| titleOfInvention | The preparation method of 4-[(4,6-bis-pungent sulfenyl-1,3,5-triazine-2-base) amino]-2,6 di t butyl phenol |
| abstract | A kind of 4 [(4, 6 two pungent sulfenyls 1, 3, 5 triazine 2 bases) amino] 2, the preparation method of 6 DI-tert-butylphenol compounds, it is prepared according to the following steps: solvent is added in reaction vessel by (1), it is cooled to less than 5 DEG C, add Cyanuric Chloride and n-octyl mercaptan, wherein Cyanuric Chloride is 1:1.95 ~ 2.05 with the mol ratio of n-octyl mercaptan, after charging, dropping sodium hydroxide solution, after dropping, at 10 ~ 10 DEG C of response time 1 ~ 5h, then it is 2 ~ 10h 10 ~ 60 DEG C of response time, obtain 2, 4 two spicy thioalcohol base 6 chlorine 1, 3, 5 triaizine compounds, heat up；(2) in a nitrogen atmosphere, 2,6 di-t-butyl para-aminophenol and acid binding agents are added；Then heat up and react 2 ~ 4 hours at reflux；After completion of the reaction, after removing solvent and residual water, add precipitation agent, cooling, filter, be dried, obtain product.Product of the present invention does not has mercaptan taste, and quality better, purity are high；Described method technique is simple, and the response time is short, and yield is high, and low cost is suitable to industrialized production. |
