m-톨루이딘 C화학적 특성, 용도, 생산
화학적 성질
Colorless liquid. Slightly soluble in water; soluble in alcohol or ether. Combustible.용도
m-Toluidine is an intermediate in the manu facture of dyes and other chemicals.일반 설명
A clear colorless liquid. Flash point below 200°F. Vapors heavier than air. Toxic by inhalation, ingestion, and skin absorption in high concentrations or under prolonged exposures. Used in the manufacture of organic chemicals. Density about 8 lb / gal.반응 프로필
m-Toluidine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. Can react vigorously with oxidizing reagents. Emits toxic fumes of oxides of nitrogen when heated to decomposition [Lewis, 3rd ed., 1993, p. 1253].건강위험
The toxicity of m-toluidine is similar to thatof o-toluidine. The exposure routes are ingestion, inhalation, and absorption through skin.The toxic effects are methemoglobinemia,anemia, and hematuria. It metabolizes to 2-amino-4-methylphenol, the major componentexcreted in urine. Inhalation of 40-ppm concentration for an hour produced severe poi soning in humans. The oral LD50 value inmice is 740 mg/kg, which is in a range com parable to its o- and p-isomers.The pure liquid is a mild to moderate skinirritant. Its irritating effect on the eyes ofrabbits was strong.
m-Toluidine did not induce any carcino genicity in test subjects. This finding is incontrast to its ortho-isomer. Nor did it produce any mutagenic activity.
화재위험
Special Hazards of Combustion Products: Toxic oxides of nitrogen and flammable vapors may form in fire.Safety Profile
Poison by ingestion and intraperitoneal routes, A skin and eye irritant. Flammable when exposed to heat or flame. Can react vigorously on contact with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits hghly toxic fumes of NOx. See also ANILINE and o-TOLUIDINE.Carcinogenicity
In an 18-month carcinogenicity diet evaluation in maleCD rats (8000 ppm for 3 months, and then 4000 ppm for additional 15 months; or 16,000 ppm for 3 months, and then 8000 for additional 15 months), and male and female CD-1 mice (16,000 ppm for 5 months, and then 4000 ppm in males and 8000 ppm in females for additional 13 months; or 32,000 ppm in both sexes for 5 months, and then 8000 ppm in males and 16,000 ppm in females for additional 13 months), there was no evidence of a significant increase of incidence of any kind of tumor in the rats, and only a significant increase in liver tumors in male mice.Purification Methods
It can be purified as for aniline. Twice-distilled, m-toluidine is converted to the hydrochloride using a slight excess of HCl, and the salt is fractionally crystallised from 25% EtOH (five times), and from distilled water (twice), rejecting, in each case, the first material that crystallised out. The amine is regenerated and distilled as for o-toluidine. The benzoyl derivative has m 125o (from EtOH).
