| Abstract: | Direct determination for free propylene glycol content in propylene glycol ester was put forward.A series of samples was respectively assayed with both direct determination and extraction determination.The result showed that direct determination takes less time and easier to handle with no significant diversity in comparison with extraction determination.The recovery rate was 95.7?.0%,and relative standard deviation(RSD)was 0.23%0.60%. |
