FIELD: biochemistry.
SUBSTANCE: catalytic compositions useful for preparation of 1-butene and process for converting ethylene to 1-butene in presence of said catalyst composition are claimed. Catalytic composition for conversion of ethylene to butene-1 contains titanium-organic compound, organoaluminum compound, diester and a monoester, wherein diester is cyclic diester, linear di-ether or combination thereof, and wherein volume ratio of diester to monoester is from 1:99 to 99:1.
EFFECT: combination of diester and monoester provides higher catalytic activity than additive catalytic activity of individual ester components.
