Способ управления процессом получения олигомера, осуществляемый в смесителе в олигомеризаторе, путем регулирования подачи пиперилен-изоамиленовой фракции и раствора катализатора на основе тетрахлорида титана, измерения состава пиперилен-изоамиленовой фракции и регулирования температуры в олигомеризаторе изменением подачи теплоносителя в выносной теплообменник, отличающийся тем, что непрерывно определяют среднечисленную молекулярную массу олигомеризата и по ней судят о качестве олигопиперилена, концентрацию тетрахлорида титана в растворе и при отклонении качества олигопиперилена от заданного значения в большую сторону изменяют пропорционально подачу раствора катализатора в олигомеризатор с учетом концентрации тетрахлорида титана, а при отклонении качества олигопиперилена от заданного значения в меньшую сторону корректируют температуру в олигомеризаторе пропорционально этому отклонению, причем при выходе качества за нижний заданный предел дополнительно изменяют подачу пиперилен-изоамиленовой фракции в смеситель с учетом концентрации изоамиленов.A method of controlling the process of producing an oligomer, carried out in a mixer in an oligomer, by controlling the supply of the piperylene-isoamylene fraction and a catalyst solution based on titanium tetrachloride, measuring the composition of the piperylene-isoamylene fraction and controlling the temperature in the oligomer by changing the flow of heat carrier to the external heat exchanger, characterized in that it is continuous the number average molecular weight of the oligomerizate is determined and the quality of oligopiperylene and the concentration of titanium tetrachloride are judged by it in the solution and when the quality of oligopiperylene deviates from the set value, the flow of the catalyst solution into the oligomerizator is changed upward proportionally, taking into account the concentration of titanium tetrachloride, and if the quality of oligopiperylene deviates from the set value in a smaller direction, the temperature in the oligomerizer is proportional to this deviation, moreover, when the quality leaves the lower predetermined limit further changes the feed of the piperylene-isoamylene fraction to the mixer taking into account the concentration of isoamylene.
