ZIRCONIUM PHOSPHATE COMPOUNDS AND THEIR USE TO TREAT EDIBLE OILS

摘要

Zirconium phosphate-type intercalates having a reduced intercalant density may be prepared by producing a zirconium phosphate type intercalate in which the intercalant species are bonded to the matrix via differentially breakable bonds and treating the intercalate to break the more easily breakable bonds and to remove a proportion of the intercalant. The intercalant may be bonded via a mixture of phosphate and phosphonate or phosphite bonds and that bonded via the phosphate bonds may be removed by preferential hydrolysis of those bonds. The intercalate so produced may be used as an adsorbent to remove impurities from edible oils.
