Iodine paint, compound

Ethyl alcohol is an important organic solvent. It is used in the preparation of tincture of iodine, paints, essences, perfumes and cosmetics. It is also found in drinks, spirit and cologne. Ethyl alcohol is the starting substance for most organic compounds. 

The compounds may have either the formula H3PO4 (m.p., 40°) or 2H3P04-H20 (m.p., 30°). In a round-bottomed flask of suitable size, place 1 part of white phosphorus and 16 parts of nitric acid of sp. gr. 1.2 together with a few crystals of iodine as a catalyzer. Provide the flask with a reflux condenser, painting the cork with black asphalt paint to protect it from the action of the nitric acid. Heat until all of the phosphorus has dissolved then distill off most of the liquid and pour the residue into an open dish. Evaporate with several additions of concentrated nitric acid to oxidize all lower acids of phosphorus and finally concentrate in a platinum dish until the temperature of the solution reaches 150°. On cooling, if necessary with a freezing mixture, the liquid can be brought to crystallization. The crystals should be dried over phosphorus pentoxide...

Addition of organic impurities such as methyl ethyl keton (MEK), a common paint solvent, to an aqueous I solution in the absence of radiation proved not to result in a measurable organoiodide formation. Under the influence of radiation, however, addition of MEK leads to an increase in the total airborne iodine concentration by more than an order of magnitude over a period of several hours, corresponding to a decrease of the steady-state iodine partition coefficient from 10 to 10 in the absence of MEK to about 10 after addition of this compound (Fluke et al., 1991). 

The victim, usually by accident, ingests a strong acid, caustic alkali, iodine, or solvent. In the average American home, these chemicals include the powerful cleaning detergents, drain openers, automatic dishwasher compounds, ammonia, paint thinner, turpentine, kerosene, and gasoline.
