Vapour liquid equilibria for ethanol-water-ethylene glycol system

WebEthylene is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The ethylene phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the ethylene boiling point with changes in pressure. WebEthylene glycol is also called ethane 1,2 diol. This organic compound is highly toxic. It is also known as Ethane-1,2-diol or Monoethylene glycol. It has no smell and is viscous. It is colourless and has a sweet taste. It appears as a clear, colourless, liquid. It is widely used as an antifreeze and a raw material in the plastic industry. how to add two gpas together
