Latest Patents

Brill's latest patents include a process for producing aminodiphenylamines. This invention relates to the production of aminodiphenylamines that achieve good yields and high purity levels when aromatic amines are reacted with nitrohalobenzenes in the presence of a palladium catalyst and a base. The product obtained is subsequently hydrogenated with hydrogen. Another significant patent involves the production of optionally substituted 4-aminodiphenylamines. This process entails reacting optionally substituted aniline with optionally substituted nitrobenzene in the presence of water and/or alcohols and organic and/or inorganic bases. The resultant nitro- and/or nitrosodiphenylamine is then catalytically hydrogenated in the presence of water, ensuring effective isolation of the 4-aminodiphenylamine.
