苯酚甘油系临床上常用的一种外用制剂,苯酚含量为1%(g/g)。其测定方法一般都采用碘量法或溴量法进行,方法不够简便、精确。因苯酚在碱性溶液中与4-氨基安替匹林作用,经铁氰化钾氧化可生成红色衍生物,其色泽与苯酚含量成正比。因而我们试用比色法对苯 Phenol glycerol is clinically used as a topical formulation with a phenol content of 1% (g / g). The determination methods are generally used iodine method or bromine method, the method is not simple and accurate. Phenol in alkaline solution with 4-amino-aspirin role, the oxidation of potassium ferricyanide can generate red derivatives, the color and the phenol content is proportional to. So we try colorimetric benzene
