Latest Patents

Kenneth's latest patents include a process for the preparation of 4-sulfo-2-chlorobenzoic acid and an oxidation process aimed at producing benzophenones or substituted benzophenones. This innovative process seeks to provide an alternative method that avoids the drawbacks of previous techniques, such as the excessive use of aluminium chloride catalysts or nitric acid. The method involves oxidizing a diphenyl methane starting material in a hydrophobic phase through a photolytic process. This is achieved by contacting it with an aqueous phase containing HBr and H₂O₂, utilizing specific wavelengths of light to dissociate bromine into radicals. The process is designed to recover the benzophenone product effectively while retaining most of the bromine in the aqueous phase for reuse.
