Title: Improved process for preparing stable disinfecting agents
IPC: A01N59/16
Filed: 1938-06-07
Abstract: 515,504. Disinfectants. SCHOENBERG, G. June 7, 1938, No. 16946. [Class 81(i)] Stable disinfecting agents are prepared from acid thiocyanates, or their solutions by adding thereto small quantities of metals or metal compounds which prevent the development of hydrogen'sulphide, .especially those the metals of which are capable of forming sulphides which are difficultly soluble in acids, e.g. copper, silver, mercury, bismuth, lead, m�lybdic acid and chromium sexquoxide are also suitable additions. According to examples, sodium thiocyanate and potassium bisulphate are dissolved in water, a small quantity of copper sulphate crystals or metallic copper or molybdenum trioxide being added to the resulting solution. Alternatively, the metal or metal compound may be added, instead of to the solutions, to the dry mixture of thiocyanate and acid salt, or to one of the constituents of the, mixture or the solution to be prepared. If the disinfecting agent is to be used in conjunction with a vegetable mucilage, the quantity of the additions should be increased considerably. A suitable mucilage is tragacanth with or without glycerine. The tragacanth may be mixed with boric acid and finely rubbed with glycerine, the product being then dissolved in water with the addition of a concentrated thiocyanate solution. The solution is then adjusted to a pH of 1.7 by the addition of sodium bisulphate, hydrochloric acid, phosphoric acid or the like, the solution then being stabilized by the addition of a small quantity of copper sulphate.
