Description
те добавл ют 1 г-мол сульфолена. Реакционную смесь нагревают 2,5 час в бане при 95- 100°С. Затем реакционную смесь нейтрализуют концентрированной НС1, осадок NaCl отфильтровывают и фильтрат разгон ют из колбы Арбузова. Первые две фракции представл ют собой избыток спирта и промежуточно образовавшийс сульфолен-2, которые можно использовать дл следующего опыта. Треть фракци вл етс р-е-октафторпентоксисульфоланом . Выход 25-27%, константы его следующие: т. кип. 140°С/0,08, п 1,4035, df 1,6191, MRD найдено 52,85, вычислено 52,25.those add 1 gm sulfolene. The reaction mixture is heated for 2.5 hours in a bath at 95-100 ° C. Then the reaction mixture is neutralized with concentrated HC1, the NaCl precipitate is filtered off and the filtrate is dispersed from the Arbuzov flask. The first two fractions represent an excess of alcohol and an intermediately formed sulfolene-2, which can be used for the next experiment. The third fraction is p-e-octafluoropentoxysulfolane. Yield 25-27%, its constants are as follows: so kip. 140 ° C / 0.08, p 1.4035, df 1.6191, MRD found 52.85, calculated 52.25.
