A static method was used to measure the critical temperature, critical pressure, and critical volume on three compounds : ethyl thioacetate, methoxybenzene, and 2-methoxyethanol. A flow method was used to measure the critical temperature and critical pressure on eleven compounds : acrylonitrile, 1,4-butanediol, 2-(2-butoxyethoxy)ethyl acetate, gamma-butyrolactone, cyclohexanol, 1,2-ethanediamine, 2-(2-ethoxyethoxy)ethanol, 2-(2-ethoxyethoxy)ethyl acetate, 1-methoxy-2-propanol, 2-(2-methoxyethoxy)ethanol, and 2-nonanone.
