Absorb on paper. Evaporate on a glass or iron dish in hood. Burn the paper.

Countermeasures recommended for treating spills: activated charcoal, biological treatment agent, gelling agent, absorbing agent, dispersing agent.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

1. By absorbing it in vermiculite, dry sand, earth or a similar material and disposing in an ... /approved/ sanitary landfill. 2. By atomizing in a suitable combustion chamber.

The following wastewater treatment technologies have been investigated for n-propanol: Biological treatment.

Incineration: Waste liquid can be atomized in an incinerator or can be disposed of by way of a licensed solvent disposal company or can be reclaimed.

n-Propanol was detected in 1 of 12 samples of mother's milk from 4 urban areas in the United States(1). The avg and range of n-propanol concns in human breath due to metabolic processes is 130 ug/cu-m and not detected-1,270 ug/cu m (8 subjects in zero air), respectively (2).

CUTANEOUS REACTIONS TO N-PROPANOL WERE EVALUATED IN A CONTROL GROUP & IN PATIENTS BEFORE & DURING RECEIPT OF DISULFIRAM THERAPY. LOCAL CUTANEOUS ERYTHEMA WAS OBSERVED FROM PATCH TESTS WITH N-PROPANOL IN HYDRATED SKIN. SINCE REACTIONS NOTED FROM TOPICALLY APPLIED ALCOHOLS BEFORE & DURING DISULFIRAM THERAPY WERE NOT STATISTICALLY DIFFERENT, A LOCALIZED DISULFIRAM-ALCOHOL REACTION IS UNLIKELY. ERYTHEMA RESULTING FROM TOPICALLY APPLIED ALCOHOLS OCCURRED IN A DOSE RELATED MANNER & WAS CAUSED BY A DIRECT VASODILATORY EFFECT ON THE CUTANEOUS MICROVASCULATURE.

TERRESTRIAL FATE: Based on a classification scheme(1), a Koc value of 33(SRC) determined from a log Kow of 0.25(2), and a regression-derived equation(3), indicates that n-propanol is expected to have very high mobility in soil(SRC). Volatilization of n-propanol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 7.41X10-6 atm-cu m/mole(4). The potential for volatilization of n-propanol from dry soil surfaces may exist(SRC) based upon a vapor pressure of 21 mm Hg(5). n-Propanol is readily degraded in aerobic systems(6-9); the range of half-lives for aerobic degradation using a sewage sludge inoculum are <1 day to 11 days(SRC). n-Propanol has also been shown to be readily degraded under anaerobic conditions(9).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 33(SRC), determined from an measured log Kow of 0.25(2) and a regression-derived equation(3), indicates that n-propanol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 7.41X10-6 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 62 hours and 31 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC) from a log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). n-Propanol is readily degraded in aerobic systems(7-10); the range of half-lives for aerobic degradation using a sewage sludge inoculum are <1 day to 11 days(SRC). n-Propanol has also been shown to be readily degraded under anaerobic conditions(10).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-propanol, which has a vapor pressure of 21.0 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase n-propanol 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 2.9 days(SRC), calculated from its rate constant of 5.53X10-12 cu cm/molecule-sec at 25 °C(3).

Alcoholic beverages nearly always contain n-propanol as a product of fermentation(1). Beer contains up to 195 mg/l, wine up to 116 mg/l, various types of spirits up to 3520 mg/l, and neat ethanol up to 2910 mg/l(1). n-Propanol is present at low levels as a flavor volatile in a variety of foodstuffs and non-alcoholic drinks, eg: kefir culture, cream culture, filberts (roasted), raw milk, heat-treated milk, Kumazasa Sasa albomarginata, heated triolein, boiled buckwheat flour, tomato (ripe, juice, puree, and paste), Kogyoku apple, apple and apple juice, white bread, butter, cheddar/Swiss cheese, soy sauce, fish sauce, pigweed, winged bean (raw/roasted), soybean (raw, roasted), potato tuber, roasted watermelon seeds, babco fruit, tilsit cheese, endive, Valancia orange juice(1).n-Propanol was identified in fermentation brine of pimentos used for stuffing olives(2). n-Propanol was found in 31 commercial brines - 180 to 380 mg n-propanol/l ethyl alcohol; Cahors wine: 33 mg n-propanol/l wine; Corbiers wine: 12 mg n-propanol/l wine; Jamaican Rum: 31,300 mg n-propanol/l ethyl alcohol(2). The mean concn of n-propanol in headspace volatiles of Cabernet Sauvignon wines from the Napa Valley, CA ranged from 0.001 to 0.778 mg/l(3). n-Propanol has been detected (not quantified) in milk products including kefir and yogurt, and traces have been detected in fermented eggs(4). The range of concns of n-propanol in the volatile components of orange juices were 50-1140 ppb(5).

Propyl alcohol is an indirect food additive for use only as a component of adhesives.

Normal propyl alcohol may be safely used in feeds and feed supplements for cattle as a source of metabolizable energy. It is incorporated in the fed or feed supplement in an amount which provides not more than 54.5 g of the additive per head per day.

Residues of n-propanol are exempted from the requirement of a tolerance when used as a solvent or cosolvent in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest.

n-Propanol is exempted from the requirement of a tolerance when used as a solvent for blended emulsifiers in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only.

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. n-Propyl alcohol is produced, as an intermediate or a final product, by process units covered under this subpart.

It is by-product of the synthesis of methyl alcohol by high pressure & in the propane/butane oxidation process.

The production of n-propanol by hydroformulation or oxo technology is a two step process in which ethylene is first hydroformulated to propanal; the resulting propanal is hydrogenated to n-propanol.

n-Propanol is one of the products from Sasol's Fischer-Tropsch process. Coal is gasified...to produce synthesis gas /which is catalyzed by a powdered iron-based catalyst to produce/ a mixture of hydrocarbons and oxygenates. The alcohol streams are further purified by distillation to yield pure n-propanol.
