CAS号: 65996-93-2 英文名称: Coal tar 英文同义词: COAL TAR;4-tridecenyl acetate 中文名称: 煤焦油 中文同义词: 沥青,煤焦油,高温 分子式: 分子量: 0 Mol file 熔点 : 30-180 °C 沸点 : >250 °C 密度 : >1 g/cm3 溶解度 : Slightly soluble in water; partly soluble in ethanol , in ether and in volatile oils. 形态: As stated by ACGIH: The pitch of coal tar is the black or dark brown amorphous residue that remains after the redistillation process. The volatiles contain a large quantity of lower molecular weight polycyclic hydrocarbons. As these hydrocarbons (naphthalene, fluorene, anthracene, acridine, phenanthrene) sublime into the air there is an increase of benzo(a)pyrene (BaP or 3,4-benzpyrene) and other higher weight polycyclic hydrocarbons in the tar and in the fumes. Polycyclic hydrocarbons, known to be carcinogenic, are of this large molecular type. (IARC)致癌物分类: 1 (Vol. 35, Sup 7, 100F) 2012 EPA化学物质信息: High-temperature coal tar pitch (65996-93-2)
