| Abstract: | Used saturated solution of magnesium chloride containing 0.1 mol/L hydrochloric acid as the addition reaction reagent,the determination of epoxy group was investigated in this paper.These factors of reaction time and reaction temperature on the analysis accuracy were also explored.The results indicated that:the relative error of the determination maintained at 60 ℃ temperature for 45min was below 1%,the results conformed with the ion chromatographic(IC)method.This method to epoxy determination was convenient for the determination of epoxysuccinic acid(salt)in industrial production. |
| Keywords: | epoxysuccinic acid(salt) epoxy group saturated solution of magnesium chloride relative error |
