      主要用于脂肪、油脂、石蜡等的碘值测定。

     操作时要洗净、烘干,称取试样,置于碘价烧瓶中,把溶剂及碘液(溴化钾溶液)仔细的加入瓶内,盖紧瓶塞摇匀,然后在宽口及玻璃塞处,滴入数滴碘化钾溶液。在20~30度的温度情况下放置30分钟(放在暗处),要不断地摇动,使试样的被测物质(不饱和物)与碘充分加成。试验结束时,打开活塞,使瓶口部分的碘化钾溶液流入瓶内摇匀(均无损失),再用新配制的10%碘化钾溶液10mL和蒸馏水50mL,把瓶塞和瓶颈上的液体冲入瓶内摇匀。用0.1mol/L硫代硫酸钠溶液迅速滴定并充分摇动,使混合液由深色变为黄色,加入1mL 1%的淀粉指示剂,继续滴定将至终点时,用力振荡,直到溶液至蓝色消失为止。同时作一个空白试验,以消耗硫代硫酸钠的毫升数,减去空白试样所消耗的毫升数,再算出试样消耗碘的克数,这个克数就是试品的碘价值。

     定碘烧瓶是一个上口成喇叭形状,并具有玻璃磨砂口、塞的锥形烧瓶。上口成喇叭形,是在实验时可倒入水或碘化钾溶液进行封口;具塞是防止瓶内物质挥发外溢,使实验更为准确。
