摘要: A process for preparing a divinylarene oxide including (a) reacting (i) at least one divinylarene; (ii) at least one peroxycarboximidic acid; (iii) at least one solvent; and (iv) at least one basic compound, under reaction conditions to form a reaction effluent containing a divinylarene oxide product; and then (b) evaporating the reaction effluent of step (a) to form a concentrate containing the divinylarene oxide product; and wherein the concentrate separates into two liquid phases.
摘要翻译: 一种制备二乙烯基芳烃氧化物的方法,包括(a)使(i)至少一种二乙烯基芳烃反应; (ii)至少一种过氧羧酰亚胺酸; (iii)至少一种溶剂; 和(iv)至少一种碱性化合物,在反应条件下形成含有二乙烯基芳烃氧化物产物的反应流出物; 然后(b)蒸发步骤(a)的反应流出物以形成含有二乙烯基芳烃氧化物产物的浓缩物; 并且其中浓缩物分成两个液相。
