Quaternary liquid-liquid equilibrium: wateracetic acid-2-butanonecyclohexane at 25°C

Mutual solubility and tie line data at 25°C, and atmospheric pressure are presented for the quaternary system wateracetic acid-2-butanonecyclohexane. The system contains two pairs of partly miscible compounds with very different solubilities which produce a solubility surface with a large hump and tie lines which do not lie on tie line planes. The UNIQUAC equation is used to correlate the liquid-liquid equilibrium data.
