This process needs to solve the main problem is to realize efficient synthesis CH3COOCH3 and CO. Design the methyl acetate carbonyl compounds into the process flow into the repayment period of the main equipment braising apparatus to carry on the design.22024 年 5 月 29 日下载后可任意编辑Keywords: vinegar anhydride chemical raw materi...
