METHOD FOR THE SELECTIVE INDUSTRIAL PRODUCTION OF 1,5,9 CYCLODODECATRIENE

摘要

The invention relates to a method for the trimerisation of butadiene to form cyclododecatriene by continuously feeding butadiene into a main reactor volume, for producing a reaction mixture in the main reactor volume which comprises non-converted butadiene and cyclododecatriene, and for providing isothermic conditions in the main reactor volume by tempering the reaction mixture. Said method also continuously the following steps: the reaction mixture produced in the main reactor volume is continuously guided into a post-reactor volume and converts at least one part of the non-converted butadiene in the post-reactor volume into cyclododecatriene. Said reaction mixture provided in the post reactor volume is essentially in adiabatic equilibrium. The invention also relates to a reactor arrangement for carrying out said method comprising a main reactor and a secondary reactor. Subsequently, in accordance with the inventive method, the temperature difference is detected for determining the butadiene concentration in the main reactor and for monitoring the operation or the method.
