Publication number: 20090312567Abstract: An apparatus for use in reactions of materials with a propensity for sublimation at high temperatures has a central chamber that is immersed in a reaction vessel, attached with an air tight joint. The chamber is surrounded by a cooling jacket filled with a circulating medium, the temperature of which is adjusted below the temperature of the solution of reactants. The central chamber is immersed into the mixture and is partially filled with a liquid. This liquid is cooled by the medium circulating in the cooling jacket. The cooling ensures that the liquid filling the tube has a lower temperature than the mixture, preventing sublimation of the materials.Type: ApplicationFiled: June 11, 2008Publication date: December 17, 2009Inventor: Peter HRNCIAR
