苯酐轻组份对合成DOP质量影响的研究

Investigation of Quality Influence on Synthesized DOP by Light Component of Phthalic Anhydride

精苯酐中适量苯酐轻组份的加入 ,对邻苯二甲酸二辛酯 (DOP)产品的APHA色值和体积电阻系数没有影响 ,但加入量多少会影响DOP的纯度 ,控制轻组份掺入精苯酐的加入量可使DOP产品质量达到优级品。

No effect is acted on colour APHA and volume resistivity of dioctyl phathalate when a little of light component of phthalic anhydride was added to the fine phthalic anhydride,but the addition of light component can affect the purity of dioctyl phthalate(DOP).Controlling the addition of light component that was added to the fine phthalic anhydride,the DOP's quality can attain first-rate.
