Latest Patents
Jong-Hyun Chae holds a patent for a method of producing aromatic carboxylic acids by oxidizing alkyl aromatic hydrocarbons or partially oxidized intermediates. This improved production method significantly enhances the yield and quality of aromatic carboxylic acid products. The process involves oxidizing alkyl aromatic substrates in a modified MC-type catalyst system, which includes additional components such as alkali or alkaline earth metals in an acetic acid medium. The use of carbon dioxide as a co-oxidant alongside oxygen allows for a more selective oxidation reaction, resulting in faster production under milder conditions. Notably, this method has shown remarkable improvements in the production of terephthalic acid from para-xylene, surpassing the expectations of current PTA producers. Furthermore, the invention includes an effective purification process to yield highly pure terephthalic or isophthalic acid by addressing impurities found in crude products.
