Does anyone have a way of pressurizing a dry ice and ethanol mixture?
I’ve used a double headed 2,000ML round bottom flask and attached a vacuum adapter to a 250ml fractional column and add dry ice to the cannabis ethanol mixture then cork it up and start a vacuum and regulate the pressure by hand using the cold trap as to not suck in any mixture into the pump. Has anyone tried this? Or is there a safer more effective way?
Does it make a difference to pressurize such a mixture or will periodically adding dry ice in an open flask with ethanol and cannabis in it work just as well?
