Abstract
The electrolytic separation of Ta and Nb from cryolitic solutions of their respective pentoxides gives, under specified conditions, a yield of 90% of the initial Nb with a purity better than 98%.

## Abstract Two radiochemical methods for the quantitative determination of tantalum and niobium, with the aid of ^182^Ta and ^95^Nb, are described. If only one of these radio‐isotopes is present, it can be determined by counting the gamma radiation emitted in a well‐cristal scintillator. The simul
## Abstract The synthesis of 1‐fluoro‐4,4‐di‐hydroxymethyl‐pentane (I) and its dicarbamate (II) is described. (I) is obtained by classical alkylation of methylmalonic ester with 1‐ bromo‐3‐fluoro‐propane and subsequent reduction with LiAlH~4~, of the fluorinated diester obtained. Treated with phosg
## Abstract Some new fluorinated hydroxy‐acids and hydroxy‐ethers as well as their phosphorylated derivatives are described.
