火災危険Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
有害性の概要No evidence of carcinogenicity in mice or ratsEmergency treatment: Triazine herbicidesTriazine herbicides have a low level of toxicity to mammals. Toxicity is more likely to be due to other ingredients in the formulation, e.g. the solvents. [HSDB] A mild eye irritant[ICSC] Not irritating to skin and slightly irritating to eyes of rabbitsEdema in the forestomach was the major toxicity observed in acute oral lethal-dose studyEffects on liver observed (increased enzymes) in repeated dose gavage study of ratsNOAEL for repeated dose toxicity was 20mg/kg/dayNot mutagenic in vivoNOAELs for reproductive toxicity were 100 mg/kg/day for males (highest dose tested), 4 mg/kg/day for females (lack of nursing activity), and 20 mg/kg/day for offspring (decreased birth index and body weight)No external abnormalities observed in pups[OECD SIDS: 2,4-Diamino-6-phenyl-1,3,5-triazine - 2001] An irritant[Alfa Aesar MSDS]The major hazards encountered in the use and handling of 2,4-diamino-6-phenyl-1,3,5-triazine stem from its toxicologic properties. Toxic by inhalation and ingestion, exposure to this crystalline substance may occur from its use in the manufacture of thermosetting resins, and as a chemical intermediate for pesticides, pharmaceuticals, and dyestuffs. In activities and situations where over exposure may occur, wear a self-contained breathing apparatus and personal protective clothing. If contact should occur, immediately flush affected skin or eyes with running water for at least 15 minutes. Remove contaminated clothing and shoes at the site. While this substance does not ignite easily, it may burn with the production of irritating and poisonous gases. For fires involving this substance, extinguish with dry chemical, CO2, Halon, water spray, fog, or standard foam. This substance may be shipped via air, rail, road, and water, in containers bearing the label "Poison". Small dry spills of this substance may be placed into a clean, dry, covered container for later disposal (liquid solutions are first absorbed in sand or other noncombustible absorbent). Large liquid spills should be diked far ahead to prevent this substance from entering water sources and sewers. Before implementing land disposal of this substance, consult with regulatory agencies for guidance.

製法・合成法

製造方法

Benzoguanamine closely resembles melamine in that reaction with formaldehyde gives methylol derivatives and then resinous condensates. Butylated benzoguanamine-formaldehyde resins have found some use in surface coatings. In a typical preparation, benzoguanamine (1 mole) is heated with formalin (3 mole formaldehyde) at pH 8.3 and 70-80°C until the guanamine has dissolved. n-Butanol (9 mole) and a small amount of hydrochloric acid are added and the azeotrope distilled off until removal of water is complete. Like their melamine counterparts, butylated benzoguanamine-formaldehyde resins are most commonly used in admixture with alkyd resins. The resulting coatings are very similar to those based on melamine but they show improved resistance to alkalis.

環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a log Kow of 1.36(2) and a regression-derived equation(3), indicates that 2,4-diamino-6-phenyl-1,3,5-triazine is expected to have high mobility in soil(SRC). Volatilization of 2,4-diamino-6-phenyl-1,3,5-triazine from moist soil surfaces is not expected to occur(SRC) given an estimated Henry's Law constant of 4.1X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(4). 2,4-Diamino-6-phenyl-1,3,5-triazine is not expected to volatilize from dry soil surfaces based on an estimated vapor pressure of 1.2X10-7 mm Hg(SRC), determined from a fragment constant method(5). Biodegradation data were unavailable for 2,4-diamino-6-phenyl-1,3,5-triazine(SRC), but triazine compounds, in general, are slowly biodegraded(6).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a log Kow of 1.36(2) and a regression-derived equation(3), indicates that 2,4-diamino-6-phenyl-1,3,5-triazine is not expected to adsorb to suspended solids and sediment in water(SRC). 2,4-Diamino-6-phenyl-1,3,5-triazine is not expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 4.1X10-11 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 6.4(3,SRC), from the log Kow(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data were not found for 2,4-diamino-6-phenyl-1,3,5-triazine(SRC), but triazine compounds, in general, are slowly biodegraded(6).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2,4-diamino-6-phenyl-1,3,5-triazine, which has an estimated vapor pressure of 1.2X10-7 mm Hg at 25 °C(2,SRC), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2,4-diamino-6-phenyl-1,3,5-triazine 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 4.4 days(3,SRC).

Soil Adsorption/MobilityThe Koc of 2,4-diamino-6-phenyl-1,3,5-triazine is estimated as approximately 130(SRC), using a log Kow of 1.36(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that 2,4-diamino-6-phenyl-1,3,5-triazine is expected to have high mobility in soil(SRC). Adsorption of 2,4-diamino-6-phenyl-1,3,5-triazine, 5X10-5 M, by Na-montmorillonite at four pH levels was approximately 310 umol/g at pH 1, 460 umol/g at pH 2, 475 umol/g at pH 4, and 200 umol/g at pH 6.5maximum adsorption by the clay occurred at pH levels in the vicinity of the pKa, 3.7(4). This compound's pKa of 3.7(4), indicates it will exist predominately in the unionized form under environmental pHs(SRC). Weak bases, such as 2,4-diamino-6-phenyl-1,3,5-triazine, are more mobile in alkaline soils because cations are much more strongly adsorbed by ion exchange on organic and inorganic surfaces than the unionized bases are by organic matter(5).
Artificial Pollution Sources2,4-Diamino-6-phenyl-1,3,5-triazine's use in thermosetting resins, resin modifiersas a chemical intermediate for pesticides, pharmaceuticals, and dyestuffs(1) may result in its release to the environment through various waste streams(SRC).

Environmental BioconcentrationAn estimated BCF of 6.4 was calculated for 2,4-diamino-6-phenyl-1,3,5-triazine(SRC), using a log Kow of 1.36(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 2,4-diamino-6-phenyl-1,3,5-triazine is estimated as 4.1X10-11 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 2,4-diamino-6-phenyl-1,3,5-triazine is expected to be essentially nonvolatile from water and moist soil surfaces(2,SRC). 2,4-Diamino-6-phenyl-1,3,5-triazine is not expected to volatilize from dry soil surfaces based on an estimated vapor pressure of 1.2X10-7 mm Hg(SRC), determined from a fragment constant method(3).
