Abstract 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).Resin and rubber used as the solvent, to dissolve polystyrene, ABS, PMMA, polyvinyl butyral, polysulfone, polyether chloride, styrene butadiene rubber, solvent-based adhesive preparationKey words:Carbon tetrachloride, chloroform, hydrogen, methane

MeABP(mean average boiling point) 中平均沸点concarbon (Conradson Carbon) Conradson carbon residue 康拉特逊残碳值\康氏残碳量参考：在线石油词典Heaviness可以指重量，容量的大小，也可以指沸点的高低，我认为。feeds of a specific heaviness 的feeds是指进料：给机器或炉子供给的原料或进料量a specific heaviness 指特定的重量或容量在FCC上加工的是feeds而不是heavinessMeABP(mean average boiling point)就是指中平均沸点。
