概要
- 論文の詳細を見る
A new volumetric determination of ethylene oxide content in nonionics was established with sodium tetraphenylborate as a titrant using Congo red as an indicator. This method can be applied to nonionics containing more than 10 units of ethylene oxide. A linear relationship between the units of ethylene oxide and the volume of sodium tetraphenylborate was obtained that six units of ethylene oxide combined with one mole of sodium tetraphenylborate. The accuracy of this titration is about ±3%.
