WebThere are higher order azeotropes – ternary and quaternary – but they are less common and more dificult to characterize. Perhaps the most famous is the water/ethanol/ benzene azeotrope (bp 64.9°), which has a lower boiling point than even the water/ethanol azeotrope (78.2°C). So one trick to making 100% ethanol (anhydrous or absolute Cyclopentyl methyl ether (CPME), also known as methoxycyclopentane, is hydrophobic ether solvent.
