The invention is directed to an improved, reliably performable process for preparing triallyl isocyanurate (TAIC) by Cu
2+
-catalysed rearrangement of triallyl cyanurate (TAC) at least 90° C. According to the invention, TAC and, if required, also a Cu
2+
catalyst and solvent are fed continuously to a start reaction mixture after onset of the initially inhibited isomerization reaction, the isomerization is performed at from 90 to 160° C. and an amount of reaction mixture equivalent to the amount of reactant is drawn off continuously and sent to the workup. Preference is given to effecting the isomerization in TAIC as the reaction medium.
该发明涉及一种改进的、可靠的制备
三烯基异
氰酸三酯(TAIC)的过程,通过在至少90°C时Cu2+催化的
三烯基
氰酸三酯(TAC)重排。根据该发明,在最初受抑制的异构化反应开始后,将TAC以及必要时还有Cu2+催化剂和溶剂连续加入到起始反应混合物中,异构化在90至160°C进行,并连续取出相当于反应物量的反应混合物并送至后续处理。优选在TAIC作为反应介质中进行异构化。
