How does increasing the polarity of the solvent system affect the results

How does increasing the polarity of the solvent system affect the results of a TLC? In general, the adsorptivity of compounds increases with increased polarity (i.e. the more polar the compound then the stronger it binds to the adsorbent). The eluting power of solvents increases with polarity. The stronger a compound is bound to the []

Green solvents and technologies for oil extraction from oilseeds

2021/1/23Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents.
