查询词典 solvent

During the preparation, when the water was used as solvent, the sodium stearate is dispersed by the acid-base neutralization reaction between sodium silicate and stearic acid in water solution, and is encapsuled by the reverse reaction; while when the alcohol/water mixed solution was used, the dispersion and encapsulation of the stearic acid is accomplished via esterification and hydrolysis in alcohol/water solvent.

If a specially appionted solvent is used in esterifying reaction, APG to solvent will be 1 to 0.6-0.7. And then, the final yield is more than 70％,and its properties indicate that it is a better anion surfactant. Such can pave the new way for the application of APG.

若酯化反应选一合适的溶剂，则APG：溶剂为1∶0.6-0.7时，阴离子活性物含量可达70％以上，测试其性能，表明为比较优良的阴离子表面活性剂，这样就为APG的应用开辟了新途径。

It is found that compared with the untreated glass fiber reinforced unsaturated polyester, the fluoridized FRP"s property of anti-water and anti infirm-acid has enhanced, while theproperty of anti- strong acid, anti-strong alkali and anti-organic solvent hasn"t changed much.The property of anti-acid and anti-alkali of the glass fiber reinforced epoxy resin fluoridizedby 3-(1H, 1H, 5H-Octafluoropentyloxy)-1, 2-Propenoxide has a corresponding increase, but theproperty of anti-organic solvent hasnt changed much.

研究发现，经G-02、G-04处理后的聚酯玻璃钢的与未处理的聚酯玻璃钢相比，其耐水性增强，耐弱酸性也有所增强，但耐强酸性、耐碱性、耐有机溶剂的腐蚀性变化不大；而经环氧丙基八氟戊醚处理后的环氧玻璃钢其耐酸耐碱性都有相应的增强，但是其耐有机溶剂的腐蚀性无太大变化。

Water borne paints like acrylic lacquers dry by evaporation of the solvent - be it water based solvent.
