PROPYLENE TRIMER AND TETRAMER PRODUCTION PROCESS Russian patent published in 2003 - IPC

Abstract RU 2200725 C1

FIELD: petrochemical processes. SUBSTANCE: propylene is subjected to oligomerization in presence of catalyst containing 0.5-1.3 wt.% nickel immobilized on polymer carrier and organoaluminum compound as activator. Oligomerization product is divided into two streams, one of them being recycled into oligomerization process and the other rectified to give oligomers fraction, which is also returned into oligomerization stage. EFFECT: improved workability and reduced expenses. 2 tbl, 12 ex
