| Abstract: | This paper reported that a solid superacid TiO 2/SO 4 2- catalysis synthesized isobutyl butyrate for buthlacid and isobutyl alcohol. It was researched that the acid-alcohol rate, temperature, time, quantity and repeatly application of catalyzes had influene upon yield of esterication reaction. The experimental results showed that the yield of esterication reaction to producting isobutyl butyrate was larger than 88% on appropriate technological condition. The production was characterizated by IR,it was a pure isobutyl butyrate. The synthesizing route have characteristics of simple technology, less pollute and repeatly applited of catalyzes. |
