Why is ethyl acetate (polar solvent) used as mobile phase for …
Ethyl acetate is a polar solvent, but it is often used in TLC. TLC''s stationary phase is usually silica gel, which is polar. I thought the whole point of TLC is to separate the polar compounds (travels less, low Rf) and nonpolar compounds (travels farther, high Rf). If the

- Why is ethyl acetate soluble in hexane? - Quora/cite>
back to your question. ethyl acetate is in fact slightly polar, but only just. its relative polarity only about 0.23. so when you use a solvent system that include ethyl acetate and another solvent which relatively more polar than ethyl acetate, meaning the value is higher that 0.23 so of course ethyl will act as a non polar solvent. for instanc
