    摘要: The invention relates to a method for obtaining cyclododecatriene (CDT) from a solution containing CDT and high-boiling components such as a deactivated catalyst and polymers. Said solution is supplied to a preheater and heated, and is then relaxed over a downstream pressure maintaining device, and the two-phase mixture obtained is supplied to a spiral tube evaporator where the CDT content of the liquid phase is reduced by partial evaporation and a gaseous product flow with an increased CDT concentration is derived.
