摘要： The present invention provides a method of preparing organic acids from aldehyde compounds by means of liquid phase oxidation which converts an aldehyde group of a compound harboring one or more aldehyde groups into a carboxyl group by using an ionic liquid as a reaction solvent or a reaction catalyst. According to the present invention, the ionic liquid is less volatile even at high temperature and stable against heat, enhancing conversion rate and selectivity and further increasing yield. In addition, the ionic liquid can be easily separated and recycled from the reactant and product.
