Alcohols, C7-9-branched, C8-rich Safety Data Sheets

Hazardous to the aquatic environment, long-term (Chronic) - Category Chronic 2

If inhaled

Following skin contact

Following eye contact

Following ingestion

Anesthesia, nausea, headache, dizziness; mildly irritating to skin and eyes. (USCG, 1999)

This chemical is combustible. (NTP, 1992)

Wear self-contained breathing apparatus for firefighting if necessary.

Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.

Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Use personal protective equipment. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas.

Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Separated from strong oxidants and strong bases. Store in an area without drain or sewer access. Ventilation along the floor.Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide.2-ETHYL HEXANOL 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. This compound is incompatible with strong oxidizing agents and strong acids. (NTP, 1992)

AEROBIC: 2-Ethylhexanol, present at 100 mg/L, reached 89.5% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In BOD tests, 100% degradation occurred in 24 hours using an industrial wastewater (acclimated) inoculum, while no degradation occurred after 24 hours and 100% degradation occurred after 135 hours using a municipal wastewater (unacclimated) seed(2). In a BOD test using a sewage seed, 26%, 75%, 78%, and 86% of 2-ethylhexanol's theoretical BOD was exerted after 5, 10, 15, and 20 days, respectively(3). When the test was repeated in synthetic seawater, the respective results were 58%, 64%, 84%, and 100% of the theoretical BOD consumed(3). After 5 days, 41.5% of theoretical BOD was consumed using an inoculum of mixed microbial cultures(4). 2-Ethylhexanol was degraded 31% when incubated with soil from a waste disposal site for 21 days; 52% degradation occurred when the sample was amended with a source of nitrogen(5). When 2-ethylhexanol was added to river water at 18-19 deg C, it started to degrade after a 3-4 day lag, after 8 and 9 days the theoretical BOD consumed was 30% and 59%, respectively(6).

An estimated BCF of 30 was calculated in fish for 2-ethylhexanol(SRC), using an estimated log Kow of 2.73(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2-ethylhexanol can be estimated to be 35(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-ethylhexanol is expected to have very high mobility in soil.
