This solvent has medium polarity, a weak hydrogen-bond acceptor, and very weak donor capability. Compared to methanol, acetonitrile has only slightly higher values for P′ and π∗, but a higher Kow. It typically acts as a stronger eluent compared to methanol. In Figure 7.6.1 are plotted...

Stronger retention is observed when the polarity of the stationary increases (hybrid particle versus silica particle) and the polarity of the mobile phase decreases (methanol versus acetonitrile). 134528948,134528949,134529159,134828125, 当固定相的极性增加(杂化颗粒与硅胶颗粒相比)和流动相的极性降低(甲醇...

PolaritySolventsThe solubility of ferrocene in n-octane, methanol, and acetonitrile has been determined as a function of temperature in the range 0–30°C using a spectrophotometric technique. From the variation in solubility with temperature, the enthalpies of solution of ferrocene in these solvents...
No enantiomeric enrichment was observed in liquid phases that are polar and capable of participating in hydrogen bonding (e.g., methanol). Introducing additives (e.g., acetic acid, triethylamine) to the liquid phase also decreased the percentage of enrichment. Finally, lowering the operating ...
