Oznake: ogljikov dioksid;butanol;propanol;high-pressure phase equilibrium;carbon dioxide;2-propanol;1-butanol;2-butanol;
The ability to predict the behaviour of high-pressure mixtures of carbon dioxide and alcohol is important for industrial purposes. The equilibrium composition of three binary carbon dioxide-alcohol systems was measured at temperatures of 313.15 K and 333.15 K and at pressures of up to 100 bar for ca ...
