“…1.2-Dibromo-ethane can be analyzed by several methods using monoethanolamine and Volhard titration (8), amperometric titration (7), or iodometric titration (5, 6), and the residual fumigant, by extraction and iodometric titration (4). Since low dosages of the fumigant are effective, an accurate, simple, and rapid method for the determination of small amounts was needed.…”

were quite pronounced. The first dilution almost eliminated decomposition and produced a corrected CS2 reading of 244 units, approximately the reading which would be expected from 25.3 mg. of CS2 per liter when inhibition is complete (Figure 4). The first dilution of "Fire inhibited" 80:20, which contained 1% re-pentane, completely eliminated decomposition and produced a corrected CS2 reading of 245 units. The joint inhibitory effects of CCh and pentane apparently raised the lower limit of the critical CS2 concentration range above that for CS2 in 80:20 without pentane.

“…Unsuccessful attempts were made to replace formaldehyde by a reducing agent such that neither the excess of reagent nor its oxidation product would introduce later complication. The substances tried were acetaldehyde, chloral hydrate, glucose, glycerol (22), and ethanolamine (19,23). As no satisfactory agent was found, it became obvious that the metal must be isolated by filtration.…”
