More Information
Summary:A process for semiquantitative colorimetric detection of organic peroxides, especially ether peroxides, with the aid of peroxide indicating means comprising an absorbent carrier impregnated with peroxides, a colorimetric indicator, optionally a buffer, and optionally other additives. The indicating means is immersed in a solution of peroxides in a volatile organic solvent having a boiling point of below 80 DEG C., preferably of below 50 DEG C., and withdrawn. The indicating means is placed in a water vapor atmosphere having a relatively constant temperature between about 20 and 100 DEG C. to evaporate the organic solvent and deposit moisture on the surface thereof, and then examined for color change.
