The cell was equipped with viewing windows, with gauges for pressure measurement and temperature measurement using two thermocouples for the liquid and gas phases. The low temperatures were achieved by immersing the copper extension of the cell in liquid nitrogen provided with a pressure controller and utilizing an intermediate electric heater. The cell itself was surrounded by a steel vacuum jacket for insulation. An electromagnetic plunger-type stirrer was used. In most of the experiments only the liquid phase was analyzed and that by GC.
