Abstract
1334925 Analysis of organic compounds RHONE-POULENC SA 19 April 1971 [16 Feb 1970 4 Jan 1971] 21851/71 Heading B1X Elements, e.g. the halogens and sulphur, in an organic compound are quantitatively and automatically determined by combusting a known weight of the sample by direct or indirect heating in an atmosphere of oxygen in a vessel 1. The inorganic combustion products are swept away for analysis by an absorbent liquid, which may reduce the products, and which is caused to circulate in a closed path by a peristaltic or centrifugal pump 16. Upon completion of the analysis the circulation of the absorbent may be automatically stopped. The analysis may be volumetric, colorimetric or coulometric. As shown electrodes 18, 19 coulometrically determine the content of the element, and electrodes 20, 21 sense a predetermined concentration level, or pH, Fig. 3 (not shown). In a modification, Fig. 2 (not shown) the whole operation is carried out within the vessel which has a coaxial inner tube, around and through which the absorbent can be circulated. Chlorothiazide, brompbenzoic acid, dimethylsulphoxide and dihydroxydiphenylsulphone are mentioned as samples.
