2-chloro-4,6-bis-naphthalen-2-yloxy-1,3,5-triazine(CDNTA) was synthesized by nucleophilic substitution reaction between cyanuric chloride and β-naphthol.The effects of the stuff molar ratio,the variety and dosage of base,the solvents,the reaction time and temperature on the yields of CDNTA were investigated.The optimized reaction conditions included that cyanuric chloride and β-naphthol were mixed at the stoichiometric ratio,sodium hydroxide was used as base(its molar ratio to cyanuric chloride was 2.1:1),mixture of acetone and water(the volume ratio was 1:1) was used as solvent,the reaction was carried out in ice water bath for 2 h,then at 40 ℃ for 7 h.Under these conditions,the yield of CDNTA could reach 96.3%.The target compound was characterized by elementary analysis,IR spectrum,1 H-NMR and MS.The solubility,thermo stability,and UV spectrum of CDNTA were investigated.
