Description

ки анилин отгон ют из гор чего автоклава, а охлажденную реакционную массу промывают водой и сушат. Получают 27,9 г технического дифениламина с т. пл. 48-49°С. Выход технического продукта 99%.Aniline acids are distilled off from a hot autoclave, and the cooled reaction mass is washed with water and dried. Get 27.9 g of technical diphenylamine with so pl. 48-49 ° C. The yield of technical product is 99%.

Пример 4. 30 г (0,165 мол ) натриевой соли бензолсульфокислоты, 56 г (0,33 мол ) 2-нафтиламида натри  и 36 г (0,25 мол ) 2нафтиламина нагревают при 400°С в течение 20 ч. Реакционную массу обрабатывают аналогично примеру 3. Получают 13,8 г N-фенил2-нафтиламина . Выход 37%.Example 4. 30 g (0.165 mol) of benzenesulfonic acid sodium salt, 56 g (0.33 mol) of sodium 2-naphthylamide and 36 g (0.25 mol) of 2 naphthylamine are heated at 400 ° C for 20 h. The reaction mixture is worked up analogously to the example 3. 13.8 g of N-phenyl 2 naphthylamine are obtained. Yield 37%.
