Stabilized pillared layered clay, process for its production

摘要

A stabilized pillared layered clay comprising a layered clay pillared by the residue of a material which has reacted with hydroxyl groups associated with the clay structure and its preparation by reacting under substantially anhydrous conditions in an organic solvent a layered clay having hydroxyl groups associated with its structure with a material capable of reacting with the hydroxyl groups and leaving a residue of the material, for example a boron trihalide, thereby pillaring the clay.
