生产方法 |
从煤焦或温沥青蒸馏中提取。将沥青馏出物蒸馏切取的屈馏分,与苯和三甲苯的混合溶剂以1:0.5或1:1的比例混合,在110-130℃温度下萃取3h,萃取时要进行搅拌。经过约20h的沉淀后,用真空吸滤分取结晶,干燥得工业。以1:1洗油重结晶两次,得到的粗品在2%-5%的顺丁烯二酸酐存在下,溶于净洗油中,加热到125-135℃。然后在20-25℃下进行结晶,用离心机分离,用苯洗涤、干燥,得纯度为85%-90%的产品。
|
用途 |
用于非磁性金属表面探伤用荧光剂、化学仪器紫外线过滤剂、光敏剂及照像感光剂,用于染料生产,代替洗油作农药敌稗的溶剂和增效剂。

Occurs in coal tar. Is formed during distillation of coal, in very small amount during distillation or pyrolysis of many fats and oils. Chrysene is one of the basic polycyclic aromatic hydrocarbon (PA H) which is toxic environmental pollutant and consistently exposed to sunlight. However, little information is available on its photogenotoxicity. The objective of the present study was to analyze th e effects of Chrysene, under environmental intensity of UVB (0.6 mW/cm2) in human skin epidermal cell line (HaCaT). |
