Latest Patents

Tadokoro holds a patent for a process for refining methacrylic acid. This process involves oxidizing methacrolein catalytically in a vapor phase to create a methacrylic acid-containing gas. The gas is then cooled and condensed into an aqueous methacrylic acid solution. An organic solvent is added to this solution to facilitate an extraction operation, resulting in a refined extract. The extract is subsequently mixed with water, separated into organic and water phases, and the organic phase is distilled. This method allows for the production of highly refined methacrylic acid with minimal dibasic acids, such as maleic acid and citraconic acid, while also reducing waste.
