Abstract: The present invention relates to an apparatus for producing alcohols from olefins, comprising: a hydroformylation reactor wherein aldehydes are produced from olefins; a catalyst/aldehydes separator; a hydrogenation reactor wherein the aldehydes are hydrogenated to produce alcohols; and a distillation column. The hydroformylation reactor is equipped with a distributor plate, which has a broad contact surface for providing sufficient reaction area for reactants such as olefins and synthesis gas, and allows the reaction mixture to circulate and mix sufficiently, which contribute to excellent efficiency in terms of production of aldehydes. In addition, the hydrogenation reactor suppresses sub-reactions to improve the production yield of alcohols.

Abstract: 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.
