Using the ionic liquids, the synthesis process became greener and simpler because of easy product separation and catalyst recycling and unnecessary use of volatile and harmful organic solvents.

使用离子液体使得合成过程变得更加绿色和简单，因为产品易分离，催化剂可以循环利用，而且不必使用挥发性有害的有机溶剂。

Like 84-1lmi adhesive, this product also exhibits low levels of extractable ionic impurities.

同84 - 1lmi胶一样，本产品也表现出了杂质离子含量低的特性。

That is because, as in the case of the Diels-Alder reaction, it is usually possible to design an ionic solvent that dissolves the reactants easily but is reluctant to give house room to the resultant product.
