| titleOfInvention | Catalytic system of ethylene in 1-hexene trimerisation |
| abstract | FIELD: chemistry. n SUBSTANCE: catalytic system of ethylene in 1-hexene trimerisation includes a chromium (III) complex with a diphosphoric ligand of the general formula [CrCl 3 [(Ph 2 P(1,2-C 6 H 4 )P(Ph)(1,2-C 6 H 4 )(R)](THF)], where R is a hydrocarbon radical or a heteroatom-containing hydrocarbon group, which is in a phenyl substituent in the ortho-position relative to one of the phosphorus atoms. A source of chromium (III) is represented by tris(tetrahydrofuran)chromium chloride, and an activator, representing a mixture of solutions of trimethylaluminium and partially hydrolysed trimethylaluminium in toluene or methylcyclohexane. The molar ratio of the catalytic system components [Cr] : partially hydrolysed trimethylaluminium : trimethylaluminium constitutes 0.03-1.09%:6.95-31.92%:67.39-92.81%. n EFFECT: obtaining high selectivity by 1-hexene with the simultaneous reduction of the quantity of ethylene polymerisation byproducts in the process of trimerisation. n 2 cl, 2 tbl, 19 ex |
