Embodiment 1
[0032] Ethylene tetramerization reaction, specifically comprises the steps:
[0033] (1) In the continuous reaction device, ethylene containing water, organic solvent is methylcyclohexane, main catalyst 1 (concentration is 2.5 μ mol / mL, as formula I, wherein R 1 is methyl, R 2 is ethyl, R 3 , R 4 , R 5 and R 6 Both are phenyl, M is chromium, X is chlorine, n=3), cocatalyst triethylaluminum solution (concentration is 1mmol / mL) enters reactor respectively, and its flow rate is 80g / h, 160g / h, 3.5g / h, 2.6g / h, keeping the Al / Cr mol ratio in the reaction system is 300, keeping the residence time of the reaction material in the reactor is 30 minutes;
[0034] (2) The reaction pressure is 4MPa and the reaction temperature is 40°C, wherein, taking ethylene as the calculation basis, the mass content of water is 15ppm;
[0035] (3) Carry out gas chromatography (GC) analysis to the reaction outlet material. See Table 1 for the data.
Embodiment 2
[0037] Same as Example 1, the difference is that the mass content of water is 50ppm. See Table 1 for the data.
Embodiment 3
[0039] Same as Example 1, the difference is that the mass content of water is 150ppm. See Table 1 for the data.
