product was fractionally distilled a t atmospheric pressure. The first fraction boiling a t 81-83' consisted of benzene. The product boiling at 130-132" (5.62 8.) was shown to be chlorobenzene. The semisolid residue from the steam distillation was extracted with benzene, washed neutral and was dried by distillation with benzene. It weighed 28.07 g. The dry residue was sublimed a t 160-200' (2 mm.)
产物在常压下分馏。沸点为 81-83' 的第一馏分由苯组成。沸点为 130-132" (5.62 8.) 的产物显示为
氯苯。
水蒸气蒸馏的半固体残余物用苯萃取,洗中性并用苯蒸馏干燥。重 28.07 g。干残余物为在 160-200'(2 毫米)升华。升华物溶解在最少量的 Skellysolve C 中,吸附在氧化铝上。在紫外光下可见蓝色荧光带,用相同的溶剂洗脱。得到 12.70 g.
蒽,mp 212-214'。用苯洗脱的棕色条带含有 7.40 g 三
苯甲醇,mp 160-162'(来自 Skellysolve B)。以相同方式处理的异构甲氧基、
氯和羟基
苯甲醛,生成
苯酚和
氯苯为挥发性产物。非挥发性物质由
蒽、三
苯甲醇和焦油组成。具有相同构型的醛的挥发性和非挥发性物质的产率依次为
