Chloroform also known as chloroform, Montenegro imitation, structured CHCL3, molecular weight of 119.39. Clear, colorless volatile liquid, a special sweetness. . The relative density (20 ℃ / 4 ℃) 1.489, freezing point -63.55 ℃, the boiling point 61.6 ℃, refractive index (n25D) 1.4467, solubility parameter δ = 9.4. With ether, ethanol, benzene, petroleum ether, carbon tetrachloride, benzene, carbon disulfide and oils, such as compatibility. Micro-soluble in water. Difficult to burn, but long-term exposure to combustion in the air, a flame or heat. A narcotic, toxic, is considered carcinogenic substances. In sunlight, oxygen, moisture, particularly iron and contacts, the reaction of the highly toxic phosgene. LD50909mg/kg, the maximum admissible concentration in the air 240 mg/m3 (or 0.005 percent).热心网友 时间:2022-06-26 14:02
