Method for removing a hydrogen cyanide contaminant from an organic liquid and method for detecting hydrogen cyanide impurities in a organic liquid

摘要

The present invention provides a method for removing hydrogen cyanide from a hydrogen cyanide-contaminated organic liquid comprising the steps of contacting the hydrogen cyanide-contaminated organic liquid with a metal alkoxide to generate a metal cyanide salt and an alkanol and then separating the organic liquid from the metal cyanide salt and the alkanol. The present invention also provides a method for detecting hydrogen cyanide impurities in an organic liquid.
