용도

용도

Performic Acid is used for oxidation, epoxidation and hydroxylation reactions.

처리 방법SRP: 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./LABORATORY QUANTITIES/ Wear eye protection, nitrile rubber gloves, and a laboratory coat. In the fume hood behind a shield, add to sufficient cold water to give a 5% solution of performic acid. Slowly add 20% aqueous sodium bisulfite solution until a drop of the mixture on starch-iodide paper does not produce a blue color.
Preventive MeasuresSRP: 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.
환경 거동TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that peroxyformic acid is expected to have very high mobility in soil(SRC). The estimated pKa of peroxyformic acid is 7.77(3), indicating that this compound will partially exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of peroxyformic acid from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.9X10-6 atm- cu m/mole(SRC), using a fragment constant estimation method(5). Peroxyformic acid is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 78 mm Hg at 25 °C(SRC), determined from a fragment constant method(6). Biodegradation data in soil were not available(SRC,2010).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that peroxyformic acid 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 1.9X10-6 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 15 and 110 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from an estimated log Kow of -1.62(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data in water were not available(SRC, 2010).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), peroxyformic acid, which has an estimated vapor pressure of 78 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase peroxyformic acid 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 4 days(SRC), calculated from its rate constant of 4.0X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Peroxyformic acid contains chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc of peroxyformic acid can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that peroxyformic acid is expected to have very high mobility in soil. The estimated pKa of peroxyformic acid is 7.77(3), indicating that this compound will partially exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Human Toxicity Excerpts/ALTERNATIVE and IN VITRO TESTS/ Since performic acid is used as a potent disinfectant, chemical sterilant and/or skin antiseptics, information related to its toxicity for living tissues was needed to evaluate the degree of its biotolerance and compare it to that of peracetic acid. In tests on cultured HEp-2 cells distinct cytotoxic effects occurred after treatments with 0.05% and higher concentrations. The 0.005% to 0.000,05% concentrations had only minor effects on the morphology of cells, if passaged they were capable of further growth, but were clearly inhibited in their growth ability. The lowest concentration tested (0.000005%) had no appreciable effect on HEp-2 cells. At the same concentration levels, the cells were affected to a greater degree with performic acid than with peracetic acid treatment ...
Artificial Pollution SourcesPeroxyformic acid's production and use as a chemical agent for oxidation, epoxidation, and hydroxylation reactions(1) may result in its release to the environment through various waste streams(SRC).
Environmental BioconcentrationAn estimated BCF of 3 was calculated in fish for peroxyformic acid(SRC), using an estimated log Kow of -1.62(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/SoilThe Henry's Law constant for the neutral species of peroxyformic acid is estimated as 1.9X10-6 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that peroxyformic acid is expected to volatilize from water surfaces(2). 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)(2) is estimated as 15 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 110 days(SRC). Peroxyformic acid's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Peroxyformic acid is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 78 mm Hg(SRC), determined from a fragment constant method(3).
Environmental Abiotic DegradationThe rate constant for the vapor-phase reaction of peroxyformic acid with photochemically-produced hydroxyl radicals has been estimated as 4.0X10-12 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 4 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A base-catalyzed second-order hydrolysis rate constant of 2.8X10+4 L/mole-sec(SRC) was estimated using a structure estimation method(2)this corresponds to half-lives of 4 minutes and 24 seconds at pH values of 7 and 8, respectively(2). Peroxyformic acid contains chromophores that absorb at wavelengths >290 nm(3) and therefore may be susceptible to direct photolysis by sunlight(SRC).
Probable Routes of Human ExposureOccupational exposure to peroxyformic acid may occur through inhalation and dermal contact with this compound at workplaces where peroxyformic acid is produced or used. (SRC)
