摘　　要：选用碘酸钾滴定法,建立了滴定分析巯基乙酸异辛酯半成品的方法。当巯基乙酸异辛酯的质量分数为60.00%～90.00 %时,采用该方法的相对标准偏差为0.05%～0.14 %。该分析方法适用于以巯基乙酸、异辛醇等为原料而合成的巯基乙酸异辛酯半成品的分析。A method for titrimetric analysis of isooctyl mercapto acetate semi finished product was established by titration of potassium iodate.When the mass fraction of isooctyl mercaptoacetate is 60.00%~90.00%,the relative standard deviation of this method is 0.05%~0.14%.The method is suitable for the analysis of semi-finished products of isooctyl mercaptoacetate synthesized from mercaptoacetic acid and isooctanol.
