屈 用途與合成方法
化學性質 白色或帶銀灰色、黃綠色鱗片狀或平斜方八面結晶體,在苯中結成無色斜方片晶,在紫外線下有紫色熒光。可燃。有毒。真空中易升華。熔點255℃,沸點440.7℃,相對密度1.274。微溶于醇、醚、二硫化碳和冰醋酸,在25℃時1g能溶于1300ml無水乙醇、480ml甲苯,在100℃時在甲苯中約溶解5%,略溶于沸苯,不溶于水。
用途 用于非磁性金屬表面探傷用熒光劑、化學儀器紫外線過濾劑、光敏劑及照像感光劑,用于染料生產,代替洗油作農藥敵稗的溶劑和增效劑。
用途 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. 聽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).
生產方法 從煤焦或溫瀝青蒸餾中提取。將瀝青餾出物蒸餾切取的屈餾分,與苯和三甲苯的混合溶劑以1:0.5或1:1的比例混合,在110-130℃溫度下萃取3h,萃取時要進行攪拌。經過約20h的沉淀后,用真空吸濾分取結晶,干燥得工業。以1:1洗油重結晶兩次,得到的粗品在2%-5%的順丁烯二酸酐存在下,溶于凈洗油中,加熱到125-135℃。然后在20-25℃下進行結晶,用離心機分離,用苯洗滌、干燥,得純度為85%-90%的產品。
