间歇生产邻苯二甲酸二异丁酯的色度控制

Colourity Control in Intermittent Production of Diisobutyl Phathalate

邻苯二甲酸二异丁酯(即DIBP)的质量除对酯的纯度、酸度有要求之外,还应注意的是降低色度,但因生产工艺缺陷,产品带有较深颜色。依据DIBF产生颜色的原因,提出一系列工艺改进措施。

Besides of purity and acidity,lower colourity of ester is also demanded by the quality of diisobutyl phahtlate (DIBP).Becaues of technological defect,the product colourity has always been heavier. Based on the reasons of colourity in DIBP.a series of technological improving measurement are proposed.
