Abstract

Отделение твердых веществ от водных растворов 1,4-бутиндиола осуществляют тем, что водный раствор бутиндиола, содержащий твердые вещества, путем орошения пропускают через колонну и при этом вводят в контакт с растворителем, который обладает меньшей плотностью, чем раствор бутиндиола, содержащий твердые вещества, при этом образуется вторая фаза, а растворитель подают снизу вверх противотоком к водному раствору бутиндиола, твердое вещество концентрируется на границе раздела между водным бутиндиолом и растворителем, и твердое вещество удаляют путем отбора смеси водного бутиндиола и растворителя.Международная заявка была опубликована вместе с отчетом о международном поиске.
