Latest Patents

Meilchen holds a patent for a process titled "Removal of carbonyl impurities from a carbonylation process stream." This invention describes a method to reduce carbonyl impurities in a carbonylation reaction for the production of acetic acid. The process involves treating the methyl iodide recycle stream directed to a carbonylation reactor. By reacting the methyl iodide stream with an aqueous amino compound, carbonyls are converted into water-soluble nitrogenous derivatives. This method effectively separates the organic methyl iodide phase from the aqueous derivative phase, allowing for the distillation of the methyl iodide phase to remove heavier impurities. The treatment significantly reduces the carbonyls present in the acetic acid product, enhancing the overall quality of the output.
