相似相溶原理

该体系的特点是：基于相似相溶原理，将含PEG链的膦配体与PEG进行组合使用。

The feature of PEG biphasic system was the combination PEG and phosphine ligand with PEG chains .

根据相似相溶原理，溶剂大多数为有机物，分离后对环境造成严重污染，如果用超临界水或超临界CO2做溶剂，将产生良好的效果。

According to principle of " like dissolves like " most of solvents are organics . There is too much environment pollution after the compounds are separated . If supercritical water and supercritical dioxide are used as solvent , the effect would be better .

为此，根据相似相溶原理以及PbS比重远大于硫等性质，提出一种除铜新工艺，即利用PbS代替单质硫进行除铜。

Therefore , according to the theory of PbS can be dissolved in lead and the density of PbS is much higher than S , we invented a new craftwork , it is adding PbS take the place of S in decoppering .

该法利用相似相溶原理，使废酸中的有机物转移到萃取剂中，从而使硫酸分离出来。

Sulfuric acid is separated by transferring the organics in the waste acid to the extracting agent .

然后利用相似相溶原理选择了四种有机溶剂进行剥离实验：丙酮、二甲苯、二甲基甲酰胺及乙酸乙酯。

Then , chose acetone , ethyl acetate , xylene and dimethylformamide according to solubility parameter close principle as solvents to dissolve coating finishing agents .

根据银杏叶内不同有效成分极性不一样和相似相溶原理，选用乙二醇二甲醚这一非极性溶剂提取银杏叶中非极性成分。

According to the theory that similarities can be solvable easily in each other , nonpolar ethyl diol dimethyl ether is used to extract nonpolar compounds in ginkgo biloba leaves .

根据相似相溶原理，在低温低度下，造成醇溶物质的析出而使白酒发生混浊，水硬度大时，由于温度下降，改变白酒溶液中的溶度积而使白酒产生混浊；

According to the theory of similar dissolve mutually , the isolation of certain alcohol-dissolved materials could result in precipitate in liquor under lower temperature , and any change of solubility product in liquor due to the decrease of temperature could also result in precipitate when water rigidity is high .
