| Abstract: | The catalytic synthesis of 2,4,6-triibutyl-1,3,5-trioxane through the cyclotrimerization of isovaleradehyde by the ionic liquids of Cl/FeCl_3 was studied.The results showed that the conversion of isovaleraldehyde and the selectivity of 2,4,6-triisobutyl-1,3,5-trioxane achieved 76% and 95%,respectively.The optimal conditions of the reaction(at room temperature for 1 h) were as follows: isovaleraldehyde was 25 g and (Cl/FeCl_3) [x(FeCl_3)=0.67] was 2 g.The ionic liquids of Cl/FeCl_3 could be reused five times without decrease of the conversion and the selectivity. |
