GLYCOL VAPORS FOR DISINFECTING PURPOSES

JAMA. 1947;133(10):696-697. doi:10.1001/jama.1947.02880100040011
Abstract

The desirability of developing a method of disinfecting air in closed and heavily contaminated spaces is unquestionable. Many procedures have been under investigation. During recent years numerous studies on the germicidal properties of vapors and mists have been published. Various substances have been employed, but through the work of O. H. Robertson and his associates and others special attention has been given to the glycols, notably propylene glycol and triethylene glycol.

Up to 1943 serious practical difficulties inhibited adequate study of glycol vapors. Robertson,1 for example, said at that time "Practical application of the use of glycol vapors for the purpose of controlling air borne infection has had to await the construction of suitable apparatus for the dispersion of glycol vapors into large and enclosed spaces and the development of an instrument to control automatically the concentration of glycol vapor in the air. Rapid progress is being made in
