FIELD: chemistry.
SUBSTANCE: catalytic complex of selective ethylene in 1-hexene trimerisation includes: a chromium (III) compound with a diphosphine ligand of the general formula [CrCl3((Ph2P(1,2-C6H4)P(Ph)(1,2-C6H4)CH=CH2)-(L)], where L - tetrahydrofuran or water, chloride of tris(tetrahydrofuran)chromium is applied as a chromium (III) source, a solution of methylalumoxane is applied as an activator, with the complex components being in the following molar ratio: chromium compounds: activator= 0.02-0.12%:99.88-99.98%.
EFFECT: high productivity of selective ethylene trimerisation.
