水封碘量瓶口对造粒间苯二酚中间苯二酚含量测定的影响

摘要

Pelletizing resorcinol content was determined by indirect iodimetry, through water sealing plug of io-dine flask or not, the results showed that water sealing plug of iodine flask caused resorcinol content low. So not to seal the plug of iodine flask after adding bromine solution, but to cover the flask and keep it in the dark place.%在间接碘量法测定造粒间苯二酚中间苯二酚含量试验中,通过在碘量瓶口加水封与不加水封的对比试验及分析,得出水封碘量瓶口可造成间苯二酚测定结果偏低的结论,所以在间苯二酚含量测定试验时,加溴溶液后,不要水封碘量瓶口,直接盖好塞子于暗处放置即可.
