Title: Henry M Grotta: Innovator in Chemical Processes
Introduction
Henry M Grotta is a notable inventor based in Delaware, OH (US), recognized for his contributions to chemical processes. He holds a total of five patents, showcasing his innovative approach to solving complex problems in the field of chemistry.
Latest Patents
Among his latest patents is a method for purifying cresidine sulfonic acid by resin extraction. This method effectively removes residual cresidine from impure p-cresidine sulfonic acid, which can contain cresidine in concentrations ranging from above two parts per billion to about 1500 parts per million. The process involves contacting an aqueous solution of p-cresidine sulfonic acid with a sufficient quantity of crosslinked lipophilic porous resin, reducing the concentration of p-cresidine to less than 2 parts per billion.
Another significant patent is for a fertilizer product and the process for making and using it. This process focuses on creating a controlled release fertilizer product that contains an increased amount of sustained-release nitrogen. It includes mixing a partly water-soluble thermoplastic binder, urea-formaldehyde condensate, and a pH modifier to achieve a pH range from about 6 to about 12. The resulting shaped fertilizer product maintains approximately the same amount of sustained-release nitrogen as the urea-formaldehyde condensate in the mixture.
