Abstract

Es wird eine Methode zur Bestimmung von Halogengemischen in organischen Verbindungen beschrieben Diese werden im Sauerstoffstrom nach einer speziellen Methode verbrannt Die Verbrennungsgase werden in einer gesättigten wäßrigen Hydrogensulfitlösung absorbiert und die Summe der Halogene wird nach dem Entfernen des überschüssigen SO2 volumetrisch mit einer 001n QuecksilberPerchloratlösung in hochprozentigem Äthanol bestimmt Für die Einzelbestimmung von Brom bzw Jod in Gegenwart anderer Halogene dagegen benutzt man alkalische Absorptionslösungen und die übliche TitrationsmthodeA method for determining mixtures of halogens in organic compounds is described The samples are burned in a stream of oxygen by a special procedure The combustion gases are absorbed in a saturated aqueous solution of hydrogen sulfite and after the excess of sulfurous acid is removed the sum of the halogens is determined titrimetrically by means of 001N perchlorate solution ha high percentage ethanol The individual determination of bromine or iodine in the presence of other halogens is accomplished by absorption in alkaline surroundings followed by the customary titration methodOn décrit une méthode de dosage de mélanges dhalogènes dans les composés organiques On réalise la combustion de ceuxci dans un courant doxygène suivant une méthode spéciale Les gaz de combustion sont absorbés par une solution aqueuse saturée dhydrogénosulfite et lon dose la somme des halogènes par volumétrie par une solution de perchlorate 001N dans léthanol absolu après avoir chassé SO2 en excès Pour le dosage individuel du brome ou de liode en présence dautres halogènes on utilise alors des solutions dabsorption alcalines et la méthode habituelle de titrage
