Abstract
Provided are a method for producing boehmite nanoparticles and an apparatus for producing the same, and more particularly, a method for producing boehmite nanoparticles and an apparatus for producing the same, which allow continuous production of nano-sized boehmite nanoparticles in a uniform size. The method for producing boehmite nanoparticles includes (S1) supplying a mixture including an aluminum hydroxide and an organic acid to a reaction unit; and (S2) heating and pressurizing the mixture supplied to the reaction unit simultaneously and sequentially.
Claims14
A method for producing boehmite, the method comprising:
- (S0) reacting a raw material comprising an aluminum alkoxide and an organic acid to produce a mixture comprising an aluminum hydroxide and an organic acid;
- (S1) supplying the mixture comprising the aluminum hydroxide and the organic acid to a reaction unit;
- and
- (S2) heating and pressurizing the mixture supplied to the reaction unit simultaneously or sequentially,
- wherein the organic acid comprised in the raw material of (S0) is the same as the organic acid comprised in the mixture of (S1), and
- wherein the method produces rod-shaped boehmite nanoparticles having an average-short axis diameter of 1 to 10 nm and an average long axis length of 30 to 100 nm.
