Description

Известен способ алкилировани  фено.та нзобутиленом в прнсутсгвии катионообменной смолы (авт. св. Ло 109978). Примен ема  в качестве катализатора ионообменна  смола КУ-2 позвол ет осуществл ть только периодический процесс алкилировани  и не исключает протекани  побочных процессов, в частности процессов полимеризации и диалкилировани .The known method of alkylation with pheno. Isobutylene in the process of cation-exchange resin (ed. St. Lo 109978). The ion-exchange resin KU-2 used as a catalyst allows only the periodic alkylation process to be carried out and does not exclude the occurrence of side processes, in particular, polymerization and dialkylation processes.

Предложенный способ алкилировани  фенола изобутиленом свободен от указанных недостатков и заключаетс  в том, что в качестве катализатора используют катионообменную смолу, нанесенную на бентонит.The proposed method for the alkylation of phenol with isobutylene is free from these drawbacks and consists in using a cation exchange resin applied on bentonite as a catalyst.

При этом способе более эффективно используетс  катионообменна  смола; исключаютс  побочные процессы полимеризации, диалкилировани  и др; повышаютс  механические свойства катализатора; предложенна  форма катализатора более удобна дл  промышленного производства .This process uses cation exchange resin more efficiently; side processes of polymerization, dialkylation and others are excluded; improved mechanical properties of the catalyst; The proposed catalyst form is more convenient for industrial production.

При приготовлении катализатора катионат размалывают, просеивают через сито 100-200 меш и в порошкообразном состо нии замешивают с бентонитом на воде в раьных количествах по весу (1 : 1). Тестообразную массу пропускают через пресс и получают палочки диаметром 4-6 мм, которые сушат в сушильном шкафу при 100-120° в течение 8-10 час. Высушенный катализатор разламывают на кусочки длиной 4-б мм и загружают в соответствующий реактор, приспособленный дл  алкилировани  в потоке. Реакци  алкилировани  протекает при 80-140 Алкилированный продукт получаетс  с лучшей окраской, чем при периодическом алкилировании с катализатором по авт. св. № 109978.In the preparation of the catalyst, the cationate is milled, sieved through a sieve of 100-200 mesh, and in a powdery state, it is kneaded with bentonite in water in porous amounts by weight (1: 1). The pasty mass is passed through a press and get sticks with a diameter of 4-6 mm, which are dried in a drying cabinet at 100-120 ° for 8-10 hours. The dried catalyst is broken down into pieces with a length of 4-mm and loaded into an appropriate reactor adapted for alkylation in the stream. The alkylation reaction proceeds at 80-140. The alkylated product is obtained with a better color than with periodic alkylation with a catalyst according to the author. St. No. 109978.

Выход целевого продукта - третичНого бутилфенола достигает 80%, причем не происходит ни полимеризации, ни образовани  диалкилпроизводных . Скорость подачи фенола 0,6 -- /чThe yield of the desired product, tertiary butylphenol, reaches 80%, and neither polymerization nor the formation of dialkyl derivatives occurs. Phenol feed rate 0.6 - / h

по отношению к чистому катионату в два раза больше. Содержание точного фенола в сыром продукте алкилировани  10-15%. Фенол ко отдел етс  при перего-нке и может быть возвращен в произво; Описываемый катализатор может найти применение на неф мических предпри ти х, выпускающих алкилфенолы дл  произво синтетических смол, присадок и т. д.in relation to the pure cationate twice. The exact phenol content in the raw alkylation product is 10-15%. Phenol is separated during the exchange and can be returned to production; The described catalyst can be used in petrochemical plants that produce alkylphenols for the production of synthetic resins, additives, etc.
