FIELD: chemistry.SUBSTANCE: invention relates to a method of producing an ethylene trimerisation catalyst ligand. Described is a method of producing a ligand of a catalyst for trimerisation of ethylene to 1-hexene of general formula:where R is alkyl, Ris hydrogen and/or alkyl, involving a reaction for synthesis of 2-(alkylthio)alkylamine and 2-(alkylthio)alkylketone or alkylthioalkanal, where the alkyl in the alkylthio substitute is octyl, and the alkyl in alkylamine and alkylketone is CH, CH, in the presence of titanium tetraisopropoxide in toluene medium at temperature of 50-80°C, with subsequent addition of ethanol and tetrahydrofuran, cooling the obtained solution to 2-0°C, subsequent addition of sodium borohydride and hydrochloric acid using the following formula:wherein alkylthioalkanal is selected from a group comprising: 2-(octylthio)-2-methylpropanal, 2-(octylthio)butanal, 2-(octylthio)pentanal, 2-(octylthio)hexanal, 2-(octylthio)heptanal, 2-(octylthio)octanal, 2-(octylthio)nonanal, 2-(octylthio)decanal.EFFECT: method provides toxic and environmental safety when producing the ligands.1 tbl, 14 ex |
