HIGH-POROSITY CELLULAR CATALYST HAVING ACIDIC PROPERTIES TO MODIFY COLOPHONY Russian patent published in 2006 - IPC B01J23/44 B01J21/04 B01J21/06 C09F1/04

Abstract RU 2279913 C1

FIELD: organic synthesis catalysts.

SUBSTANCE: catalyst for modifying colophony contains, as carrier, high-porosity cellular α-alumina-based block material and, as active catalyst fraction, sulfated group IV metal oxide and metallic palladium.

EFFECT: increased modification rate due to developed catalyst surface and eliminated disintegration and carry-over of catalyst.
