2 . 1 . Lassaigne bromine and iodine are to be detected, filtration is not decomposition. Y, necessary. , with the turbid solution, and dry. If the compound to be examined contained (b) nitrogen or sulphur, treat the disc with a drop of (1 + 1) nitric acid and heat over the flame of ether a microburner to the appearance of vapours. In (c) this way cyanide and thiocyanate ions, formed from compounds containing nitrogen or sulphur, will be decomposed and expelled. In the presence of halide ions, add a droplet of 5 % (ö) silver nitrate solution to the filter paper disc, to give silver halide precipitates which will be readily visible on the black background.
1,3-Difluoro propane reacts with sodium ethylate, but far less vigorously than 1,3-dichloro propane. However, in w'c-difluoro derivatives, the C — F b o n d is very unstable. Thus, for example, 1,2-difluoro propane can easily lose hydrogen fluoride in the presence of water, yielding ethylene glycol. Alicyclic polyfluoro compounds lose fluorine from adjacent carbon atoms under the influence of strong bases. The presence of a chlorine a t o m at the carbon adjacent to the fluorine also loosens the C—F b o n d ; bromine atoms do not have such an effect.
5; the screen is coated inlet; 3, platinum screen; 4, gas inlet; with an alkali metal hydroxide. The 5, hydrogen inlet; 6, air inlet 64 ANALYTICAL CHEMISTRY OF ORGANIC HALOGEN COMPOUNDS collector electrode protrudes into the flame a n d another flame ionization detector is installed above this device. When gases or pyrolysis products containing halogens get into the flame of the lower detector, the halide ions formed considerably increase the rate of evaporation of alkali metal ions from the screen coating which is detected by the upper detector.
