Patent ID: 8198431

Claim:
A 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° C., wherein TAC and a Cu 2+ salt are introduced continuously in an amount of 0.01 to 1% by weight of Cu 2+ , 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 90° C. by rearrangement of TAC in the presence of a Cu 2+ salt and has not been cooled below 90° C. thereafter, the rearrangement is performed under these conditions while maintaining a temperature in the range of 90 to 160° C. and an amount of reaction mixture corresponding to the addition is discharged continuously and TAIC is isolated therefrom.
