摘要
醋酐是一种重要的有机化工原料,化学性质非常活泼,主要用于制造醋酸纤维素。此外它还可用作医药、染料、香料、漂白剂、乙酰化剂、脱水剂和聚合反应的引发剂等,用途十分广泛。目前,醋酐的工业生产方法主要有乙醛氧化联产法、醋酸裂解法和醋酸甲酯羰基合成法3种。其中醋酸裂解法是目前国内外最主要的生产方法,乙醛氧化联产法正在逐渐被淘汰,醋酸甲酯羰基合成法是醋酐工业生产今后的主要发展方向。
In 2006,the total production capacity of acetic anhydride in the world was about 2.384 mt/a,with total consumption about 1.885 mt/a.It is forecasted that the total consumption of acetic anhydride in the world will reach about 2.0 mt/a in 2011.At present,the production capacity of acetic anhydride in China is about 0.33 mt/a,with total consumption about 0.238 mt/a in 2006.In 2011, the total production capacity and consumption of acetic anhydride in China will reach about 0.6 mt/a and 0.4 mt/a respectively.According to the status and problems existing in the production of acetic anhydride in China,suggestions for the development of acetic anhydride are put forward.
