Description

• Nonanol appears as colorless liquid with a rose or fruity odor. Floats on water. Freezing point 23 °F. (USCG, 1999)
  CAMEO Chemicals
• Nonan-1-ol is a nonanol that is nonane substituted by a hydroxy group at position 1. It has been isolated as a component of volatile oils from plants like Hordeum vulgare. It has a role as a volatile oil component, a flavouring agent, an antifungal agent and a plant metabolite. It is a primary alcohol and a nonanol.

6Accidental release measures

Isolation and evacuation

• Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary. FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Spill cleanup

• AEROBIC: Nonyl alcohol degraded fast in aerobic biodegradation screening tests(1-3). In one 5-day BOD test using acclimated mixed cultures, 47.9% of theoretical BOD was consumed(1). In the other test which used an activated sludge inoculum, nonyl alcohol's half-life was 1.2 days(SRC), calculated from a biodegradation rate of 2.36X10-2/hr(3). In a third test, 62% of its theoretical BOD in a grab sample of freshwater incubated at 18-19 °C was expended in 4 days(2).

9Physical and chemical properties

10Stability and reactivity

Reactivity

• NONANOL is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
  CAMEO Chemicals
• No rapid reaction with air. No rapid reaction with water.

12Ecological information

Environmental fate

• 1-Nonanol's production and use in perfumery and as a flavoring ingredient may result in its release to the environment through various waste streams. 1-nonanol is also a plant volatile and has been identified in several foods. If released to air, a vapor pressure of 2.27X10-2 mm Hg at 25 °C indicates 1-nonanol will exist solely as a vapor in the atmosphere. Vapor-phase 1-nonanol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 28 hours. If released to soil, 1-nonanol is expected to have moderate mobility based upon an estimated Koc of 290.

13Disposal considerations

• SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
