2、川,選擇Y直接排放,不但浪費(fèi)資源,而且污染環(huán)境。參考國(guó)內(nèi)外的文獻(xiàn),對(duì)羅紅霉素工藝路線進(jìn)行了沒(méi)計(jì),不但要獲得較高的產(chǎn)品收率,而且要對(duì)溶劑進(jìn)行回收,避免污染環(huán)境,達(dá)到清潔生產(chǎn)。關(guān)鍵詞:紅霉素肟;醚化;羅紅霉素;工藝設(shè)計(jì)。-1-鐘煒:年產(chǎn)300噸羅紅霉素原料藥工藝設(shè)計(jì)Thetechnologydesignoftheerythromycinproduced300tonsperyearzhongwei(AnhuiUniversityofTechnology&ScienceThebiochemistryengineeringdepartmentwuhu2410
