Abstract

Способ получения нерасплывающегося кристаллического пантотената кальция, который включает стадии (1) перемешивания пересыщенного водного раствора, содержащего пантотенат кальция в количестве 60% (мас./мас.) или более, например, при помощи измельчающей мельницы с получением суспензии кристаллов; и (2) высушивания суспензии. Может быть эффективно получен нерастекающийся кристаллический пантотенат кальция, который по существу не содержит органического растворителя.Международная заявка была опубликована вместе с отчетом о международном поиске.
