His work has implications for various industrial applications, particularly in the production of refrigerants and solvents.

Latest Patents

One of his latest patents involves a process for producing difluoromethane. This process includes the step of contacting a gaseous mixture containing CH₂Cl₂ and hydrogen fluoride with a catalyst that contains a catalytically effective amount of trivalent chromium supported on a carbon with an ash content of less than 0.5 percent by weight. The reaction occurs at temperatures ranging from about 180 °C to about 375 °C. The catalyst and temperature conditions allow for the concurrent reaction of CCl₃CF₃ with HF to form CCl₂FCF₃, CH₂ClF, and unreacted CH₂Cl₂, each of which can be recovered as an azeotrope with HF and may be recycled.
