Except for problems with delayed or inadequate fixation as noted above, problems with the trichrome stain are usually related to reagents other than the stain. If crystalline material is apparent after the specimen is stained, the crystals are probably mercuric chloride in the fixative which was not adequately removed because the iodine in the alcohol-iodine solution was too weak or because the slide was in this solution too short a time. If crystals are present after treatment with proper-strength iodine-alcohol, they are present in the specimen, which is thus unsatisfactory, and another specimen should be requested. 

Hypohalites IRO-Hal) are similar to nitrates (see p. 155 in their photochemical behaviour. Ultraviolet irradiation gives an (n,Ji > excited state that cleaves to form an alkoxy radical and a halogen atom. The radical may undergo alpha-cleavage before recombination with the halogen atom occurs, and this accounts for the formation of 5-iodopentanal (5.69) from the hypoiodite of cydopentanol such hypoiodites are generated in situ from the alcohol. Iodine and merturyfll oxide. In open-chain systems the alkoxy radical can... 

A complication of the use of alcoholic iodine solution has been described in three women undergoing cesarean section, who developed painful, superficial, inflammatory reactions on their buttocks after skin preparation for surgery with 10% iodine in alcohol (59). These lesions were believed to have been caused by pooling of the solution underneath the patients, topical skin damage being exacerbated by heat and occlusive drapes.

The poly(vinyl alcohol)-iodine charge transfer complexes have been the subject of many investigations " Water-soluble iodine complexes with ix)ly(l-vinyl-pyrrolidone) are commercially available as disinfecting agents PoIy(N-vinyl car-bazole) polyamides and poly(ethylene oxide) are also found to form molecular addition complexes with iodine and iodine compounds. An account of the different types of molecular complexes formed with various polymers has been published ... 

Mercury di-n-octyl. —Octyl iodide is treated with dilute sodium amalgam in the presence of ethyl acetate, and after completion of the reaction the mass is extracted with ether. Evaporation of the solvent gives an oily liquid of density 1 342 at 17° C., which decomposes at about 200° C. into di-octyl and metallic mercury. When the starting materials are pure it is stated that no by-products occur. Mercury di-n-octyl is insoluble in water, but readily soluble in alcohol, ether, or benzene. Treatment with alcoholic iodine or mercuric chloride yields the corresponding di-n-oetyl mercuric halides. 

When the benzene solution is treated with aqueous alcoholic iodine solution, lead tri-p-toiyl iodide is formed. 

Brazilein bears the same relationship to brazilin that hsematei n does to hsematoxylin. It is formed by oxidation of an alkaline solution of brazilin in the air and by the action of alcoholic iodine solution [11] or of nitrons acid on the same compound. 

An alcoholic iodine solution, tincture of iodine, is prepared by dissolving 10.30 g of iodine crystals in enough alcohol to make 450 mL of solution. Calculate the molarity of iodine in the solution. 

Demethylation of morphothebaine can be effected by heating with dilute hydrobromic acid at 170° C., the product being 6-hydroxyapo-morphine, which reduces silver nitrate very rapidly and is oxidized by atmospheric oxygen even more readily than apomorphine [16]. Morphothebaine and its dimethyl ether give dark green amorphous substances on oxidation with alcoholic iodine [5],...
