no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

Combustible when it is exposed to heat or flame.DODECANOL 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.

12.2 Persistence and degradability

AEROBIC: A 5-day theoretical BOD of 20% was observed for 1-dodecanol in an aerobic screening test using a sewage inoculum(1). A 5-day theoretical BOD of 23.2% was observed for 1-dodecanol in a standard BOD dilution test using a mixed microbial inoculum(2-3). A 5-day theoretical BOD of 27-29.7% was observed for 1-dodecanol in a standard BOD aerobic screening test using a sewage inoculum or an acclimated activated sludge inoculum(4); using a Warburg respirometer technique and a sewage inoculum, a 6-hr theoretical BOD of 15.2% was observed(4). Using a Warburg respirometer technique and various activated sludge inoculum, respective 6-hr, 12-hr and 24-hr theoretical BODs of 4.5, 10.1 and 13.4% were observed(5). 1-Dodecanol was found to be readily biodegraded(6).

12.3 Bioaccumulative potential

An estimated BCF of 48 was calculated in fish for 1-dodecanol(SRC), using a log Kow of 5.13(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
