Abstract: This paper presents a novel production process of alumina by using isooctanol. The reaction rate of isooctanol and aluminum is very fast. It is simple to purify triisooctanoxyl aluminum，to reuse isooctanol and to control the physical and chemical properties of alumina. This production process can be easily commerialized. The catalyst using alumina obtained by this method has the performance as good as that of the catalyst using imported SB alumina.
