Latest Patents
Yeong-Cheong Lee holds a patent for the "Production of carboxylic acids from carbonylation of alcohol." This invention relates to an improved process for synthesizing carboxylic acids by the carbonylation of alcohol. An alcohol such as methanol is reacted with carbon monoxide in a liquid reaction medium containing a rhodium (Rh) catalyst stabilized with haloacetic acid, especially trifluoroacetic acid (TFAA), along with alkyl iodide such as methyl iodide (MeI) in specified proportions. The present reaction system is characterized by unexpectedly high catalyst stability and a high reaction rate for the formation of acetic acid. The improvement resides in the employment of trifluoroacetic acid as the catalyst promoter at a temperature from 180°C to 200°C. The primary advantage of the catalyst system is the enhancement of the rate of carbonylation. Additionally, the catalyst system is readily soluble and thermally stable, making it resistant to deposition. Yeong-Cheong Lee has 1 patent to his name.
