10.3 Possibility of hazardous reactions

Highly flammable liquid and vapor.The vapour mixes well with air, explosive mixtures are easily formed.Attacks plastics. [Handling Chemicals Safely 1980. p. 236]. Acetyl bromide reacts violently with alcohols or water [Merck 11th ed. 1989]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: an explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid [Chem. Eng. News 45(43):73 1967; J, Org. Chem. 28:1893 1963]. Alkyl hypochlorites are violently explosive. They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. Chlorine plus alcohols would similarly yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M 1991]. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: t-Butyl alcohol, present at 100 mg/L, achieved 2.5% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). The biodegradation half-life of t-butyl alcohol was reported to range from about 28 to 180 days in aerobic water and 100 to 500 days in anaerobic water(2). t-Butyl alcohol reached 1% of its theoretical BOD using a sewage sludge during a 5 day incubation period(3). Using a river die-away test, t-butyl alcohol achieved 4% of its theoretical BOD in 12 days(4). t-Butyl alcohol, present at 50 mg/L, achieved 7% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5). Approximately 96% dissolved organic carbon was removed over a 6 day incubation period using the Zahn-Wellens test, meant to simulate degradation at an industrial sewage treatment plant(5). Using an activated sludge in a prolonged closed bottle biodegradation test, t-butyl alcohol was degraded 10, 63 and 67% in 28, 42 and 56 days, respectively(6). Biodegradation of t-butyl alcohol in unamended soils collected at different depths had rates of <0.01 to 0.15 mg/L/day/gram dry soil(7).

12.3 Bioaccumulative potential

BCF values of <5 were reported for carp exposed to 6 ug/L of t-butyl alcohol during a 6 week incubation period(1). According to a classification scheme(2), this BCF suggests bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of t-butyl alcohol has been reported as 37 (log Koc 1.57)(1-2). According to a classification scheme(3), this Koc value suggests that t-butyl alcohol is expected to have very high mobility in soil.

12.5 Other adverse effects

Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air.

Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Will be easily ignited by heat, sparks or flame.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. For large fires, use water spray, fog, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Water may be ineffective. Use agent most appropriate to extinguish fire. Do NOT use straight streams of water.

  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Ground and bond containers when transferring material. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
