With a total of 5 patents to his name, Barman's work showcases his innovative approach to solving complex chemical processes.

Latest Patents

One of Barman's latest patents is a catalytic method for acrylate production. This method involves reacting ethylene gas in the presence of a metal precursor solution, which includes a base, an additive, a metal precursor, a solvent, and a ligand, all within an autoclave. The process results in the formation of a metal complex intermediate solution, which further reacts with carbon monoxide to produce an ester intermediate solution. This solution is then reacted to yield an acrylate salt product mixture, which is subsequently extracted. The reaction occurs at temperatures ranging from 100° C. to 200° C., utilizing tetrakis(triphenylphosphine)palladium(0) as the metal precursor. The concentration of this precursor in the solution is maintained between 0.0005M and 0.003M, with sodium formate serving as the additive and solvents selected from N-cyclohexyl-2-pyrrolidone, tetrahydrofuran, or their combinations. The turnover number achieved in this process is greater than or equal to 100.

Another significant patent involves catalyst systems that include meta-alkoxy substituted n-aryl bis-diphosphinoamine ligands. These systems are designed for the tetramerization of ethylene to produce 1-octene. The catalyst comprises a chromium compound coordinated with a ligand and a co-catalyst, which may include an organoaluminum compound. The ligand's chemical structure allows for various hydrocarbyl and heterohydrocarbyl groups, enhancing the versatility of the catalyst system.
