摘要
菲在溶剂油中,随温度变化溶解度差别较大。将60.34％菲溶于在90号汽油中,80℃回流1小时,趁热过滤,将滤液冷却至室温再过滤,得到一次产物;将此产物110g完全溶于1000ml乙醇,滤去杂质,滤液蒸馏得产品,纯度84.21%收率78.15％,用GC-MS进行了定量和定性分析。
A marked difference in solubility of phenanthrene in solvent oil was observed with temperatures. Crude phenanthrene with a purity of 60.34% was dissolved in 90# petrol and refluxed for 1 hour at 80℃, then the hot solution filtered, the filtrate was cooled to room temperature, and filtered again to get the primary product. 110g of such product were dissolved in 1000ml ethanol, after the solution was being filtered, then distilled, a product with a purity of 84.21 % and a yield of 78.15% obtained. GC-MS was applied for characterizations and quantitative analysis of the product.
