        [顺酐生产工艺]顺酐的气相氧化产生方法

        发布时间:2019-11-24 点击次数:
               马来酸酐根据正丁烷的液相空气氧化造成,全过程将甲基转换为羧酸盐并使骨架图脱氢,该方式的可选择性体现了马来酸酐以及共轭双键管理体系的稳健性。传统式上,顺酐生产商是根据苯或别的芳族化学物质的空气氧化造成的,截止2006年,只能极少数中小型加工厂再次应用苯。
          在二种状况下,将苯和丁烷添加热空气中,使化合物在高溫下根据金属催化剂床。操纵气体与氮氧化合物的占比以避免化合物引燃。五氧化二钒和三氧化钼是用以苯方式的金属催化剂,而硫酸铵钒用以丁烷方式:C4H10\#+ 3.5O2→C4H2O3\#+4H2OΔH= -1236kJ / mol
          关键的市场竞争全过程必须丁烷的彻底点燃,这类转换的放热反应是一部分空气氧化的二倍。
