    摘要： The invention relates to a desublimator for producing particulate, solid aluminum chloride from aluminum chloride vapor, which is formed by a vessel which is closed on all sides and has vertical walls and a feed point for the aluminum chloride vapor and an offtake point for the solid aluminum chloride, wherein the walls of the vessel are formed by flat metal sheets which are welded into a rigid frame so that they can be set into vibration by being struck with a tapper.

    摘要： The present invention relates to a process for preparing largely HBr-free HCl gas and largely HBr-free aqueous HCl solution, which comprises the following steps: a) providing HBr-containing HCl gas; b) passing the HBr-containing HCl gas through aqueous HCl solution saturated with HCl; c) separating off HBr-containing aqueous HCl solution saturated with HCl; d) if desired, passing the largely HBr-free HCl gas obtained in step b) into water to obtain largely HBr-free aqueous HCl solution; with largely HBr-free aqueous HCl solution produced in step d) being able, if desired, to be recirculated to step b) of the process. The process of the present invention allows high-purity aqueous HCl solution for use in the semiconductor industry to be prepared inexpensively and on an industrial scale. However, the purified HCl gas obtained by means of steps a) to c) can also be used for any other purposes. The invention likewise provides an apparatus for carrying out the process of the present invention.
