二异丙基醚

进料丙烯／水比降低，二异丙基醚选择性下降。

As propylene / water ratio decreases , DIPE selectivity decrease .

二异丙基醚辛烷值高、含氧量高、雷德蒸气压低，很可能成为甲基叔丁基醚的一种理想替代物。

Diisopropyl ether has higher octane number , higher amount of oxygen and lower Reid pressure , so it is likely to become an ideal substitute of the methyl tert-butyl ether .

产物异丙醇和二异丙基醚间存在平衡分布。

There is an equilibrium distribution relationship between DIPE and isopropanol .

结论是：等温下用二异丙基醚萃取水中对苯二酚并不很有效。

The results show that it is inefficient to use diisopropyl ether as extractant to extract hydroquinone from water isothermally .

在50℃、46℃和常压下实验测定了对苯二酚在二异丙基醚和苯酚中的饱和溶解度。

The saturated solubility of ternary system of diisopropyl ether-phenol-hydroquinone has been measured at 50 ℃ and 46 ℃ under normal pressure .

二异丙基醚萃取水中对苯二酚的饱和分配系数仅为0.7~1.3，远小于二异丙基醚萃取水中苯酚的分配系数。

The distributive coefficients are about 0.7 ~ 1.3 for the extraction of hydroquinone from water with diisopropyl ether , which are much less than those for the extraction of phenol from water with the same extractant .
