Separation and recovery of cerium compound |
| abstract |
PURPOSE: To recover a Ce compound in high yield by adding an aqueous solution of an alkali to a mixture containing a naphthalenecarboxylic acid and a Ce compound and dissolving the naphthalenecarboxylic acid. n CONSTITUTION: A mixture containing a naphthalenecarboxylic acid (e.g. naphthoic acid, naphthalenedicarboxylic acid or naphthalenetricarboxylic acid) and a Ce compound is added with an aqueous solution of an alkali selected from NaOH, Na 2 CO 3 , K 2 CO 3 . NaHCO 3 and KHCO 3 and reacted for 1-3hr to dissolve the naphthalenecarboxylic acid in the form of an alkali metal salt. The solution is separated into solid and liquid and the insoluble Ce compound is separated and recovered. n COPYRIGHT: (C)1990,JPO&Japio |
