发明名称 SYNTHESIS OF A MIXTURE OF SULFATED ESTROGENS USING A SULFUR TRIOXIDE COMPLEX
摘要 A process of producing a stable composition comprising a mixture of sulfated estrogens. The mixture of sulfated estrogens may comprise sulfated alkali metal salts of .DELTA.8,9-dehydroestrone, estrone, and derivatives thereof or other estrogens. The process comprises the steps of sulfating such mixture of alkali metal salts of .DELTA.8,9-dehydroestrone, estrone, and derivatives thereof with a sulfur trioxide complex and adding tris(hydroxymethyl)aminomethane.
