摘要
研究了在冰醋酸－盐酸介质中，以ＮａＩ作还原剂，Ｆｅ３＋作催化剂，测定二叔丁基过氧化物的条件，建立了在１００℃条件下催化碘量法测定二叔丁基过氧化物的新方法。该法用于聚丙烯塑料中微量过氧化物的测定，准确、可靠、方便。回收率为９８．７％，相对标准偏差为０．６４％。
A quantitative method is studied for the determination of ditertbutul Peroxide(DTBP)inacetic acid-hydrochloric acid solution using Nal and Fe3+ for reducing asent and catalyst respeectively.A new catalytic iodometry for the determination of DTBP at 100℃ is established.It is an accurate,reliable and convenient method for the determination of DTBP in polypropylene plastics,Thepercentage of recovery is 98. 7% and the RSD is 0. 64%.
