摘要
降低系统中水的含量 ,使乙醛的生成量明显降低 ,并减少了乙炔的消耗 ;采用新技术提高了乙醛的回收量 ,使醋酸消耗下降。
Reduction of the water content in system decreases the formation amount of acetaldehyde remarkable and also cut down the consumption of acetylene. The new technology adopted will improve the recovery yield of acetaldehyde and reduce the consumption of acetaldehyde .
