Claims (1)

Способ получения водорастворимых, физиологически совместимых сложных эфиров крахмала путем перевода крахмала в результате кислотного или энзимного гидролиза в частичный гидролизат со средним молекулярным весом Mw в области от 10000 до 500000 дальтон, этот гидролизат ацилируют в водном растворе ангидридом или галогенидом алифатической монокарбоновой кислоты с 2-4 атомами углерода или алифатической дикарбоновой кислоты с 3-6 атомами углерода или их смесью и подщелачивающим средством до молярного замещения в области от 0,1 до 1,0 моль/моль.Из полученной таким образом реакционной смеси удаляют соли. Полученный таким образом сложный эфир крахмала очень хорошо подходит для клинических, особенно парентеральных, и диетических применений.A method of producing water-soluble, physiologically compatible starch esters by converting starch through acidic or enzymatic hydrolysis to a partial hydrolyzate with an average molecular weight Mw in the range from 10,000 to 500,000 daltons, this hydrolyzate is acylated in an aqueous solution with anhydride or an aliphatic carbon monoxide carbon halide carbon atoms or aliphatic dicarboxylic acid with 3-6 carbon atoms or their mixture and alkalizing agent to a molar substitution in the range from 0.1 to 1.0 mol / mol. From semi ennoy thus the reaction mixture was removed salts. The starch ester prepared in this way is very well suited for clinical, especially parenteral, and dietary applications.
