Oximes are used for purification of carbonyl compounds as well as to protect carbonyl compounds in the synthesis of carbonyl compounds. Oximes can be also synthesized from noncarbonyl compounds. Various methods, including acidcatalytic hydrolysis, reductive deoximation and oxidative deoximation have been developed for these preparations of oximes, ketones and aldehydes as its byproducts. However, these conventional methods pose environmental concerns regarding release of chemical pollutants. Therefore, the development of clean and highly efficient catalytic process for deoximation reactions is needed. In this study, immobilized ionic liquid resin (Im-IL-resin) which has carboxylic functional group was synthesized and evaluated for the deoximation reaction. The synthesized resins were characterized by FT-IR, SEM and TGA. Im-IL-resin and commercial Amberlyst-15 resin were compared for the deoximation both in batch and column reactor. Although deoximation yield using Im-IL-resin was similar to that of commercial acidic catalytic resin, Amberlyst-15, the deoximation reaction rate obtained was at least two times higher than that of Amberlyst-15 in batch reaction. In addition, the products could be efficiently separated in reactive column packed with Im-IL-resin whereas the products were not able to be separated with commercial Amberlyst-15 resin.
