359煤酚[剧]CRESOL[别名】甲酚;煤溜油酚;Acidum Cresylicum;Gresylic Acid。1)本品鉴别之(3):取本品,照沸点测定法的第二法(附録10页)测定,在195°—205°溜出的数量,以容量计算为80%以上。说明——本品之主要成分为煤焦油中所得煤酚之三种异构体的混合物,其蒸溜范围为195°—205℃。2)本品鉴别之(4):取本品的饱和水溶液,加三氯化(?)试液,即显易消失的紫蓝色。
359 phenolic phenol [Cine]CRESOL [alias] cresol; coal sorbent phenol; Acidum Cresylicum; Gressylic Acid. 1) Identification of this product (3): Take this product, according to the second method of boiling point determination (Appendix 10) Determination, the number of slipped out at 195 ° -205 °, with a capacity calculated as more than 80%. Explanation—The main component of this product is a mixture of the three isomers of the obtained phenol in coal tar, and its evaporative range is 195°-205°C. 2) The identification of this product (4): Take a saturated aqueous solution of this product, add trichlorinated (?) test solution, which is apparently easy to disappear purple blue.
