Abstract
Invenţia se referă la procedeul de obţinere a oxietilamidonului care se foloseşte în calitate de remediu pentru majorarea volumului plasmei sângelui. Scopul invenţiei constă în majorarea gradului de puritate a produsului cu destinaţie specială. Procedeul de obţinere a oxietilamidonului se realizează prin acţiunea reciprocă a amidonului destructiv cu oxidul de etilen în atmosfera gazului inert în mediul bazic cu neutralizarea ulterioară a amestecului reactant. Totodată oxietilamidonul se extrage din amestecul reactant cu ajutorul dimetilformamidei cu reprecipitarea multiplă, de preferinţă de 5-6 ori cu ajutorul acetonei.
