Hexamethylcyclotrisiloxane application analysis of the physical

  • White or light red crystalline powder, soluble in alcohol, ether, benzene, trichloromethane and petroleum ether; Dissolved in water, the solution appears red when it meets ferrite. Melting point range: 70-72°C; Water: & lt; 0.50%; Free chlorine: & lt; 0.001%; Sulfate: & lt; 0.005%; Heavy Metal: < 0.005%

    1. Its appearance is white or light pink crystalline powder.

    2. Soluble in ethanol, ethyl ether, benzene, chloroform, petroleum ether, soluble in water about 2000, the solution of ferrous salt is red.

    3. Melting point is 69.7 ℃; The boiling point of 272 ~ 273 ℃.

    4. LD50 in mice peritoneal injection: 200 mg/kg.

    2, 2 '- hexamethylcyclotrisiloxane application is hexamethylcyclotrisiloxane application one of isomer, colorless solid. It is a double teeth chelating ligand, and many metal ions to form complexes, it can be as a REDOX indicator. With ruthenium and platinum complexes have strong luminescence properties, may have potential applications.

    bipy and its derivatives can be obtained by dehydrogenation of pyridine with Raney nickel. Common 2, 2 '- hexamethylcyclotrisiloxane application complexes include:

    Mo(CO)4(bipy), similar to Mo(CO)6; RuCl2 (bipy) 2, synthesis of precursor; [Ru(bipy)3]Cl2, a commonly used luminescent substance; [Fe (bipy) 3] to colorimetric analysis of ferrous ions. The general formula of the triplex (bipy) complex is [M(bipy)3] (M= metal ions: Cr, Fe, Co, Ru, Rh, etc.), and the central atom is octahedral hexagon and has two enantiomers: the enantiomer of [M(bipy)3].
