ACTION AND USES: A powerful germicide, especially valuable in the form of gas for its penetrating power. Its irritant actions generally preclude its use on the body.

For disinfecting rooms, from 150 Cc. or 5 fluidounces to 1 quart or 1 liter of the official formaldehyde solution are allowed to each 1,000 cubic feet of space by various authorities. Various methods have been employed. One is to allow the solution to evaporate from sheets suspended in the tightly closed room. Another is to generate the gas in the room by treating the solution with potassium permanganate, allowing about 110 Gm. or 3-1/2 ounces of potassium permanganate to 500 Cc. or 1 pint of formaldehyde solution. A third method utilizes the reaction between formaldehyde solution and sodium dichromate in the presence of sulphuric acid, used in the proportion of 45 Cc. or 1-1/2 fluidounces of sulphuric acid and 280 Gm. or 9 ounces of sodium dichromate to 500 Cc. or 1 pint of formaldehyde solution. These methods are not effective if the temperature of the room be below 60 F. or the relative humidity below 65 per cent.
