Latest Patents
One of his latest patents is a method for producing methacrolein and/or methacrylic acid. This invention relates to a method characterized by the catalyst filling length of a dehydration catalyst layer being 3 to 20% of the catalyst filling length of an oxidation catalyst layer. This method allows for the production of methacrolein and/or methacrylic acid by dehydration reaction and catalytic gas phase oxidation reaction, increasing the conventional yield from approximately 80% to 81-82% even at relatively low reaction bath temperatures of around 355°C. Another notable patent is for a catalyst for producing methacrylic acid and its preparation method. This catalyst is designed to achieve high yield and selectivity by using methacrolein, isobutylaldehyde, or isobutyric acid in gas phase catalytic oxidation. The catalyst contains essential active components such as Mo, V, P, Cu, Cs, and N, and is prepared using a cesium weak acid salt or cesium hydroxide as the Cs raw material and ammonium acetate as the NH raw material.
