Procedure
For Water Soluble Compounds: To 1 mL of the ceric ammonium reagent add 4 to 5 drops of a liquid unknown or 0.1-0.2 g of a solid. Mix thoroughly and note if the yellow color of the reagent changes to red. Alcohols react with the reagent to form a red alkoxy cerium(IV) compound. If a red color develops, watch the solution carefully and note the time for the mixture to become colorless. If no change is noted in 15 min, the test tube may be stoppered and allowed to stand several hours or overnight. Also note if bubbles of carbon dioxide are liberated.
For Water Insoluble Compounds: Add 4 mL of dioxane to 2 mL of the ceric ammonium nitrate reagent. If a red color develops or if the solution becomes colorless, the dioxane must be purified. If the mixture remains yellow or is only a light orange-yellow, it may be used to test water insoluble compounds. Divide the 6 mL of the solution in half, reserving 3 mL for observation as a control. To the other 3 mL of the dioxane containing reagent, add 4 or 5 drops of a liquid unknown or 0.1-0.2 g of a solid. Mix thoroughly and make the same observations as above.
Ceric Ammonium Nitrate Reagent: Add 1.3 mL of concentrated nitric acid to 40 mL of distilled water and then dissolve 10.96 g of yellow ceric ammonium nitrate in the dilute nitric acid solution. After the solid has dissolved, dilute to 50 mL.
Positive Test
Formation of a red alkoxy cerium(IV) compound is a positive test.
Phenols give a brown color or precipitate as a positive test.
complication
Hot solutions of Ce(IV) oxidize many organic compounds.

3. Hazards Identification
Emergency Overview -------------------------- DANGER! STRONG OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. SAF-T-DATA(tm) Ratings (Provided here for your convenience) ----------------------------------------------------------------------------------------------------------- Health Rating: 2 - Moderate Flammability Rating: 0 - None Reactivity Rating: 3 - Severe (Oxidizer) Contact Rating: 2 - Moderate Lab Protective Equip: GOGGLES & SHIELD; LAB COAT & APRON; VENT HOOD; PROPER GLOVES Storage Color Code: Yellow (Reactive) ----------------------------------------------------------------------------------------------------------- Potential Health Effects ---------------------------------- Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. Ingestion: Large doses of nitrates may cause dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, convulsions, and collapse. Skin Contact: Causes irritation to skin. Symptoms include redness, itching, and pain. Eye Contact: Causes irritation, redness, and pain. Chronic Exposure: Under some circumstances methemoglobinemia occurs in individuals when the nitrate is converted by bacteria in the stomach to nitrite. Nausea, vomiting, dizziness, rapid heart beat, irregular breathing, convulsions, coma, and death can occur should this conversion take place. Aggravation of Pre-existing Conditions: No information found.
4. First Aid Measures
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Ingestion: Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
5. Fire Fighting Measures
Fire: Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. This oxidizing material can increase the flammability of adjacent combustible materials. Explosion: Contact with oxidizable substances may cause extremely violent combustion. Sensitive to mechanical impact. Fire Extinguishing Media: Water spray. Special Information: Wear full protective clothing and breathing equipment for high-intensity fire or potential explosion conditions.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Separate from combustible, organic, or any other readily oxidizable materials. Isolate from incompatible substances. Do not store on wooden floors. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established. Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details. Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
