Description
(54) СПОСОБ ПОЛУЧЕНИЯ СТИРОЛХЛОРГИДРИНА(54) METHOD OF OBTAINING STYROLHLOROHIDRINE
Экстракт смешивают с отсто вшимс стиролхлоргидрином - сырцом, регенерируют растворитель, анализируют хроматографическим методом остаток.The extract is mixed with settled raw styrene chlorohydrin, the solvent is regenerated, and the residue is analyzed by the chromatographic method.
Состав стиролхлоргидрина - сырца приведен в табл. 1.The composition of styrene chlorohydrin - raw is given in table. one.
Таблица 1Table 1
ЧТО составл ет 20% от первоначальной концентрации в реакционной массе.WHAT is 20% of the initial concentration in the reaction mass.
Состав и выход целевого продукта аналогичен примеру 2лThe composition and yield of the target product is similar to example 2l
Таблица 2table 2
Выход стиролхлоргидрина по стиролу составл ет 90%. Соотношение воды к водно-флевому раствору реакционной массы 1:1. Общее количество выделенного стиролхлоргидрина из реакционной массы составл ет 97,3 вес. %.The styrene chlorohydrin yield for styrene is 90%. The ratio of water to water-neutral solution of the reaction mass is 1: 1. The total amount of styrene chlorohydrin released from the reaction mass is 97.3 wt. %
Пример 2. В услови х, аналогичных услови м примера 1, на орошение скруббера подают 0,2 л/ч свежей воды и 1,2 л/ч реакционной массы после выделени из нее стиролхлоргидрина. Содержание поваренной соли в :реак Ц|ионной массе составл ет 20,4%. Соотношение воды к реакционной массе составл ет 1:1. Выход стиролхлоргидрина по стиролу 80 вес. %.Example 2. Under conditions similar to those of Example 1, 0.2 l / h of fresh water and 1.2 l / h of the reaction mass are supplied to the scrubber spray after the styrene chlorohydrin is removed from it. The content of table salt in: the reaction of CI ion mass is 20.4%. The ratio of water to the reaction mass is 1: 1. The output of styrene chlorohydrin styrene 80 weight. %
Состав , стиролхлорги рина - сырца приведен в табл. 2.The composition, styrene-chlorinated raw material is given in Table. 2
Пример 3. В услови х, аналогичных услови м примера 1, из реакционной массы после отстаивани экстрагируют растворенный стиролхлоргидрин 2 об. % дихлорэтана до содержани целевого продукта 15 т/л.Example 3. Under conditions similar to those of Example 1, after settling, extracted styrene chlorohydrin 2 vol. % dichloroethane to a target product content of 15 t / l.
