Изобретение относитс к нефтехи мическому синтезу/ в частиности к производству алкилфенолов.The invention relates to petrochemical synthesis (in particular, to the production of alkylphenols).
Известен способ получени алкилфенолов алкилированием фенолов олефинами в присутствии катализатора сульфокатионита модифицированного А1СЦ 1 .A known method for producing alkylphenols by alkylation of phenols with olefins in the presence of a catalyst of sulfonic cation exchanger modified A1SC 1.
Недостаток известного способа невысокий выход алкилфенолов с заместителем в ортоположение.The disadvantage of this method is the low yield of alkylphenols with a substituent in the ortho position.
Цель изобретени - повышение селективности процесса.The purpose of the invention is to increase the selectivity of the process.
Поставленна цель достигаетс тем, что используют алюминиевую соль сульфокатионита, в которой количество алюмини составл ет 0,4-3,0 вес.%.This goal is achieved by using an aluminum salt of a sulfonic cation exchanger, in which the amount of aluminum is 0.4-3.0 wt.%.
Катализатор.получают путем обработки катионита (КУ-2) воднымCatalyst. Get by treating cation exchanger (KU-2) with water
раствором, содержащим 10% НС 1и 1-15% А1СЦ, с последующей сушкой.a solution containing 10% HC 1 and 1-15% AlSC, followed by drying.
Пример 1. Катализатор процесса производства ортоалкилфенола готов т следующим образом.Example 1. The catalyst for the production process of orthoalkylphenol is prepared as follows.
Промышленный катионит (КУ-2} в количестве 100 мл заливают предварительно приготовленным раствором, содержащим 8% AlCl и 10% НС1. Через 10 ч раствор сливают, а катализатор промывают дистиллированной, водой до исчезновени иоиов хлора в промывной воде, высушивают при 100120°С в токе азота.Industrial cation exchanger (KU-2} in the amount of 100 ml is poured in previously prepared solution containing 8% AlCl and 10% HCl. After 10 hours, the solution is drained and the catalyst is washed with distilled water until the chlorine drops in the wash water, dried at 100120 ° С in a stream of nitrogen.
Другие образцы катализатора получают при обработке КУ-2 раствором, содержащим 1-15% А1С.Other samples of the catalyst are obtained by treating KU-2 with a solution containing 1-15% A1C.
Составы образцов катализаторов сведены в таблицу.The compositions of the samples of catalysts are summarized in table.
