Structure of the phase diagram of the 2-methyl-1,3-butadiene–2-methyl-2-butene–acetonitrile–water system

Resumo

The structure of the liquid–liquid–vapor diagram of the industrially important four-component system 2-methyl-1,3-butadiene–2-methyl-2-butene–acetonitrile–water has been determined. A model of the phase equilibrium has been derived from experimental data. The evolution of the three-phase immiscibility region in the concentration simplex has been investigated.
