract: A method is described for the conversion of diesters of general formula (II) by elimination of R6CO2H in the presence of phosphate or zeolite catalysts, into unsatd. monoesters (I), where in each case R1-R5 are H, straight or branched alkyl or alkenyl of C1-10, cycloalkyl or cycloalkenyl of C5-8, aryl, alkylaryl or arylalkyl; R6 is H or C1-6 alkyl. The value of n = 1-10. Zeolites may be aluminosilicates or ferrosilicates of the cyclopentasilicate type pref. arranged as a faujasite, i.e. in cuboctahedra, and may be doped with alkali, transistion or rare earth metals. Phosphates of B, Al, Zr, Cl, Fe, Sr may be used alone or in mixts..

Abstract: The invention relates to a process for the preparation of CFC-free, soft and elastic, semi-rigid or rigid mouldings containing urethane groups and having a cellular core and a compacted peripheral zone with an essentially pore-free, smooth surface, by reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms and optionally c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents, e) catalysts, f) at least one amorphous, microporous silica gel which preferably has a mean pore diameter with more than 40 % in range from 0.1 to 10 nm, a pore volume of from 0.15 to 1.8 ml/g and a BET surface area of from 200 to 900 m /g, and optionally further additives, and g) assistants, in a closed mould with compaction. t

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: Dien-1-ols of the general formula I (I) where the radicals R1 to R7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl or 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxylalkenyl tert-butyl ether of the formula II (II) in the presence of an acidic catalyst at elevated tempertures and essentially at the same time splitting off the tert-butyl protective group, as is 9-hydroxydodec-10-enyl 1-tert-butyl ether which is useful as an intermediate for synthesizing 8,10-dodecadienol.
