A solution of ethyl iodide was prepared by breaking an ampulecontaining aknownweight of redistilled ethyl iodide under the surface of the. To enable estimates of the radiological hazard resulting from the inhalation of radio active methyl iodide to be made, measurements of its retention in a number of volunteer subjects were carried out, using iodine labelled methyl iodide. At normal breathing rates, the retention varied from 53 to 92%, depending princi pally upon the respiratory rate (breaths per minute); low rates corresponding to high Cited by: 5. insulin hypoglycemia on the circulation seemed desirable. METHOD OF STUDY All observations were made while the subjects were in the post-absorptive state, in bed, in a semi-recumbent position. The fasting blood sugar content wasdetermined according to the methodof Folin andWu(15). Thevital capacity of the lungs wasmeasured, andthe.

These data indicate that an exposure of L is sufficient to saturate the monolayer. We observe ethylene desorption at K during b-hydride elimination of ethyl groups on the Cu() surface. This is identical to the temperature reported in a previous study of ethyl iodide decomposition on the Cu() surface [11]. Ethyl iodide, clear liquid; boiling at C is used as an ethylating agent in organic synthesis for many application, for example, as solvents, intermediates for numerous chemicals, dyes, fumigants, sterilants, X-ray contrast media, antiseptics and pharmaceuticals. Ethyl iodide (C 2 H 5 I) decomposes at a certain temperature in the gas phase according to first-order kinetics as follows: C 2 H 5 I(g)? C 2 H 4 (g) + HI(g). The rate constant for this reaction is k = ×10?4 s? it to fill in the missing values in the following table.
