WebEthanol's miscibility with water contrasts with the immiscibility of longer-chain alcohols (five or more carbon atoms), whose water miscibility decreases sharply as the number of carbons increases. The miscibility of ethanol with alkanes is limited to alkanes up to undecane : mixtures with dodecane and higher alkanes show a miscibility gap ... WebThey dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease. After the 7-carbon heptanol, alcohols are considered immiscible.

"WebWater is a terrible solvent for nonpolar hydrocarbon molecules: they are very hydrophobic (water-hating). Next, you try a series of increasingly large alcohol compounds, starting with methanol (1 carbon) and ending with octanol (8 carbons). You find that the smaller alcohols - methanol, ethanol, and propanol - dissolve easily in water. " - Ethanol water miscibility
