ABSTRACT:
Apparatus for the chemical synthesis of an evaporant and a liquid has a cryogenic pumping device between the evaporant source and the reaction region and a pump causes the liquid to be continuously recirculated until the reaction is completed, the pressure in the evaporation region being maintained substantially lower than that in the reaction region by differential pumping.
