Abstract
UNINFLUENCED by the economic depression, which has been felt in Central Europe as keenly as elsewhere, the various schools of chemical research in Czechoslovakia have continued their activities with undiminished energy, as is apparent from the papers published in vol. 6 of the Collection of Czechoslovak Chemical Communications. In inorganic chemistry, Dr. Skramovsky's 'stathmographic apparatus' has found further application in the study of complex inorganic salts such as the bismuth oxalates. The apparatus automatically records photographically the change in weight of a substance with, for example, increasing temperature. Striking dehydration curves have been obtained and results are found to vary according to well-defined circumstances. Thus copper sulphate crystals from aqueous solutions show quite different behaviour from those from alcoholic solutions. Further, inoculation with lower hydrated salt causes characteristic changes in the curves photographically recorded. The stathmographic method thus seems to promise a new field of investigation in inorganic chemistry. In physical chemistry, the Prague polaro-graphic school has published further work especially in connexion with the catalytic evolution of hydrogen at the dropping mercury cathode, which can be made use of in micro-analytical tests. Revenda's work in Prof. Heyrovsky's laboratory has extended the applicability of polarographic analysis to the anions. In organic chemistry, the Collection includes results of researches by Prof. Votocek and his collaborators on new conversions of sugars to furane compounds. New glucosyl-alkyl-amines are described, and the constitution of fuco-hexonic and rhodeo-hexonic acids has been worked out.
