ISOBUTYL ACRYLATE is an acrylate 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. Polymerizes readily in the presence of heat and light generating much heat; reacts with strong oxidants.

Isobutyl acrylate's production and use as a comonomer in acrylic surface coatings, an intermediate for the production of polymers and as the monomer in synthetic resin manufacture(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 66(SRC), determined from a water solubility of 2,000 mg/L(2) and a regression-derived equation(3), indicates that isobutyl acrylate is expected to have high mobility in soil(SRC). Volatilization of isobutyl acrylate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 6.0X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 7.07 mm Hg(4), and water solubility(2). Isobutyl acrylate is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). By analogy to butyl acrylate, which reached 61% of its theoretical BOD in 2 weeks using an activated sludge inoculum in the Japanese MITI test(5), biodegradation of isobutyl acrylate may by an important environmental fate process in soil(SRC).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 66(SRC), determined from a water solubility of 2,000 mg/L(2) and a regression-derived equation(3), indicates that isobutyl acrylate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 6.0X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 7.07 mm Hg(4), and water solubility(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 4.6 hours and 117 hours, respectively(SRC). According to a classification scheme(5), an estimated BCF of 10(SRC), from a log Kow of 2.22(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). No hydrolysis data were available for isobutyl acrylate. A base-catalyzed second-order hydrolysis rate constant of 1.33X10-2 L/mole-sec(SRC) was estimated using a structure estimation method(8); this corresponds to half-lives of 1.6 years and 16.5 years at pH values of 8 and 7, respectively(8). By analogy to butyl acrylate, which reached 61% of its theoretical BOD in 2 weeks using an activated sludge inoculum in the Japanese MITI test(9), biodegradation of isobutyl acrylate may by an important environmental fate process in water(SRC).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isobutyl acrylate, which has a vapor pressure of 7.07 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase isobutyl acrylate 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 1.2 days(SRC), calculated from its rate constant of 1.4X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). The rate constant for the vapor-phase reaction of isobutyl acrylate with ozone has been estimated as 0.18X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(4). This corresponds to an atmospheric half-life of about 6.5 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(5).

The rate constant for the vapor-phase reaction of isobutyl acrylate with photochemically-produced hydroxyl radicals has been estimated as 1.4X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 1.2 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of isobutyl acrylate with ozone has been estimated as 0.18X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(1). This corresponds to an atmospheric half-life of about 6.5 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). No hydrolysis data are available for isobutyl acrylate(SRC). However, hydrolysis of isobutyl acrylate may be a significant process under alkaline conditions based upon a hydrolytic half-life of 4 hours at pH 11 for the structurally similar butyl acrylate(3); half-lives for butyl acrylate at pH 7, 8, and 9 were 4 years, 150 days, and 15 days(SRC), respectively, based upon a hydrolytic rate constant of 0.053 L/mole-sec(4). A base-catalyzed second-order hydrolysis rate constant of 1.33X10-2 L/mole-sec(SRC)was estimated using a structure estimation method(5); this corresponds to half-lives of 1.6 years and 16.5 years at pH values of 8 and 7, respectively(5).Isobutyl acrylate is not expected to directly photolyze in sunlight(SRC) based upon the lack of absorption of light at wavelengths >290 nm by the structurally similar ethyl acrylate(6).

An estimated BCF of 10 was calculated in fish for isobutyl acrylate(SRC), using a log Kow of 2.22(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

The Koc of isobutyl acrylate is estimated as 66(SRC), using a water solubility of 2,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isobutyl acrylate is expected to have high mobility in soil.

The Henry's Law constant for isobutyl acrylate is estimated as 6.0X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 7.07 mm Hg(1), and water solubility, 2,000 mg/L(2). This Henry's Law constant indicates that isobutyl acrylate is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 4.6 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 5 days(SRC). Isobutyl acrylate's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of isobutyl acrylate from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

Occupational exposure to isobutyl acrylate may occur through dermal contact with this compound at workplaces where isobutyl acrylate is produced or used. (SRC)
