concentration of 2 mg./litre, reduction is complete in 5 min. and the reduction time is not materially reduced by higher molybdenum concentrations. The effect of the residual iron colour on the calibration graph is shown in Fig. and it will be observed that the effect is more pronounced in the presence of phosphoric acid.

## Abstract The method of fluorination using antimony pentachloride and anhydrous hydrogen fluoride^1^ has, by a simple modification, been extended to allow the almost quantitative conversion of the ‐C,Cl~3~ radical to ‐CF~3~, in chloroform, carbon tetrachloride, as‐tetrachloroethane, and methyl ch
