Production method: 1, N-ethyl-m-toluidine reaction of acid-binding agent selected sodium hydroxide solution and sodium carbonate. N-ethyl m-toluidine and benzyl chloride ratio of 1: (0.95 ~ 1.05) (molar ratio), the reaction temperature was successively 40 ℃ and 100 ℃ temperature rise reaction to the end, and then separated by water reduction, the oil layer obtained by distillation under reduced pressure. At least 1000 kg of N-ethyl-m-toluidine can yield 1350 kg of N-ethyl-N-benzyl m-toluidine. 2, m-toluidine method Chloroethane (or ethanol) as alkylating agent N-ethyl m-toluidine, the same method with the previous method to obtain the product.
Usage: Dye intermediates. For the preparation of triaryl methane series of acid dyes, such as Acid Blue G, C.I. Acid Blue 90,91,109 and W001 Discharge Blue GN and so on.
