Title: Dehydrating method for hydrogen fluoride
Inventor: JIYOZEFU II ISUTAA
IPC: C01B23/00
Filed: 1988-11-02
Abstract: PURPOSE: To effectively dehydrate hydrogen fluoride by allowing hydrogen fluoride containing water to contact with a specific metallic halide to allow the contained water to react with the metallic halide to remove.  
     CONSTITUTION: Hydrogen fluoride containing water is allowed to contact with the metallic halide selected from TiCl 4 , HfCl 4 , ZrCl 4  and the combination to cause a reaction expressed by a formula between water and the metallic halide to produce a metal oxide and a hydrogen halide and a hydrogen fluoride anhydride. Next, hydrogen fluoride anhydride is obtained by separating the reaction product into each component. A high purity zirconium fluoride containing no oxygen in the crystal structure is produced by using the resultant hydrogen fluoride for the production of zirconium fluoride by CVP method.
