Abstract
Nuovo processo per la preparazione di 2, 2, 6, 6-tetrametil-4-piperidilossi-1, 3, 5-triazine basato sulla reazione di cloruro di cianurile con alcanoli C1-C4 o con C1-C4 alcossidi di sodio o potassio e successiva reazione con 2, 2, 6, 6-tetrametil-4-piperidinoli in presenza di un catalizzatore di transesterificazione. Le diverse reazioni possono essere effettuate nello stesso reattore, senza isolamento dei composti intermedi.
