    Abstract: The present invention describes aminoalkyl-substituted organopolysiloxane thioureas consisting of units (I) wherein R1 stands for a group R5 stands for an alkylene grouping, R2 equals R1 or H, R3 equals R1 or H or a group (CH2)n-NR2 (III) in which n equals 1 to 6, R6 equals H or an alkyl group with C1 to C5, and R4 equals H or a group of Formula (III), wherein (I) contains at most two groups (II) and at most two groups (III) and the free valences of the oxygen atoms at the silicon atoms are saturated by silicon atoms of additional groups (II), optionally with the incorporation of cross-linking agents that contain Si, Ti, or Zr. The compounds can be statistical copolycondensates, block copolycondensates, or mixed copolycondensates with reference to the optionally present cross-linking agents. In addition, various production processes for the compounds are described. The compounds can be used, in particular, to remove dissolved metals from aqueous or organic phases.

    Abstract: The invention relates to monoclinic zirconium oxide having an SiO2 content of less than 1% by weight, which is characterised by dendrite-shaped particles having a mean grain size (d50 value) in the range from 0.5 mu m to 3.0 mu m and a specific surface area (BET) in the range from 3 to 15 m /g. The zirconium oxide is prepared by thermal cracking of zirconium silicate in a high-frequency or medium-frequency inductive fusion furnace with a sinter crust crucible, quenching of the melt by blowing air onto a melt jet and/or spraying the latter with water and leaching the thermally cracked zirconium silicate with concentrated alkali metal hydroxide solution at 100 to 200 DEG C. The zirconium oxides according to the invention is distinguished from prior zirconium oxide by its improved suitability for the production of zirconium silicate colouring materials of the host lattice and inclusion types - pigments of higher colour intensity are obtained.

    Abstract: New organopolysiloxanes contain units of formula (I), R1 is -CH2CH2- or CH3-CH-; x is 1-4, depending on M; M is H, a 1-4 valent metal ion or NH4. Free valencies of the O atom may be satd. by Si atoms of further gps. of formula (I) and/or by crosslinking bridging gps. of formula MO4/2, R'MO3/2, (R')2MO2/2, AlO3/2 or R'AlO2/2 and/or by unsulphonated phenylene units of formula (II), M is Si, Ti or Zr; R' is Me or Et. Ratio of the sum of Si in (I) and (II): Si, Ti, Zr and Al in the bridging gps. is 1:0-15. When Mx+ is H+, the organopolysiloxane pref. has a H+ capacity of 0.1-3.16 meq/g. of polymer. Organopolysiloxane may be tempered for 1 hr. to 5 days at 100-350 deg.C in air or under a protective gas, at normal or excess pressure, or in vacuo.
