With a total of 2 patents, Juhl's work has had a notable impact on various industrial applications.

Latest Patents

One of Juhl's latest patents is focused on stable polyamide solutions. This innovation involves stabilizing polyamide solutions for imparting wet strength to paper by acidifying uncrosslinked polyamide solutions prior to storage or crosslinking with epichlorohydrin. This method allows for storage without refrigeration and results in wet strength resins that are stable at solids concentrations of at least 30%. These resins exhibit high strength when post-cooked to a viscosity between about 325 and 425 cps.

Another significant patent by Juhl involves the use of molecular sieves as catalysts for the preparation of 1,1,2-trichloroethane. This process improves upon the chlorination of EDC in a boiling bed by mixing chlorine and dichloroethane in the vapor phase and passing them over a molecular sieve catalyst. This innovative approach enhances the efficiency of producing 1,1,2-trichloroethane.
