Isobutylamine

Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]:

Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

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. Give one or two glasses of water to drink. Refer for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

General First Aid:

· Wear positive pressure self-contained breathing apparatus (SCBA).

2.0 [ppm], Ceiling = 5 ppm[German Research Foundation (DFG)]

Dry chemical, foam, carbon dioxide, or alcohol foam.

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 "alcohol" foam, dry chemical or carbon dioxide.

Fireproof. Separated from strong oxidants, strong acids, food and feedstuffs

Store in refrigerator. Keep under an inert atmosphere for long-term storage. /Butyl Amines/

Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking liquid in sealable containers. Cautiously neutralize spilled liquid. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Then wash away with plenty of water.

Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Establish forced ventilation to keep levels below explosive limit. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable. /Butyl Amines/

Small Spill: Use absorbent paper to pick up spilled material. Follow by washing surfaces well with soap and water. Seal all wastes in vapor-tight plastic bags for eventual disposal.

Environmental considerations-land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Apply appropriate foam to diminish vapor and fire hazard. Neutralize with sodium bisulfate (NaHSO4).

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Incineration; Incinerator is equipped with a scrubber or thermal unit to reduce NOx emissions. Alternatively it may be poured into sodium bisulfate, neutralized and flushed with water. /n-Butylamine/

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 60(SRC), determined from a log Kow of 0.73(2) and a regression-derived equation(3), indicates that isobutylamine is expected to have high mobility in soil(SRC). The pKa of isobutylamine is 10.68(4) indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of isobutylamine from moist soil surfaces is not expected to be an important fate process given its cation state(SRC). Isobutylamine is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(6). Isobutylamine was 87 percent and 68 percent biodegraded during a 2 week incubation period using a Japanese MITI test(7), suggesting that biodegradation may occur in soils(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 60(SRC), determined from a log Kow of 0.73(2) and a regression-derived equation(3), indicates that isobutylamine is not expected to adsorb to suspended solids and sediment in water(SRC). A pKa of 10.68(4) indicates isobutylamine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Isobutylamine was 87 percent and 68 percent biodegraded during a 2 week incubation period using a Japanese MITI test(8), suggesting that biodegradation may occur in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isobutylamine, which has a vapor pressure of 138 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase isobutylamine 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 11 hours(SRC) from its estimated rate constant of 3.4X10-11 cu cm/molecule-sec at 25 °C(SRC), derived using a structure estimation method(3). Isobutylamine does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

Volatile amines /including isobutylamine were/ isolated ... from 4 month old Chanakh cheese.

The concn of various amines in 13 red and 10 white Italian wines were determined. ... The mean value for the red and white wines were 0.06 mg/L and 0.23 mg/L for isobutylamine, respectively.

Isobutylamine has been qualitatively detected in various Italian cheeses, in German wine, in American beef, in Valencia oranges, lemons from CA and cooked and boiled beef(1-6).

... The presence of volatile aliphatic amines ... in human breast milk and amniotic fluid /was measured/ to assess their role in neonatal hypergastrinemia. These volatile nitrogenous amino acid metabolites have been previously demonstrated to stimulate gastrin release in in vivo and in vitro laboratory preparations. ... The present study ... demonstrated that these gastrin-stimulatory volatile amines were present in significant concentrations in breast milk during the first several weeks after parturition and in amniotic fluid. The individual amines that were identified in both human milk and amniotic fluid samples were methylamine, dimethylamine, ethylamine, trimethylamine, propylamine, isobutylamine, and butylamine. This study provides indirect evidence to support the possibility that the hypergastrinemia measured in the fetus/neonate during the period immediately before and after birth may be attributable, in part, to the ingestion of fluid containing high concentrations of gastrin-stimulating amines.
