Processes for removing monochloropropanediols and/or glycidol from glycerol are disclosed. Starting glycerol is subjected to treatment with alkali, heat under vacuum, steam, ion exchange resins, or solids to reduce the level of monochloropropanediol. Glycerol compositions low in monochloropropanediol and glycidol are obtained thereby. These compositions may be suitable for food grade glycerol or for modification into food and chemicals.
