With a total of 3 patents, her work has advanced the efficiency and economics of chemical production processes.
Latest Patents
One of her latest patents is for an "Integrated process for the production of aminoacetonitriles." This invention focuses on an integrated process that utilizes a crude, unpurified reactor product stream from a hydrogen cyanide reactor, along with a formaldehyde stream. The process involves feeding these streams directly to a reactive absorber, which, combined with an additional nitrogen source and a controlled pH aqueous solution, produces aminoacetonitriles in high yields. This innovative approach eliminates the need for intermediate recovery and purification processes typically associated with conventional production methods.
Another significant patent is for a "Process for the production of iminodiacetonitrile." This invention also employs an integrated process where a crude, unpurified reactor gas stream from a hydrogen cyanide reactor is fed directly to a reactive absorber. By adding additional ammonia and acidified water, the process yields iminodiacetonitrile efficiently. This method improves the economics of production by removing costly intermediate recovery and purification steps.
