Title: Dhiraj Sudesh Sood: Innovator in Catalytic Processes
Introduction
Dhiraj Sudesh Sood is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of chemistry, particularly in catalytic processes. With a total of 2 patents, his work focuses on innovative methods for the production of valuable chemical compounds.
Latest Patents
Sood's latest patents include a catalytic system and method for the coupling of aromatic compounds. This catalytic process allows for the production of biphenyl and its derivatives by coupling substituted or unsubstituted monoaryl compounds. The process utilizes a catalytic system that comprises at least one Pd (II) compound and a strong acid or a mixture of acids. It provides high conversions and selectivity under mild temperature conditions and short reaction times. The strong acid or mixture of acids used has a Hammett acidity of less than about -10, which contains a predominant amount of counterions that form a weak ligand complex with palladium (II). This method is highly selective for the formation of desired biaryl isomers, such as 4,4'-isomers, allowing control over the relative amounts of isomers in the final product.
Another significant patent by Sood is directed to a process for the carbonylation of an arylene to an arylaldehyde, such as converting toluene to tolualdehyde. This process is conducted in the presence of a solid acid catalyst and involves carbonylating toluene with carbon monoxide or a source of carbon monoxide. The reaction occurs at temperatures ranging from -40°C to 200°C and at pressures between 20-4000 psig.
