Summary

A spectrophotometric study has been made of the solvent extraction of molybdophosphoric acid and its blue reduction product with propylene carbonate from acidic solutions. Molybdophosphoric acid forms an adduct with propylene carbonate which is readily extracted with chloroform. The molar absorptivity of the molybdophosphoric acid in the propylene carbonate-chloroform phase is 22300 1 mole−1 cm−1 at 308 nm. Although experimental conditions for the extraction of the heteroply blue must be more carefully controlled, this extract exhibits a molar absorptivity of 28500 1 mole−1 cm−1 at 790 nm.

Zusammenfassung

Eine spektrophotometrische Untersuchung der Extrahierbarkeit der Molybdänphosphorsäure und ihres blauen Reduktionsproduktes mit Propylencarbonat aus saurer Lösung wurde durchgeführt. Molybdänphosphorsäure bildet mit Propylencarbonat ein Addukt, das mit Chloroform gut extrahierbar ist. Ihre molare Absorption in der Propylencarbonat-Chloroform-Phase beträgt 223001·mol−1 · cm−1 bei 308 nm. Die experimentellen Bedingung für die Extraktion der blauen Heteropolysäuren müssen zwar noch genauer geprüft werden, die molare Extinktion kann jedoch mit 285001·mol−1·cm−1 bei 790 nm angegeben werden.
