Abstract
A method for distilling a starting material that includes a liquid Fd to be distilled, uses a gas-tight container system that is resistant to excess and/or negative pressure. The container system includes a condenser for condensing the liquid Fd, which has turned to vapor and whose temperature can be adjusted, to give the condensation product, and a vapor chamber connecting the evaporator and the condenser. The pressure and temperature in the vapor chamber are monitored and controlled so that distillation is always carried out in a range close to the saturation vapor pressure of the liquid Fd to be distilled. If the pressure is too high, it is reduced so that especially foreign gas is removed. An installation includes a container for distillation according to method.
