exists in a gas phase at room temperature and 1 atm‚ but can also be obtained in solid phase (dry ice) for a general laboratory setting. In order to obtain liquid phase CO2 at room temperature and 1 atm‚ CO2 has to be pressurized and heated past the triple point‚ shown in Figure 1. 1 At temperatures above -56.6°C and pressures above 5.1 atm‚ liquid CO2 can be formed condensed and be used to extract limonene.1 The high pressure could be achieved by increasing the moles of CO2 gas
