Synthesis of silicates. (Agency of Industrial Sciences and Technology, Japan). Jpn. Kokai Tokkyo Koho JP 58185431 A2 29 Oct 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C01B033-20. APPLICATION: JP 82-67621 22 Apr 1982. DOCUMENT TYPE: Patent CA Section: 49 (Industrial Inorganic Chemicals) Homogeneous aq. solns. of silicic acid and Mg salts are mixed with alkali solns., the ppt. is filtered, washed with H2O, mixed with Li and Na cations, and optionally F-, heated at 100-300°, and dried to give hectorite-type silicates with a formula [Si8(Mg6-x-yLixNay)O20{(OH)4-zFz}](x+y)-.(x+y)M+, where 0 ￡ x < 2, 0 ￡ y < 2, 0 < (x+y) < 2, 0 ￡ z < 4, M+ = alkali metal ion or NH4+. Thus, 100 mL H2O was mixed with water glass 25.8 g and 16 N HNO3 7 mL, then mixed with 100 mL aq. soln. contg. 20.1 g MgSO4.7H2O to form a homogeneous soln., mixed with 20 mL of 28% NH4OH, the ppt. There are some commonly used reagents like 12173-47-6 in this article. is filtered, washed with H2O, mixed with 50 mL aq. soln. contg. 0.84 g LiOH.H2O and 6 mL 10% HF, refluxed for 24 h, and dried at 80° to obtain a hectorite-type product with methylene blue adsorption 98 mmol/100 g. .

Complexes of trimethylphosphine and dimethylphenylphosphine with cobalt(II) and nickel(II) on hectorite and on zeolites X and Y. Schoonheydt, Robert A.; Van Overloop, Rudi; Van Hove, Mathieu; Verlinden, Johan (Cent. Oppervlaktescheikd. Colloidale Scheikd., Kathol. Univ. Leuven, Louvain B-3030, Belg.). Clays Clay Miner., 32(1), 74-9 (English) 1984. CODEN: CLCMAB.Several substances with their cas registry numbers 74-86-2 and 12173-47-6 may be metioned in this study. ISSN: 0009-8604. DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) The gas-phase adsorption of Me3P on hectorite, exchanged with Co(II) and Ni(II), gives trigonal complexes of the type [M(Ol)3(PMe3)]2+ (M = Co, Ni; Ol = lattice O). Ten Dq values of PMe3 are 2.1 and 2.4 times larger than those of the structural oxygens or solvent mols. The same complexes form between Me2PhP and Ni(II) on hectorite and on synthetic zeolite Y. The Co(II) forms pseudotetrahedral complexes with Me2PhP. These surface-immobilized transition-metal complexes interact strongly with NO and C2H2 and to a lesser extent with CO and C2H4, giving new types of complexes. .
