    Abstract: Method for the undercoating or impregnation of natural or synthetic mineral building materials with aq. suspensions or solns. that contain 0.1-70 (10-30) wt.% at least one silicon-contg. ion exchange material of formula (I) or an oligomer thereof, w.r.t. soln. or suspension. The treatment method is a single- or multi-stage process and is opt. combined with a treatment process with organic or aq. solns. or emulsions contg. hydrolysable sil(ox)anes. Ä(YO)3Si(CH2)xÜnEX (I) x = 1-12; n = 1-3, depending on E; Y = H, Na, K, Mg, Ca or Ba; E = cation or anion exchanging gp.; and X = H or alkali(ne earth) metal ion, or OH or an anion.

    Abstract: The formed sulphonate and SH gp.-contg. organo-polysiloxanes (OFP) contain units of formula (I) and (III): ÄO3/2SiR1SO3ÜxMx+ (I) O3/2SiR2SH (III) where R1 = 1-12 C alkylene, 5-8 C cycloalkylene or a gp. of formula -(CH2)n-Cy-(CH2)m- or -(CH2)n-Ph-(CH2)m- (II); where n and m = 0-6; Cy = cyclohexylene; Ph = phenylene; M = H, NH4 or a metal ion with a valency of 1-4; R2 = R1; the free valencies of the O atoms attached to Si are taken up by the Si atoms in other gps. (I) and/or (II) and/or by the metal atom-oxygen gps. in crosslinking bridging gps. of formula SiO4/2 (IV) and opt. R''SiO3/2, R'SiO3/2, AlO3/2, R'AlO2/2, TiO4/2, R'TiO3/2 (V), in which R' = Me or Et; R" = Ph or 2-12 C alkyl. The ratio of gps. (I):(III) is 10:1-1:10, the ratio of gps. (I):(IV) is 1:3-1:20 and the ratio of gps. (IV):(V) is 1:0-1:0.5. Also claimed is a process for the prodn. of OFP.

    Abstract: The invention relates to shaped organosiloxanamine copolycondensates which contain Pd, Pt, Ru and/or Rh and optionally also promoters and/or moderators. The shaped copolycondensate, which is used as a support for metal, comprises units and units and/or Y-R units. R to R are a group in which R is an N-, X- or Y- bonded radical (for example an alkylene radical), and R is R -SiO3/2, H, CH3, C2H5 or C3H7. X is a divalent radical, such as -S-, -S2- to -S4-, -HN-CS-NH-, and Y is a monovalent radical, such as -CN-, -SCN, -SH, -S-CH3, -NH2, or -NH-(CH2)2-NH2. The support substance may have been crosslinked by means of Si-, Ti-, Zr- or Al-containing crosslinking agents. The metal-containing product has a spherical shape and is defined by means of the parameters sphere diameter, specific surface area, pore volume and bulk density. The invention furthermore relates to a preparation process, which can be carried out in a number of variants, and for the use of the metal-containing product as a catalyst for hydrogenation and oxidation reactions.

    Abstract: Preparation of primary and/or secondary amines (I) from oxo compounds (II), which may contain other reducible groups, especially for preparation of isophorone diamine (IA) from isophorone nitrile (IIB), involves (a) converting (II) to an imine by reaction with ammonia for preparing primary amines or with a lower monoalkylamine for preparing secondary amines in the presence of a catalyst for imine formation and optionally an organic solvent; and (b) hydrogenating the reaction products with hydrogen (H2) at 20-250 degrees C and 0.5-25 MPa in the presence of a hydrogenation catalyst. The novelty is that the catalyst for imine formation is an organopolysiloxane (III) containing sulphonate groups, which is resistant to dissolution in the reaction medium.
