Saturated solution of potassium iodide

A solution of 0.46 g of the diazoketone in 100 ml of chloroform is shaken with 22 ml of 48 % hydriodic acid for 1.5 min. After the addition of 400 ml of chloroform, the organic layer is washed successively with a saturated solution of potassium iodide, with a solution of sodium thiosulfate and with water. After drying, evaporation of the solvent yields 0.44 g of a product which is chromatographed over 10 g of alumina (diam. of column 1.0 cm). Elution with benzene (400 ml) and benzene-ether (9 1) (200 ml) gives 0.32 g of 3jS,5) ,19-trihydroxypregnan-20-one 3,19-diacetate (yield 76%) mp 96-99°.

Identification Cautiously dissolve 250 mg of sample in 5 mL of glacial acetic acid, and add a few drops of a saturated solution of potassium iodide. Iodine is liberated. Add 20 mL of water and sufficient sodium thiosulfate TS to remove the iodine color. The resulting solution gives positive tests for Calcium, Appendix IIIA. 

Peroxide Value Accurately weigh about 10 g of sample, add 30 mL of a 3 2 mixture of glacial acetic acid chloroform, and mix. Add 1 mL of a saturated solution of potassium iodide, and mix for 1 min. Add 100 mL of water, begin titrating with 0.05 N sodium thiosulfate, adding starch TS as the endpoint is approached, and continue the titration until the blue starch color has just disappeared. Perform a blank determination (see General Provisions), and make any necessary correction. Calculate the peroxide value, as milliequiva-lents of peroxide per kilogram of sample, by the formula... 

Assay Transfer about 120 mg of sample, previously dried at 105° for 1 h and accurately weighed, into a 100-mL volumetric flask, dissolve in and dilute to volume with water. Transfer 50.0 mL of this solution into a 250-mL glass-stoppered iodine flask, add 50.0 mL of 0.1 N bromine and 20 mL of 2 A sulfuric acid, and stopper the flask. Place a few milliliters of a saturated solution of potassium iodide in the lip around the stopper, shake the flask well, and allow it to stand for 3 h. Place the flask in an ice bath for 5 min, then carefully remove the stopper, and allow the potassium iodide solution to be drawn into the flask. Add 2 g of potassium iodide dissolved in 10 mL of recently boiled water, shake the flask, and titrate the liberated iodine with 0.1 A sodium thiosulfate, using starch TS as the indicator. Each milliliter of 0.1 A bromine is equivalent to 2.311 mg of Mn(H2P02)2-... 

Add 10 mL of sample to 50 mL of a 3 2 (v/v) mixture of glacial acetic acid and chloroform. Add 1 mL of a saturated solution of potassium iodide to this solution, allow to stand for exactly 1 min with gentle shaking, and then introduce 100 mL of water and a few drops of starch TS. Titrate immediately with 0.1 N sodium thiosulfate. Each milliliter of 0.1 N sodium thiosulfate, multiplied by 5, equals the peroxide value, expressed in millimoles of peroxide per liter of the sample. 

Silver iodide is only slightly soluble in ammonia, but dissolves in sodium thiosulphate, concentrated hydriodic acid, and saturated solutions of potassium iodide.7 It forms a series of double salts with silver bromide,8 with mercuric iodide, and with the iodides of the alkali-metals.10 Double compounds of silver iodide and ammonia of the formulae AgI,8NH3 (6-92) AgI,l NH3 (7-25) AgI,NHs (8-56) AgI,2NHs (7-05) and AgI, NH3 (11-59) have also been prepared,11 the figures in parentheses indicating the calculated heats of formation in large calories.

The chemical dosimeter that is used most frequently is the thiocyanate dosimeter [119]. Other chemical dosimeters for pulse radiolysis are ferrocyanide [119], modified Fricke (Super-Fricke) [119], hydrated electron [120], 02-saturated solutions of potassium iodide [112], and N20-saturated solutions of methylviologen and formate [118]. The C(N02)4 (tetranitromethane, TNM) dosimeter is used in pulse radiolysis experiments with simultaneous optical and conductometric detection [121-124]. The composition and characteristics of the various chemical dosimeters used for pulse radiolysis with optical detection are listed in Table 8.

Adequate water intake generally is acceptable to maintain hydration and assist in the removal of airway sections. Beyond this, the regular use of mucolytics or expectorants for COPD patients has no proven benefit. This includes the use of saturated solutions of potassium iodide, ammonium chloride, acetylcysteine, and guaifenesin.

Iodide therapy (usually saturated solution of potassium iodide) is useful in reducing thyroid hormone release and in decreasing the vascularity of the gland prior to surgery. However, escape from the inhibitory effect of iodide often occurs in Graves disease, and the increased iodine substrate made available by the therapy may actually accentuate the disease.

Hydroperoxides content was determined spectrophotochemically. A sample of modified iPP was kept for 12 hours in vacuum for removing the physically adsorbed oxygen. Acetic acid and n-heptane were distilled and nitrogen was allowed to bubble through solutions. Then 3 ml of saturated solution of potassium iodide in isopropyl alcohol, 1 ml of glacial acetic acid and 1 ml of n-heptane were placed into a 10 ml Erlemayer flask.
