| Reactivity Alerts | Highly Flammable |
| Reactivity Profile | ISOBUTYL METHACRYLATE is an acrlate 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 polymerizes readily. (NTP, 1992) |

| 소화 절차 | If material on fire or involved in fire: Use water in flooding quantities as fog. Do not extinguish fire unless flow can be stopped. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. /Isobutyl methacrylate, stabilized/Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. /Isobutyl methacrylate, stabilized/ |
| 보관 조건 | Temp during storage must be kept low to minimize formation of peroxides and other oxidation products. ... Storage temp below 30 °C are recommended for i-Butylmethacrylate. The methacrylate monomer should not be stored for longer than one year. Isobutyl methacrylate is sensitive to UV light and should, therefore, be stored in the dark. The methacrylic ester may be stored in mild steel, stainless steel, or aluminum. |
| 정리 방법 | SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal. |

| 처리 방법 | SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 qualitypotential migration in soil or watereffects on animal and plant lifeand conformance with environmental and public health regulations.Options for the disposal of waste or spilled material: large quantities can be returned to the manufacturer for recycle. Small quantities may be incinerated under controlled conditions in incinerators suitable for methacrylates. Combustion products include carbon monoxide, carbon dioxide, and water. The product must be disposed of as special waste in accordance with regulations for special waste. |
| Preventive Measures | SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits 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.SRP: Contaminated protective clothing should be segregated in a manner that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.... Hazard is the generation of considerable exothermic heat in some of the reactions, so that high pressures & temp may develop. This danger ... should be borne in mind when designing plant. Awareness of the dangers and of good engineering design are essential to safety. Employees should be instructed about the necessity of cleansing the skin if it is contaminated by materials which are irritants or skin-absorbed. With careful design, however, and complete enclosure of those processes where toxic chemicals or intermediates occur, dangerous exposures can be avoided. /Acrylic acid & derivatives/If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. /Isobutyl methacrylate, stabilized/Personnel protection: Avoid breathing vapors. Keep upwind. Avoid bodily contact with the meterial. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amt of water or soap and water ... If contact with the material anticipated, wear appropriate chemical protective clothing. /Isobutyl methacrylate, stabilized/ |

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 1480-3920(2) indicate that isobutyl methacrylate is expected to have low to slight mobility in soil(SRC). Volatilization of isobutyl methacrylate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 5.2X10-4 atm-cu m/mole(SRC), based upon its vapor pressure, 3.63 mm Hg(3), and water solubility, 1300 mg/L(4). Isobutyl methacrylate is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Data are conflicting using standardized biodegradation tests. Utilizing the modified Japanese MITI test, isobutyl methacrylate reached 33% of its theoretical BOD after 28 days(11), while in the OECD 301D Method (Closed Bottle Test) isobutyl methacrylate was found to biodegrade 74% in 28 days(2).AQUATIC FATE: Based on a classification scheme(1), Koc values of 1480-3920(2) indicate that isobutyl methacrylate is 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 5.2X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 3.63 mm Hg(4), and water solubility, 1300 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 5.5 hours and 5.3 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 15-37 days if adsorption is considered(6). According to a classification scheme(7), an estimated BCF of 27(SRC), from its log Kow of 2.66(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Hydrolysis is not expected to be an important process(SRC) based on estimated hydrolysis half-lives of 130 and 13 years at pHs 7 and 8, respectively(10). Data are conflicting using standardized biodegradation tests. Utilizing the modified Japanese MITI test, isobutyl methacrylate reached 33% of its theoretical BOD after 28 days(11).

| Environmental Bioconcentration | An estimated BCF of 26 was calculated in fish for isobutyl methacrylate(SRC), using a log Kow of 2.66(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). |
| Volatilization from Water/Soil | The Henry's Law constant for isobutyl methacrylate is estimated as 5.2X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 3.63 mm Hg(1), and water solubility, 1300 mg/L(2). This Henry's Law constant indicates that isobutyl methacrylate 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 5.5 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 5.3 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 15-37 days if adsorption is considered(4). Isobutyl methacrylate's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of isobutyl methacrylate from dry soil surfaces may exist(SRC) based upon its vapor pressure(1). |

| Environmental Abiotic Degradation | The rate constant for the vapor-phase reaction of isobutyl methacrylate with photochemically-produced hydroxyl radicals has been estimated as 2.3X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 17 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of isobutyl methacrylate with ozone has been estimated as 1.1X10-17 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 1 day at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). A base-catalyzed second-order hydrolysis rate constant of 1.8X10-3 L/mole-sec(SRC) was estimated using a structure estimation method(3)this corresponds to half-lives of 130 and 13 years at pH values of 7 and 8, respectively(3). Isobutyl methacrylate 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). |
