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: A process for the decomposition of peroxides (I), is effected by contacting a mixt. contg. (I) with oxide catalysts (II) of manganese, iron, nickel, cobalt, cerium, copper, molybdenum, vanadium and/or tungsten. Pref. (I) is hydrogen peroxide and/or an organic peroxide (II) contains manganese, iron, cerium, copper, vanadium and/or tungsten. The active mass of (II) consists of 1-100 wt.% manganese oxide and 99-0 wt.% of the oxides of iron, cerium, copper, vanadium and/or tungsten and is supported, pref. on cordierite, Al203, Ti02, silica gel and/or Zr02. The reaction is carried out at 0-80 deg.C and 0.01-50 bar. USE/ADVANTAGE - The process is useful for the controlled decomposition of peroxides. The process stream is contaminated with heavy metal ions to a lesser extent than prior art processes.

Abstract: The invention relates to a process for the preparation of chlorofluorocarbon-free (CFC-free), elastomeric, semi-rigid or rigid mouldings containing urethane groups or urethane and urea 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 microporous activated charcoal and/or a microporous carbon molecular sieve, which preferably has a mean pore diameter with more than 40% in the range from 0.3 to 3 nm, a pore volume of from 0.20 to 1.4 ml/g and a BET surface area of from 500 to 2500 m /g or greater, and optionally further additives and g) auxiliaries, in a closed mould with compaction.

Abstract: Method for preparing titanium silicate crystals having a zeolite structure and being essentially free of alkali metals, by reacting hydrothermally an SiO2-containing mixture comprising water, a tetraalkylammonium compound, a titanium component and ammonia in the absence of a metal hydroxide or a metal salt at a molar ratio of ammonia/tetraalkylammonium of from 3:1 to 200:1.
