2-Methylbutan-1-ol

Fresh air, rest.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention .

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.

TERRESTRIAL FATE: The only identifiable degradation process in soil is biodegradation. Although biodegradation data specific to 2-methyl-1-butanol are unavailable, analogy to similar aliphatic alcohols suggests that 2-methyl-1-butanol will readily biodegrade. Based upon an estimated Koc values of 15 and 120, 2-methyl-1-butanol is expected to leach readily in soil(2,SRC); however, the importance of leaching may be lessened by relatively rapid, concurrent biodegradation(SRC).

AQUATIC FATE: The only important identifiable degradation process in water is biodegradation. Although biodegradation data specific to 2-methyl-1-butanol are unavailable, analogy to similar aliphatic alcohols suggests that 2-methyl-1-butanol will be readily biodegradable. The volatilization half-lives of 2-methyl-1-butanol from a model environmental river (1 meter deep) and model pond have been estimated to be 61 hr and 28 days, respectively(1,2,SRC). Aquatic bioconcentration, hydrolysis, photodegradation and adsorption to sediment are not expected to be important(SRC).

ATMOSPHERIC FATE: Based upon a vapor pressure of 3.13 mm Hg at 25 °C(1), 2-methyl-1-butanol is expected to exist almost entirely in the vapor-phase in the ambient atmosphere(2,SRC). It will degrade in an average ambient atmosphere by reaction with photochemically produced hydroxyl radicals (estimated half-life of 47 hr)(3,SRC). Physical removal from air via wet deposition is possible since 2-methyl-1-butanol is relatively soluble in water(SRC).

Based upon a water solubility of 30,000 mg/l at 25 °C(1), the Koc for 2-methyl-1-butanol can be estimated to be 15 from a regression-derived equation(2,SRC). Based upon a measured log Kow of 1.29(3), the Koc for 2-methyl-1-butanol can be estimated to be 120 from a regression-derived equation(2,SRC). These BCF values suggest that 2-methyl-1-butanol has high to very high soil mobility(4).

2-Methyl-1-butanol has been identified as a volatile component of blue cheese aroma(1), Concord grape juice essence(2), nectarines(3), apples(4,5), papaya fruit(6), oranges(7), and tomatoes(8). 2-Methyl-1-butanol is released in the volatile emissions from poultry manure(9).

2-Methyl-1-butanol was identified as one of the odorous compounds emitted to the air from a sedimentation tank at a German water treatment facility(1). Various solvent uses of 2-methyl-1-butanol will release 2-methyl-1-butanol to air through evaporation(SRC).
