【Abstract】 The catalytic synthesis of 2,4,6-triibutyl-1,3,5-trioxane through the cyclotrimerization of isovaleradehyde by the ionic liquids of Cl/FeCl₃ 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/FeCl₃） [x（FeCl₃）=0.67] was 2 g.The ionic liquids of Cl/FeCl₃ could be reused five times without decrease of the conversion and the selectivity.更多还原
