Aromatic solvent evaporation of volatile is relatively low in calories, fast and dissolubility, while the larger class of toxic solvents; solvents volatile dissolubility good, fast, low cost, but a large cretonne; alcohols in dissolubility, not volatile speed and above two categories, but non-toxic, tasteless, pollution-free.

芳香类溶剂蒸发热量比较低、挥发速度快、溶解性能高，但该类溶剂毒性较大；酯类溶剂溶解性能好、挥发速度快、成本低，但气味比较大；醇类溶剂在溶解性能、挥发速度上都不及以上两类，但是无毒、无味，没有污染。

The system at higher temperature becomes thermodynamically more stable, and raises the diffusion exchange rate of solvent and nonsolvent at the interface according to the diffusion kinetics. For the PANCMA/DMSO/ system, with the addition of DMSO to nonsolvent, the cloud point curves shifts to the polymer-nonsolvent axis, and the homogeneous phase region is broadened, system becomes thermodynamically more stable and needs more nonsolvent mixture to induce liquid-liquid phase separation.

通过浊点滴定，结合LCP半经验关系，可以得到制膜体系PANCMA/溶剂/非溶剂的三元相图浊点线，考察其相分离过程中的热力学性质，同时考察了溶剂和非溶剂双向扩散传质动力学，从体系热力学和动力学性质出发为PANCMA中空纤维膜的制备以及解释最终的膜结构和性能提供理论依据。

On the other hand, in accordance with the principle of solvation, its high polymer dissolution and swelling and phosphatization for solvent, that is, they say polymers and solvent, solvent molecules on the polymer molecules of the forces generated from each other.

另一方面，在溶剂化的原则下，其高聚合物的溶胀和溶解与溶剂化作用有关，即常说的高分子聚合物和溶剂接触时，溶剂分子对高聚物分子相互产生的作用力。

During the reaction,the bromide component has been converted to catalytically inactive benzylic bromide.In pure acetic acid medium,the "catalyst failure" occurs owing to the formation of benzylic bromide while in acetic acid-water medium,the solvolysis of benzylic bromide by water maintains the catalytic activity to some extent.

反应过程中溴组分会转变为无活性的苄溴，在纯醋酸溶剂中，催化剂会因苄溴的形成而发生催化剂失活现象；在醋酸-水混合溶剂中，由于水对苄溴的溶剂化作用会使苄溴还原为溴离子，一定程度上保持了催化剂活性；并且在一定范围内，含水量的提高有益于生成醛选择性的提高，研究表明，将混合溶剂的初始含水量控制在5-10wt。

The research on bound rubber and reinforcing effect of mineral filler showed that there are four kind of interactions between filler and rubber matrix in uncured mix The unbounded rubber on the surface of filler will solve in organic solvent The rubber bounded by stronger physical or chemical interaction with filler will dissolve in organic solvent The bound rubber on the surface of filler by different extent acid-base interactions will solve in basic organic solvent The bound rubber on the surface of filler by chemical action (no acid-base type) will dissolve in basic organic solvent

结合橡胶和增强作用的研究表明，在混炼胶中，硅橡胶与矿物填料的作用形式有四种。没有联结在矿物表面的非结合橡胶和仅靠物理吸附联结在填料表面的硅橡胶将溶解于有机溶剂；与填料有较强相互作用的硅橡胶不溶于有机溶剂；通过不同层次的酸碱作用联接在矿物表面的硅橡胶将溶解于碱性有机溶剂；与填料有牢固化学结合的硅橡胶不溶于碱性有机溶剂。

The B and Q bands, the characteristic bands of the two metalloporphyrins, undergo bathochromic shift in some of the Lewis basic solvents. The spectral changes are thought to be due to the axial coordination of these solvents with vanadium in VOTPP and nickel in NiTPP. After axia...

结果表明，金属卟啉可以和一些Lewis碱性溶剂发生轴向配位作用，其特征紫外可见吸收峰发生红移；轴向配位作用与卟啉中心金属离子的外层d轨道电子数、碱性溶剂的供电子能力及其空间构造有关，VOTPP比NiTPP更容易和Lewis碱性溶剂发生轴向配位作用；碱性强、空间阻碍小的Lewis碱性溶剂易于与金属卟啉发生轴向配位作用。
