Using the heat exchanger, while the mannered null 2,6 bis which produces the direct condition

摘要

It regards the method of producing the direct condition - olefin oligomer in the reactor to which this invention, while 2,6- bis (the aryl imino) under existing of the iron complex of the pyridine derivative, discharging heat, ethylene to oligomer converting with catalytic action, the step which from average molecular weight 50 it makes the - olefin oligomer of 350 and, at least using the vapor phase of part, as the refrigerant includes with the step which removes heat with the heat exchanger which does not contact with the liquid phase directly, includes the liquid phase and the vapor phase. This invention furthermore regards the device which executes the aforementioned method.
