Highly Flammable
ETHYL FORMATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids [Note: Decomposes slowly in water to form ethyl alcohol and formic acid.] (NIOSH, 2016).

This was attributed to extreme instability of the ester in presence of the base, leading to the reverse reaction with vigorous evolution of carbon monoxide. Immediate neutralization of the reaction mixture would prevent the decomposition, which also occurs with ethyl formate and base.

Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk.

SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.|Any clothing which becomes wet with liquid ethyl formate should be removed immediately and not reworn until the ethyl formate is removed from the clothing.|SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|The worker should immediately wash the skin when it becomes contaminated.|For more Preventive Measures (Complete) data for ETHYL FORMATE (6 total), please visit the HSDB record page.

/IT IS/ REPORTED IN OIL OF BORONIA DENTIGEROIDES. IT HAS BEEN IDENTIFIED IN FLORIDA ORANGE JUICE, SEVERAL VARIETIES OF HONEY, APPLES AND PEARS, & DISTILLED LIQUORS, SUCH AS RUM.|Ethyl formate occurs widely in fruit(1).
Ethyl formate maybe released to the environment as a result of its production, transport, disposal and use as a synthetic flavoring agent in lemonades, chewing gum, ice cream, essences (apple, pineapple, banana, and peach flavors), artificial rum and arrac; as a fungicide and larvicide for tobacco, cereals, dried fruit, and other crops(1,3) and as a solvent for cellulose nitrate and acetate, as an acetone substitute and fumigant in packaged food, and in organic synthesis(2-4).
TERRESTRIAL FATE: If released to soil, ethyl formate would readily volatilize from the surface layers of soil as well as leach. While no data were located concerning the degradation in soil, it would be expected to readily degrade by chemical hydrolysis, especially in alkaline soil, and biodegrade. (SRC)|AQUATIC FATE: Ethyl formate has a relatively high Henry's Law constant of 3.85X10-4 atm-cu m/mol(1) and if released to water, it will be lost due to evaporation. A volatilization half-life of 4.5 hrs was predicted for ethyl formate from a model river 1 m deep, flowing at 1 m/sec with a wind velocity of 3 m/sec(2,SRC). It would not be expected to sorb to sediment or bioconcentrate in aquatic organisms. Chemical hydrolysis will be an important fate process, especially in alkaline waters. The hydrolytic half-life is 3.1 days and 7.5 hr at pH 7 and 8, respectively(3,SRC). Based on limited data from screening tests supplemented by predictions of mathematical models and data on similar chemicals, ethyl formate should rapidly biodegrade(SRC).|ATMOSPHERIC FATE: The half-life of ethyl formate in the atmosphere is estimated to be 11 days as a result of reaction with photochemically-produced hydroxyl radicals(1). Being fairly soluble in water, it should be readily washed out of the air by rain(SRC).
Ethyl formate hydrolyzes by an acid- or base-catalyzed reaction, although the base- catalyzed reaction is faster(4). The alkaline hydrolysis rate constant for ethyl formate is 25.7 L/mol-sec at 25 degC(3). The corresponding hydrolysis half-lives are 3.1 days and 7.5 hr at pH 7 and pH 8, respectively(SRC). The hydrolysis products are formic acid and ethanol(1). In the atmosphere, ethyl formate reacts with photochemically-produced hydroxyl radicals with a rate constant of 1.02X10-12 cu cm/molecule-s(1). Assuming a hydroxyl radical concn of 5X10+5 radicals/cu cm, the half-life of ethyl formate in the atmosphere would be 11 days(SRC).
Ethyl formate did not bioconcentrate in rainbow trout(1). Using a reported log octanol/water partition coefficient of 0.23(2), a BCF of 0.88 is estimated using a regression equation giving additional indication that ethyl formate should not bioconcentrate in aquatic organisms.
Using a reported water solubility of 88.25 g/L(1) for ethyl formate, an estimated Koc of 8 was calculated using a regression equation(2,SRC). A Koc of 4 was estimated from molecular structure(3). According to a suggested classification scheme(3), this estimated Koc suggests that ethyl formate will be highly mobil in soil (SRC).
Using a reported Henry's Law constant of 3.85X10-4 atm-cu m/mol(1) a volatilization half-life of 4.5 hrs was predicted for ethyl formate from a river 1 m deep, flowing at 1 m/sec with a wind velocity of 3 m/sec(2,SRC). Similarly, its volatilization half-life from a model lake 1 m deep, with a 0.05 m/s current and a 0.5 m/s wind is estimated to be 4.0 days(2). Ethyl formate has a high vapor pressure, 244.6 mm Hg at 25 °C(3) and therefore would readily volatilize from dry soil and other surfaces(SRC). Its moderately high Henry's Law Constant coupled with it low adsorptivity to soil indicates that ethyl formate would also readily volatilize from moist soil(SRC).
Ethyl formate was identified, but not quantified, in roasted filberts(1), beer(2), wine(6,7), Korean chamchwi(3), blue cheese(4), and apples and pears(5).
Ethyl formate is used in flavorings for lemonades and essences, in artificial rum and arrac, and as a fungicide and larvicide for tobacco, cereals, dried fruits, and other crops(1). It is also naturally found in fruits. Oral ingestion may occur as a result of the above reported uses of ethyl formate(SRC). Occupational exposure will be via inhalation and dermal contact(SRC).|NIOSH (NOES Survey 1981-1983) has statistically estimated that 8,149 workers are exposed to ethyl formate in the USA(1).

Inhalation of vapor causes slight irritation of the eyes and rapidly increasing irritation of the nose. High concentrations cause deep narcosis within a few minutes followed by death within a few hours. Contact with liquid causes moderate irritation of eyes and mild irritation of skin. Ingestion causes irritation of mouth and stomach; may cause deep narcosis and death if not treated. (USCG, 1999)
Eye: If this chemical contacts the eyes, immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical. Skin: If this chemical contacts the skin, immediately flush the contaminated skin with water. If this chemical penetrates the clothing, immediately remove the clothing and flush the skin with water. Get medical attention promptly. Breathing: If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform mouth-to-mouth resuscitation. Keep the affected person warm and at rest. Get medical attention as soon as possible. Swallow: If this chemical has been swallowed, get medical attention immediately. (NIOSH, 2016)|(See procedures)

Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). It is also known as ethyl methanoate because formic acid is also known as methanoic acid. Ethyl formate has the characteristic smell of rum and is also partially responsible for the flavor of raspberries. It occurs naturally in the body of ants and in the stingers of bees.
