  • Patent number: 10494722
    Abstract: The sulfonamide corrosion inhibitors are compounds of formula A or formula B, as follows: A method of synthesizing the sulfonamide corrosion inhibitors includes functionalizing a polyamine precursor with a sulfonyl chloride derivative by dehydrochlorination. The polyamine precursor may be bis(3-aminopropyl)amine and the sulfonyl chloride derivative may be methanesulfonyl chloride. The sulfonamide corrosion inhibitors may be applied alone or in any combination as corrosion inhibitors of a metal and are shown to be effective inhibitors of corrosion of iron or iron alloys in acidic conditions.

  • Patent number: 10017474
    Abstract: The method of synthesizing (E)-1,2-di(pyridine-2-yl)ethene-1,2-diol involves dimerization of 2-pyridinecarboxaldehyde (also referred to herein as “picolinaldehyde”). The synthesis of the desired ethene-1,2-diol is achieved using a Cu(II) catalyst to dimerize picolinaldehyde under mild conditions. Preferably, the Cu(II) catalyst is a Cu(II)/neocuproine (2,9-dimethyl-1,10-phenanthroline) complex, or other Cu(II)/phen complex. The reaction in this embodiment may occur at room atmosphere and in ambient light conditions using a water/ROH solvent.

  • Patent number: 10016752
    Abstract: The method of making palladium nanoparticles is a microwave thermolysis-based method of making palladium nanoparticles from a complex of palladium(II) acetate Pd(O2CCH3)2 (or Pd(OAc)2) and a ligand. The complex of palladium(II) acetate and the ligand is melted in oleic acid and dichloromethane to form a solution. The ligand is 1-(pyridin-2-yldiazenyl)naphthalen-2-ol (C15H11N3O), which has the structure: The solution is stirred for two hours under an inert argon atmosphere, and then irradiated with microwave radiation to produce palladium nanoparticles.
