| 1. | Either glyme, diglyme, nitromethane, or other suitable solvents of similar polarity may be used as the solvent component . 乙醚、乙二肟、二乙二肟、硝基甲烷或类似的适当的极性溶剂,可用作溶剂。 |
| 2. | Ether, glyme, diglyme, nitromethane, or other suitable solvents of similar polarity may be used as the solvent component . 乙醚、乙二肟、二乙二肟,硝基甲烷或类似的适当的极性溶剂,可用作溶剂。 |
| 3. | Yh - 938 b applies to middle to high polar solvent system . and yh - 938c applies to low to middle polar solvent Yh - 938b适合于中至高极性溶剂体系,如中高极性防腐漆,环氧防腐漆,工业涂料等。 |
| 4. | Introduction : the product has a very high dilatability in the polarity solvent such as water base and alcoholic group 介绍:产品在水基,醇基等极性溶剂中具有很高的膨胀性,增稠和悬浮稳定性。 |
| 5. | The eluent is changed in a regular manner starting with a nonpolar solvent and gradually replacing it by a more polar one 洗脱液以常规的顺序更换,首先用非极性溶剂,然后逐步被极性较强的所替换。 |
| 6. | Samples may be dissolved or suspended in a range of polar solvents ( but not acetone or methanol , since they are reaction products ) 试样可以溶解或者悬浮分散在极性溶剂中(但不是丙酮或者甲醇,因为它们会发生反应) 。 |
| 7. | The super - molecular structures of the solute and the solvent molecules connected by hydrogen bonding have been constructed for four kinds of polar solvents 在四种极性溶剂中,我们构造了包括氢键作用的超分子结构。 |
| 8. | Features : able to endure the erosion of oil - resisting and non - polarity solvent , heat isolation is better than the natural rubber and styrene butadiene rubber 能抗耐油和非极性溶剂的腐蚀,耐热性能比天然胶、丁苯胶好。 |
| 9. | The main properties and applications of supercritical hydrofluorocarbon are reviewed . the industrial utilization of supercritical hydrofluorocarbon as a polar solvent to replace supercritical carbon dioxide is also discussed 摘要介绍了超临界氟代烃流体的主要特性及应用,探讨了其作为一种极性溶剂取代超临界二氧化碳溶剂的应用前景。 |
| 10. | Nonpolar solvent with little dielectric constant has good effect to the rate of the reaction , while larger polar solvent without h ( superscript + ) also can increase the rate of the reaction 可以知道对甲醇羰基化这一反应,在极性溶剂中,极性较大且为非质子型的溶济能显著提高反应的速率;非极性溶剂中,介电常数较小的溶剂能增加反应速率。 |
