| titleOfInvention | A kind of method preparing 3-formyl radical-10-alkyl thiodiphenylamine |
| abstract | The invention provides a kind of method preparing 3-formyl radical-10-alkyl thiodiphenylamine, first, phosphorus oxychloride is dissolved in DMF at normal temperatures, and stir, then, in the mixed solution obtained, add N-alkyl thiodiphenylamine, and be warming up to 80 DEG C of reactions, after having reacted, obtain reaction mixture; Finally, poured into by reaction mixture in frozen water, regulate pH to separate out to solid, then filter out solid by NaOH solution, solid, through washing, dry also recrystallization, namely obtains 3-formyl radical-10-alkyl thiodiphenylamine.The present invention take phosphorus oxychloride as catalyzer, DMF and N-alkyl thiodiphenylamine is that reaction raw materials prepares 3-formyl radical-10-alkyl thiodiphenylamine, has higher productive rate, and raw material addition sequence is reasonable, makes the reaction times short, easy and simple to handle, and reaction is without the need to solvent, therefore temperature of reaction is lower; Aftertreatment simultaneously only need regulate pH to obtain solid, and then can obtain sterling through recrystallization, therefore post-processing operation is simple. |
