METHOD FOR TREATMENT OF PROPYLENE OLIGOMER Russian patent published in 2004 - IPC

Abstract RU 2234488 C1

FIELD: organic chemistry, petroleum chemistry, chemical technology.

SUBSTANCE: invention relates to manufacturing propylene oligomers by oligomerization of propylene on phosphoric acidic catalysts and to method for treatment of propylene oligomers. Method is carried out by treatment of oligomerizate with alkali aqueous solution and the following washing out with water containing block-copolymers of propylene and ethylene oxides based on polyhydric alcohols or amines with average molecular mass 3000-10000 Da, or their mixture. The mass ratio propylene oxide : ethylene oxide in block-copolymers is maintained to be = (20-80) : (80-20) wt.-%. The proposed method allows reducing time for separation of hydrocarbon and aqueous phases and to reduce the content of neutralizing sodium phosphate salts in propylene oligomers significantly.

EFFECT: improved treatment method.
