Abstract: A lab. process is described showing that by direct reaction of dry elementary Cl and dry elementary Se, and excluding even traces of humidity, 99.9% pure SeCl₄ can be obtained. SeCl₄ subjected to slow hydrolysis by introducing an inert gas (nitrogen) satd. with water vapor at room temp. gives well-defined SeOCl₂. By measuring cond. of HCl soln. which is released during hydrolysis the change of SeCl₄ into SeOCl₂ can be checked.
