Web八大检索. 快速检索. 高级检索 WebPetroleum ether has a boiling point range of 35–60°C. Oxidation and polymerization of the oil that occurs during storage significantly decreased the ability of petroleum ether to extract the oil. Hexane is a more nonpolar solvent than petroleum ether; thus, it should be more effective for extracting the oil.
WebEthyl acetate is polar. Hexane is non-polar. So by using a mixture of the two you can get solutions of varying polarity. Adjusting polarity that way is easier than trying to find 10 different solvents of varying polarity. Feb 28, 2024 at 18:46 I used a silica gel for the plate... Does that make it normal phase TLC?
