Abstract: Disclosed is a continuous process for preparing triallyl isocyanurate (TAIC), comprising rearrangement of triallyl cyanurate (TAC) in the presence of a Cu salt at a temperature of at least 90 degrees Celsius, wherein TAC and a Cu2+ salt are introduced continuously in an amount of 0.01 to 1 per cent by weight of Cu2+, based on TAC, separately from one another or in the form of a mixture comprising these components, into a TAIC-containing reaction mixture which has been formed at at least by 90 degrees Celsius by rearrangement of TAC in the presence of a Cu2+ salt and has not been cooled below 90 degrees Celsius thereafter, the rearrangement is performed under these conditions while maintaining a temperature in the range of 90 to 160 degrees Celsius and an amount of reaction mixture corresponding to the addition is discharged continuously and TAIC is isolated therefrom.

Abstract: The invention is directed to an improved, reliably performable process for preparing triallyl isocyanurate (TAIC) by Cu-catalysed rearrangement of triallyl cyanurate (TAC) at at least 90°C. According to the invention, TAC and, if required, also a Cu 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.
