Abstract

В данном документе раскрыт способ получения кристаллов тригидрата оксида алюминия из технологического потока для извлечения тригидрата оксида алюминия, где водную эмульсию, содержащую алкил- или алкенилянтарный ангидрид, добавляют к технологическому потоку для извлечения тригидрата оксида алюминия, при этом водная эмульсия практически не содержит минеральных масел. Способ обеспечивает снижение процентного содержания кристаллов тригидрата оксида алюминия со средним объемным диаметром менее приблизительно 45 мкм по сравнению с процентным содержанием кристаллов тригидрата оксида алюминия, полученных в отсутствие водной эмульсии алкил- или алкенилянтарного ангидрида.
