Abstract
Способ получения наночастиц сукцинатов хитозана, включающий взаимодействие хитозана и янтарной кислоты, с последующим выделением целевого продукта, согласно изобретению, готовят 0,11-0,17% раствор янтарной кислоты при комнатной температуре, фильтруют нерастворившуюся янтарную кислоту и вносят в полученный раствор предварительно очищенный низкомолекулярный хитозан 3,9 или 30 кДа, выдерживают при перемешивании со скоростью 200 об/мин в течение 2 ч, по окончании реакции прибавляют этанол и центрифугируют, твердый остаток фильтруют и сушат в вакуумном сушильном шкафу при температуре 30°C.A method of producing chitosan succinate nanoparticles, including the interaction of chitosan and succinic acid, followed by isolation of the target product, according to the invention, prepare a 0.11-0.17% succinic acid solution at room temperature, insoluble succinic acid is filtered and pre-purified low molecular weight is introduced into the resulting solution chitosan 3.9 or 30 kDa, kept under stirring at a speed of 200 rpm for 2 hours, at the end of the reaction, ethanol was added and centrifuged, the solid residue was filtered and dried in vac smart oven at a temperature of 30 ° C.
