Oxidation of Fluorine-Containing Alcohol with Chlorine

Catalytic reactions of chlorite with a polypyridylruthenium(II) complex: disproportionation, chlorine dioxide formation and alcohol oxidation.

cis-[Ru(2,9-Me(2)phen)(2)(OH(2))(2)](2+) reacts readily with chlorite at room temperature at pH 4.9 and 6.8. The ruthenium(II) complex can catalyze the disproportionation of chlorite to chlorate and chloride, the oxidation of chlorite to chlorine dioxide, as well as the oxidation of alcohols by chlorite.

A NEW GENERATION OF OXYNITRIDE GLASSES CONTAINING FLUORINE

Oxynitride glasses are found as grain boundary phases in silicon nitride ceramics. They are effectively alumino-silicate glasses in which nitrogen substitutes for oxygen in the glass network, and this causes increases in glass transition and softening temperatures, viscosities (by two to three orders of magnitude), elastic moduli and microhardness. Calcium silicate-based glasses containing fluo...

Anilines Oxidation with Chlorine Dioxide in Wastewater

Oxidative behaviors of three toxic pollutants including aniline, p-toludine and p-chloroaniline with ClO2 in water were studied with HPLC. The removal rates of anilines were used as criteria in this experiment. Effects of the ClO 2 concentration, pH and reaction time on the removal rate of anilines were discussed. The results show that for 1mmol ·L-1 aniline, p-toludine and p-chloroaniline, the...

Fluorine-containing Elastomers Introduction

Introduction of fluorine and fluorine-containing functional groups.

Over the past decade, the most significant, conceptual advances in the field of fluorination were enabled most prominently by organo- and transition-metal catalysis. The most challenging transformation remains the formation of the parent C-F bond, primarily as a consequence of the high hydration energy of fluoride, strong metal-fluorine bonds, and highly polarized bonds to fluorine. Most fluori...
