Abstract

Альдольную конденсацию и дегидрацию проводят в реакторе с мешалкой 16, используя щелочной катализатор, такой как гидроксид натрия. Поток продукта реакции 23, содержащий как органическую, так и водную фазы, перегоняют (в колонке 25), получая гетерогенный азестроп, содержащий воду и альдегид. При конденсации и разделении фаз нижний водяной слой 34 может быть выражен из установки без необходимости проведения нейтрализации. Из нижней области дистилляционной зоны получают смесь 36 замещенного акролеина и раствора щелочного катализатора. Замещенный акролеин извлекают в качестве продукта 45, тогда как раствор катализатора 47 возвращают обратно в реактор альдольной конденсации. Часть 49 раствора катализатора удаляют, чтобы регулировать степень образования продуктов реакции Канниццаро.
