对氯苯酚与多聚甲醛在氢氧化钠存在下70℃反应3小时,即得粗产率98%的4-氯-2,6-二(羟甲基)苯酚(试铁酚).实验表明铁(Ⅲ)-试铁酚在pH6.4时,可生成稳定的橙红色络合物,吸收峰在480nm处,摩尔吸收系数为6.4×103可用于铁(Ⅲ)的定量测定.本法的优点是选择性较高,测定范围广,方法简便、迅速,可用于土壤、岩石等样品中铁的直接测定.本法与其它方法测得的结果一致.

In this paper a modified prooednre for the synthesis of the reagent Ferriphene, 4-chloro-2, 6-di-(hydrozymeihyl) phenol, was desorided.Paraformaldehyde react with p-ohlorophenol at 60-70℃ for 2-3 hr using solid NaOH as oatalyst.The yield of the orude prodnot was 98%.
