Latest Patents

Schmidt's latest patents focus on a process and catalyst for the orthomethylation of phenols. The first patent describes a catalyst that allows phenols with at least one free ortho position to react with methanol in a molar ratio of about 1:1 to 1:10. This reaction occurs at temperatures ranging from 270°C to 340°C in the gaseous phase, under a pressure of about 1-4 bar absolute, with rates per unit volume of about 0.05-3 h⁻¹, utilizing an iron oxide catalyst. The catalyst consists essentially of iron oxide, molybdenum oxide or tungsten oxide, and one or several oxides of magnesium, calcium, barium, lanthanum, cerium, or manganese in a specific metal-atomic ratio. The second patent outlines a similar process but operates at slightly different temperature conditions, ranging from 250°C to 340°C, while maintaining the same catalyst composition.
