Claims17
A container of liquid mixture consisting essentially of tetrafluoroethylene and carbon dioxide under pressure.
In the process of transporting liquid tetrafluoroethylene in a container under pressure, the improvement consisting essentially of combining liquid carbon dioxide and said liquid tetrafluoroethylene, one with the other, said carbon dioxide being present in effective amount to prevent the tetrafluoroethylene vaporized from the resultant liquid mixture from exploding at temperatures up to 25.degree. C.
A liquid mixture consisting essentially of tetrafluoroethylene and carbon dioxide.
