Description
Способ получени 4,4-диоксиднфеннлсульфида взаимодействием хлорида серы с фенолом в среде четыреххлористого углерода известен.The method for the preparation of 4,4-dioxynphenyl sulfide by reacting sulfur chloride with phenol in carbon tetrachloride is known.
С целью упрощени процесса и повышени выхода продукта, предлагаетс в качестве растворител использовать ароматические углеводороды, папример толуол.In order to simplify the process and increase the product yield, it is proposed to use aromatic hydrocarbons as a solvent, for example, toluene.
Пример. В колбу емкостью 500 мл с мешалкой , капельной воронкой п обратным холодильннком помещают 94 г (1 г-моль) фенола и 600 мл толуола, охлаждают эту смесь до 0°С и при О-2°С постепенно в течение 2 час к ней приливают раствор 51,5 г (0,5 г моль SCU в 50 мл толуола. После этого реакционную массу размешиваютExample. 94 g (1 g-mol) of phenol and 600 ml of toluene are placed in a flask with a capacity of 500 ml with a stirrer, a dropping funnel and a reverse fridge, cool this mixture to 0 ° C and at 0 -2 ° C gradually over 2 hours it is poured a solution of 51.5 g (0.5 g mol of SCU in 50 ml of toluene. Then the reaction mass is stirred
1,5 час, отфильтровывают выпавший в осадок 4,4-диоксидифенилсульфпд, а затем высушивают его нрн 60°С.1.5 hours, the precipitated 4,4-dioxydiphenylsulfopd is filtered off and then dried at nrn 60 ° C.
Выход 93--98 г ( от теор., счита на фенол). Продукт представл ет собой белое кристаллическое вещество с т. пл. 145- 246°С.Output 93--98 g (from theory., Counting on phenol). The product is a white crystalline substance with mp. 145-246 ° C.
