Abstract
The invention relates to the method of obtaining oxiethylamidon which is used as a remedy for enlarging the volume of blood flame.The goal of the invention is to increase the purity of the product with a special destination. The method of obtaining oxiethylamidon is achieved by reciprocal action of destructive amidon with oxide ethylene in the atmosphere of inert gas in basic medium with prior neutralization of the reactant mixture. At the same time oxiethylamidon is extracted from reactant mixture with the help of dimethylformamid with multiple reprecipitating, it is desirable 5-6 times by means of acetone.
