Abstract
22,136. Lutze, F. Sept. 27. Disinfectants.-Carbolic acid is prepared, in the form of a powder having no hygroscopic properties, by mixing with crystallized carbolic acid a water binding-agent, which has no chemical action upon the carbolic acid, and does not liquefy through absorption of water, and then drying and pulverizing the mixture. For this purpose, there may be used anhydrous boracic acid, arsenic trioxide, or basic anhydrides, such as aluminium oxide, or magnesium oxide, or dehydrated salts, such as calcined borax or alum, or the dehydrated salts of phosphoric acid, pyrophosphoric acid, and metaphosphoric acid.
