| Abstract: | In order to improving the purity of the industrial product,antioxidant D was purified by the methods of Recrystalize and Zone Melting.The purity was determined by High Performance Liquid Chromatography(HPLC) and Differential Scanning Calorimetry(DSC).The purity is 99.24% with Relative Standard Deviation(RSD) of 0.14%,tested from the way of HPLC.The purity tested by DSC is 99.20% with RSD of 0.05%.This purified antioxidant D reaches the same level of international product. |
