Description
ной реакции неоднократно. Этот катализатор получают нанесением РЬС1з-«Н20 на уголь и восстанавливают в автоклаве перед гидрированием .reaction repeatedly. This catalyst is prepared by applying PbCl3 - "H2O to coal and is reduced in an autoclave before hydrogenation.
Примеер 1. 7 г метилен-а-бисциклогексанона в 40 мл этилового спирта гидрируют в автоклаве емкостью 150 мл при комнатной температуре и давлении 80 атм в присутствии 5% Ph/C (0,5 г катализатора, что составл ет 0,3% металла по отношению к исходному веществу ). Гидрирование происходит 2,5 час. Продукт гидрировани отдел ют от катализатора и растворител и подвергают вакууммной разгонке; выход пергидроксантена составл ет 97%.Example 1. 7 g of methylene-a-biscyclohexanone in 40 ml of ethyl alcohol are hydrogenated in a 150 ml autoclave at room temperature and a pressure of 80 atm in the presence of 5% Ph / C (0.5 g of catalyst, which is 0.3% of metal in relation to the original substance). Hydrogenation occurs 2.5 hours. The hydrogenation product is separated from the catalyst and solvent and subjected to vacuum distillation; the yield of perhydroxanten is 97%.
Идентификаци продукта гидрировани осуществлена по данным ТС-хроматографии, по температуре кипени , показателю преломлени , данным элементного анализа и ИКспектроскопии .The hydrogenation product was identified by TC chromatography, boiling point, refractive index, elemental analysis, and IR spectroscopy.
Катализатор, промытый растворителем, может быть использован дл дальнейшего гидрировани .The catalyst, washed with a solvent, can be used for further hydrogenation.
Пример 2. Гидрирование метилен-а-бисциклогексанона провод т в услови х, аналогичных описанным в примере 1, но в присутствии катализатора, использованного в опыте 1. Выход пергидроксантена 93%.Example 2. The hydrogenation of methylene a-biscyclohexanone is carried out under conditions similar to those described in example 1, but in the presence of the catalyst used in experiment 1. The yield of perhydroxantene is 93%.
Пример 3. Гидрирование метилен-а-бисциклогексанона осушествл ют в услови х, Example 3. The hydrogenation of methylene a-biscyclohexanone is carried out under conditions
аналогичных описанным в примере 1, но в нрисутствии катализатора после опыта 2. Выход пергидроксантена 95%.similar to those described in example 1, but in the presence of a catalyst after experiment 2. The yield of perhydroxanten is 95%.
Пример 4. Гидрирование метилен-а-бис:ип логексанона провод т в услови х, аналогичных описанным в примере 1, но при давлении 40 атм. Врем гидрировани 4 час. Вы .ход пергидроксантена 95%.Example 4. Hydrogenation of methylene-a-bis: type of logexanone is carried out under conditions similar to those described in example 1, but at a pressure of 40 atm. Hydrogenation time 4 hours. You are going perhydroxanten 95%.
Использование предлагаемого способа по сравнению с сушествующим обеспечивает следующие преимущества:The use of the proposed method in comparison with the existing provides the following advantages:
м гкие услови гидрировани - комнатна температура и давление 40-80 атм;mild conditions of hydrogenation — room temperature and pressure 40–80 atm;
использование легкодоступного растворител ;use of readily available solvent;
использование катализатора, получаемого простым способом.using a catalyst obtained in a simple way.
