己二酸的发展在我国存在很大空间

Exist Greater Dimension In The Development of Adipic Acid

简要介绍了己二酸在国内外的生产情况,并着重于近年来己二酸合成工艺路线进展及消费状况。全球己二酸产量约304万t/a。在2005年,我国己二酸生产能力约为25万t/a,需求量达31万t左右,预计2010年国内总需求量约为60万t,但产量将只有50万t左右,缺口较大。主要是我国尼龙和聚氨酯行业的发展,对己二酸的需求日益增多,每年都需要进口,所以己二酸在我国仍有一定的发展空间。

The global production capacity of adipic acid was 3.04 million tons per year in 2005 mainly used for nylon 66. The domestic production capacity of adpic acid was 0.25 million tons per year, and the consumption was about 0.31miUion tons in 2005, with 0.60 million tons in 2010. the progress of synthesis technique production situations, current consumption and technological progress of green synthesis of adlipic acid was introduced emphatically. Several production processes such as nitric acid oxidation of KA oil , air oxidation and cyclohexane direct oxidation are introduced.
