摘 要: 为得到满足麦面化学实验研究规格的十二烷基硫酸钠(以下简称SDS),用水结晶、泡沫分离、乙醇三次重结晶、乙醚抽提对市售的一种C.P.级试剂进行纯化处理。就所得结果对各种纯化方法的特点进行比较、分析和讨论,据此提出了一种纯化市售C.P.级试剂的方案,并用于另一种市售C.P.级试剂的纯化,获得满意的结果。 In order to attain sodium dodecyl sulphate that meet the need of experimental re-se arch in surface chemistry, crystallization from water, Separation with foam, recrystallization three times from echanol, extraction with ether had been made to purify it. After the results were compared analysed and discussed, a programme that purify C. P, reagent had been raised. This programme had been used for purifying another C. P. reagent. The result is satisfactory.
