Description

руют 10%-ным pacTBOpOiM КОН (5 порций по 5 мл).Rout with 10% pacTBOpOiM KOH (5 servings of 5 ml).

2,4-ди-т/7ет.амилфенол выдел ют из реакционной массы экстракцией его 7 порци ми по 50 мл раствора Клайзена (раствор 35 г едкого кали, 25 мл воды в 100 мл метанола), с последующим подкислением концентрированной сол ной кислотой. Выделившеес  масло экстрагируют эфиром, эфирный раствор сушат над прокаленным сернокислым натрием.2,4-di-t / 7et. Amylphenol was separated from the reaction mass by extraction with 7 portions of 50 ml of Claisen solution (solution of 35 g of potassium hydroxide, 25 ml of water in 100 ml of methanol), followed by acidification with concentrated hydrochloric acid. The oil that is separated out is extracted with ether, and the ethereal solution is dried over calcined sodium sulphate.

После отгонки эфира получают 72,9 г (49,8%, счита  на вступивший в реакцию фенол ) 2,4-ди-т/;7ег.амилфенола; по 1.497, т. кип. 143-145°С/8 мм рт. ст.After distilling off the ester, 72.9 g (49.8% are obtained, calculated on the phenol which entered into the reaction) 2,4-di-t /; 7-amylphenol; on 1.497, t. Kip. 143-145 ° C / 8 mm Hg. Art.

Из ш,елочного раствора при подкислении и аналогичной обработке выдел ют 41,3 г (42%, счита  на прореагированный фенол) 4-трет, амилфенола. .For acidification and similar treatment, 41.3 g (42%, counting on the reacted phenol) 4-tert, amylphenol, are isolated from the polymer solution. .

Суммарный выход алкилированных продуктов 91,8%, счита  на вступивший в реакцию фенол.The total yield of alkylated products is 91.8%, based on the phenol that entered into the reaction.

Примеры 2, 3 и 4 провод т аналогично примеру 1, измен   состав и количество катализатора . Данные результатов опытов приведены в таблице.Examples 2, 3 and 4 are carried out analogously to example 1, varying the composition and amount of the catalyst. The results of the experiments are shown in the table.
