Ketones

Highly Flammable

Ketones, such as 5-METHYLHEXAN-2-ONE, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

Do not breathe gas, fumes, vapor, or spray.|SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.|If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away.

5-Methyl-2-hexanone's production and use as a solvent for high-solids coatings(1), nitrocellulose, cellulose acetate, acrylics and vinyl copolymers(2) will result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 250(SRC), determined from a log Kow of 1.88(2) and a regression-derived equation(3), indicates that 5-methyl-2-hexanone is expected to have moderate mobility in soil(SRC). Volatilization of 5-methyl-2-hexanone from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.6X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 5.77 mm Hg(4), and water solubility, 5400 mg/L(5). 5-Methyl-2-hexanone is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Biodegradation data were not available(SRC, 2007).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 250(SRC), determined from a log Kow of 1.88(2) and a regression-derived equation(3), indicates that 5-methyl-2-hexanone is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 1.6X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 5.77 mm Hg(4), and water solubility, 5400 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 10 hours and 6.2 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 6(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data were not available(SRC, 2007).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 5-methyl-2-hexanone, which has a vapor pressure of 5.77 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 5-methyl-2-hexanone is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 37 hours(SRC), calculated from its rate constant of 1.0X10-11 cu cm/molecule-sec at 25 °C(3). 5-Methyl-2-hexanone contains chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).

The rate constant for the vapor-phase reaction of 5-methyl-2-hexanone with photochemically-produced hydroxyl radicals has been measured as 1.0X10-11 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 37 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). 5-Methyl-2-hexanone is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(2). 5-Methyl-2-hexanone contains chromophores that absorb at wavelengths >290 nm(2) and therefore may be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 6 was calculated in fish for 5-methyl-2-hexanone(SRC), using a log Kow of 1.88(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

The Koc of 5-methyl-2-hexanone is estimated as 250(SRC), using a log Kow of 1.88(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 5-methyl-2-hexanone is expected to have moderate mobility in soil.

The Henry's Law constant for 5-methyl-2-hexanone is estimated as 1.6X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 5.77 mm Hg(1), and water solubility, 5400 mg/L(2). This Henry's Law constant indicates that 5-methyl-2-hexanone is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 10 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 6.2 days(SRC). 5-Methyl-2-hexanone's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 5-methyl-2-hexanone from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

5-Methyl-2-hexanone was detected not quantified as a volatile component of roasted filberts(1), fried bacon(2), cooked beef(3) and cooked pork(3).

Exposure to methyl isoamyl ketone in the workplace is most likely to occur by skin contact, eye contact, or inhalation, particularly at elevated temperatures.|NIOSH (NOES Survey 1981-1983) has statistically estimated that 18,834 workers (4,071 of these are female) are potentially exposed to 5-methyl-2-hexanone in the US(1). Occupational exposure to 5-methyl-2-hexanone may occur through inhalation and dermal contact with this compound at workplaces where 5-methyl-2-hexanone is produced or used(SRC). 5-Methyl-2-hexanone was detected in the air of a fur tanning facility in New York at concentrations below the OSHA exposure limits(2). Monitoring data indicate that the general population may be exposed to 5-methyl-2-hexanone via ingestion of food(SRC).
