Abstract
The invention relates to a simple technical process used for preparing high-pure ozagrel sodium crystal. The process basically includes the following steps: the raw ozagrel sodium is added into ethanol and then heated for dissolving; active carbon is added for decoloring and filtering is carried out under the heated condition; the filtrate is filtered in a refined way by a microfiltration membrane, collected, heated first and then cooled slowerly; and the temperature is controlled to be 25 DEG C to 60 DEG C for temperature-preservation crystallization and then the temperature is reduced slowly and cooled for crystallization; finally the crystal is collected. The crystal prepared by the method is high in purity and yielding and low in impurity content; therefore the therapy effect of the product is effectively enhanced and the cost is reduced simultaneously.
