| Abstract: | Diisooctyl maleate was synthesized by titanium tetraethoxide as catalyst.Structures of the product was characterized by IR and element analysis.The optimal conditions were found as follows: n(maleic anhydride):n(iso-octanol)=1:3.0,reaction time 0.5 h at refluxing temperature,0.5% catalyst based maleic anhydride,15% toluene based on maleic anhydride and iso-octanol.Under these conditions,the extent of esterification reached at least 99%.The results showed that titanate is a good catalyst having high reactivity under mild conditions. |
| Keywords: | titanium tetrathoxide diisooctyl maleate esterification maleic anhydride iso-octanol |
