Abstract
Способ получения диальдегиддекстрана, включающий окисление водного раствора декстрана перманганатом калия в кислой среде при нагревании, удаление примесей путем отделения жидкости от осадка, выпавшего на стадии окисления декстрана и высушивание диальдегиддекстрана, отличающийся тем, что непосредственно после удаления примесей водный раствор диальдегиддекстрана сушат путем распылительной сушки.A method of producing dialdehydedextran, comprising oxidizing an aqueous solution of dextran with potassium permanganate in an acidic medium when heated, removing impurities by separating the liquid from the precipitate that has precipitated in the oxidation stage of dextran and drying dialdehydedextran, characterized in that immediately after removing the impurities, the aqueous solution of dialdehydedextran is dried by spray drying.
