    Abstract: Photoreactor for photochemical syntheses, comprising, concentrically arranged from the inside to the outside, a lamp (4) with the electrical connections, an annular lamp cooler (5) made of glass with connections for a cooling medium flowing in and out and a reaction space (6) delimited by the outer casing of the lamp cooler and by the inner casing of the reactor (1) having a metal-coated interior wall, an apparatus (7) equipped with brushes or wipers (8) rotating in the reaction space, which apparatus is arranged so that on operation of the photoreactor, the outer casing of the lamp cooler is kept free from a light-absorbing deposit.

    Abstract: Preparation of diarylalkoxyphosphines Ar2P-O-R (I; Ar = optionally substituted phenyl; R = C1-C4-alkyl) from dihaloalkoxyphosphines of the formula Hal2P-O-R (II; Hal = Cl, Br) and arylmagnesium halides Ar-Mg-Hal (III) in the form of a solution in ether, by allowing II and III to react with each other in such a manner that II is not present in stoichiometric excess.

    Abstract: 2,2'-Dimorpholinodiethyl ether is produced by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen. The active hydrogenation catalyst, before reduction with hydrogen, contains 20-85 wt.% alumina, zirconium dioxide, titanium dioxide and/or silica, 1-70 wt.% copper oxide (CuO), less than 20 wt.% nickel oxide with respect to CuO and 0-50 wt.% other metal oxide(s). In the production of 2,2'-dimorpholinodiethyl ether (DMDEE) by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen and a hydrogenation catalyst, the active catalyst, before reduction with hydrogen, contains 20-85 wt.% aluminum oxide (Al2O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silica (SiO2), 1-70 wt.% copper oxide (expressed as CuO), 0-50 wt.% magnesium, chromium, zinc, barium and/or calcium oxide (expressed as MgO, Cr2O3, ZnO, BaO and CaO) and less than 20 wt.% nickel oxide (expressed as NiO) with respect to CuO.

    Abstract: Prepn. of a diamine (I) involves reacting an aminoalcohol (II) with ammonia or a prim. or sec. amine and hydrogen at 1-400 bars and 80-250 degrees C in presence of a catalyst (A) contg. the following oxygen-contg. metal cpds. in amts. (by wt.) 20-85% Zr cpd. (calculated as ZrO2), 1-30% Cu cpd. (calculated as CuO), 30-70% Ni cpd. (calculated as NiO), 0.1-5% cpd. of molybdenum (calculated as MoO3) and 0-10% cpds. of aluminium and/or manganese (calculated as Al2O3 or MnO2). Pref. (I) is NR R -Y-NR R , (II) is HO-Y-NR R and (III) is NHR R . R , R = 1-20C alkyl, 3-12C cycloalkyl, aryl, 7-20C aralkyl or 7-20C alkaryl; or R +R = (CH2)m-X-(CH2)n; R , R = H or as R , R ; X = O, CH2 or NR ; R = 1-20C alkyl, 3-12C cycloalkyl, aryl, 7-20C aralkyl or 7-20C alkaryl; Y = 2-12C alkylene chain, opt. substd. by 1-5 1-4C alkyl.
