| Abstract: | Acetic acid and aqueous chromium sulfate are made by waste chromic paste, which came from production of pregnenolone, acetate with steroid saponin, adopting new recorery technology. The preparation methods and technologcal process are determined. The acetic acid is returned to use, then aqueous chromium sulfate may be used to make contained chromium metal complex dyes and chromic system catalyst. |
