    Abstract: PURPOSE: Provided are an aluminosilicate sphere nano particle, a manufacturing method thereof, and a method for acrylic acid using the same, wherein the aluminosilicate sphere nano particle can easily transfer a reactant to the inside of a pore, minimize material transfer resistance, and have wide specific surface area while maintaining an acid characteristic of the aluminosilicate. CONSTITUTION: An aluminosilicate sphere nano particle has an open pore structure in a form wherein the size of the particle increases in a direction in which the radius of the particle increases from the center of the particle. The specific surface area of the nano particle is at least 100 m^2/g. The manufacturing method of the aluminosilicate sphere nano particle comprises the steps of: performing a first hydrothermal process on a solution including a silica precursor, a polar solvent, a non-polar solvent, an ionic surfactant and an alkaline compound in a pressure vessel; controlling the pH of the first hydrothermal process treated solution to 2-7 using an acidic aqueous solution; inserting an aluminum precursor into a pH-controlled solution; and performing a second hydrothermal process on the solution into which aluminum precuesor is inserted in the pressure vessel.
