Thiophene was also hydrogenated to tetrahydrothiophene over rhenium heptasulfide (Re2S7) at 230-260°C246 or rhenium heptaselenide (Re2Se7) at 250°C and at pressures greater than 30 MPa H2 (eq. 12.129),247 without accompanying hydrogenolysis of the carbon-sulfur bond that occurred extensively over molybdenum sulfide.246... [Pg.562]

For the analysis of rhenium, the sample is fused with sodium peroxide and rhenium precipitated from hydrochloric acid solution as Re2S7 by hydrogen sulfide. The precipitate is dissolved in aqueous sodium peroxide and from dilute sulfuric acid solution, rhenium is determined by electrodeposition.8 Chlorine is determined gravimetrically by fusion of the sample with a sodium carbonate/ sodium nitrate mixture (95 5) in a platinum crucible and then precipitating as silver chloride. [Pg.118]
