“…The experimental values for the viscosity of iodine vapor at 8 kPa (60 mm Hg) are determined over the temperature range 380-800 C, in reasonable agreement with those calculated by the Sutherland equation (19,20). The viscosity of liquid iodine at a temperature just above the melting point is 1.98 mPa(¼ cP) as compared to the 2.35 mPa (¼ cP) calculated by Andrade and Lindemann's equation.…”

Iodine is a nonmetallic element belonging to the halogen family in Group 17 VII of the Periodic Table. Iodine is one of the scarcest of the nonmetallic elements in the total composition of the earth. Wherever iodine occurs, its quantities are generally exceedingly small and very sophisticated chemical methods are required to detect iodine. As found in nature, iodine has only one stable isotope. Several radioactive isotopes have been prepared and have found use as radiopharmaceuticals or tracers for medical imaging. Iodine is produced as a nitrate ore byproduct or from brines or seaweeds. Iodine is much safer to handle at ordinary temperatures than the other halogens because it is a solid at ambient temperatures and pressures. Current demand for iodine is for use in biocides, iodine salts, LCDs, synthetic fiber treatments, and x‐ray contrast media. Important inorganic and organic iodides and iodates are discussed

“…Measurements of the density of solid iodine have been extended to low temperatures, eg, d at À195 C ¼ 5:15 g=mL; the atomic volume at À273 C obtained by extrapolation is 24.5 mL (17,18). The experimental values for the viscosity of iodine vapor at 8 kPa (60 mm Hg), are determined over the temperature range 380-8008C, in reasonable agreement with those calculated by the Sutherland equation (19,20). The viscosity of liquid iodine at a temperature just above the melting point is 1.98 mPa(¼cP) as compared to the 2.35 mPa (¼cP) calculated by Andrade and Lindemann's equation.…”

“…14 IODINE AND IODINE COMPOUNDS 15isoxanthrone) is an orthochromatic sensitizer for photographic emulsions and also a certified food colorant (see COLORANTS FOR FOODS, DRUGS, COSMETICS, AND MEDICAL DEVICES). Iodine consumption in erythrosine may be estimated to be about 750 tons/yr(20). Dyes are not expected to show any major growth in the future.…”

Iodine is used in a wide variety of fields, among which are included industrial, pharmaceutical, nutritional, agricultural, electrical, and metallurgical. Iodine is produced as a nitrate ore by‐product or from brines or seaweed. As found in nature it has only one stable isotope. Several radioactive isotopes have been prepared and have found use as radiopharmaceuticals or radioactive tracers for medical imaging. Iodine is the only halogen that is solid at ambient temperatures and pressures. Having the highest atomic weight of the common halogens, iodine begins to exhibit metallic properties. Besides exhibiting properties of luster and opacity, it is classed as a semiconductor of electricity. It is an essential human nutrient. Commercially available inorganic and organic compounds are described.

“…1 For the only case in which comparison with experiment is possible-that of methane 9 -the experimental value of RT is 0.29±0.03; the value obtained by Brown from (2) is 0.46, and the corrected value (5) is 0.39. The difference between (5) and (2) is not sufficient to invalidate any of the qualitative arguments presented by Brown.…”
