Latest Patents
One of Grabowsky's latest patents focuses on the manufacture of formaldehyde. This process involves the oxidative dehydrogenation of methanol in the presence of a silver catalyst. The methanol used is derived from a condensate obtained through the evaporation of aqueous reaction mixtures in the synthesis of urea resins. The process is further refined by treating the condensate with caustic soda under specific conditions of temperature, pressure, residence time, and initial formaldehyde concentration. The formaldehyde produced serves multiple purposes, including being a disinfectant, tanning agent, reducing agent, and a starting material for synthetic resins, adhesives, and plastics.
Another significant patent by Grabowsky is related to the method of cold adhesion of wood glues to wood particles. This innovation improves the cold adhesion of glue resins, particularly phenoplast and aminoplast wood glues, by incorporating small amounts of ligninsulfonate. This enhancement has practical implications for the woodworking and furniture industries.
