The light stabilizer intermediate 2-chloro-4,6-bis(n-butyl-2,2,6,6-tetramethyl-4-piperidinyl)-1,3,5- triazine was synthesized by single factor method with cyanuric chloride, n-butyl-2,2,6,6-tetra- me-thyl-4-piperidinyl and sodium hydroxide as raw materials, xylene as solvent and tetrabutyl ammo-nium bromide as catalyst. The results showed that the optimum reaction conditions were as follows: the reaction temperature in the first stage was 5?C~8?C, the reaction time was 2 h, the temperature in the second stage was raised to 60?C, the reaction time was 5 h, the ratio of raw material n(cyanuric chloride):n(n-butyl-2,2,6,6-tetramethyl-4-piperidine):n(sodium hydroxide) = 1:2.15:2.15, the amount of catalyst tetrabutyl ammonium bromide was 0.20 g (relative to 0.05 mol cyanuric chloride), the yield of the product was 95.61%. %K 光稳定剂,三聚氯氰,N-丁基-2 %K 2 %K 6 %K 6-四甲基-4-哌啶胺,2-氯-4 %K 6-二(N-丁基-2 %K 2 %K 6 %K 6-四甲基-4-哌啶胺基)-1 %K 3 %K 5-三嗪
