Latest Patents
Her latest patents include a groundbreaking method for the single-step hydrogenation of nitrobenzene to p-aminophenol. This invention provides a process for preparing p-aminophenol by hydrogenating nitrobenzene in the presence of an aqueous acid over a mono or bimetallic nickel catalyst. The reaction occurs at a temperature range of 80-120°C for a period of 1 to 4 hours. The resulting mixture is then extracted with organic solvents such as ethyl acetate, cyclohexane, or toluene to separate the aqueous layer containing p-aminophenol, which is neutralized with ammonia solution to recover the solid product. Another patent focuses on a single-step process for the preparation of p-aminophenol by contacting a mixture of nitrobenzene and water with hydrogen over a solid acid catalyst. This method also involves extracting the reaction mixture with an organic solvent and concentrating the aqueous layer to obtain the final product.
