Latest Patents
One of Lindley's latest patents is focused on color control and stability in acetaminophen. This method provides a way to purify crude N-acetyl-para-aminophenol (APAP) that contains color bodies or their precursors. The process involves forming a solution of crude APAP and then contacting it with substoichiometric quantities of an acetylating agent. This interaction converts the color bodies into stable, colorless substances without converting the APAP into other compounds.
Another significant patent by Lindley is a process for the acylation or alkylation of aromatic compounds in hydrogen. This continuous process utilizes hydrogen fluoride as a reaction medium, where the aromatic compound is sufficiently insoluble, leading to a two-phase reaction. The invention emphasizes a multi-stage process that can either consume the aromatic compound feed entirely or recycle unreacted compounds, showcasing the versatility and efficiency of the method.
