In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: Pd2(DBA)3, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 52409-22-0, name is Pd2(DBA)3. In an article，Which mentioned a new discovery about 52409-22-0
A C12-naphthylamine antioxidant (3,3?-(dodecylazanediyl)bis(N-(4-(naphthalen-2-ylamino)phenyl) propanamide)) was successfully synthesized via Michael addition and amidation reactions. The chemical structure was analyzed by Fourier transform infrared spectra (FTIR), 1H-nuclear magnetic resonance spectroscopy (1H NMR), and liquid chromatography?mass spectrometry (LC?MS). Thermal stability of C12-naphthylamine antioxidant was also examined by differential scanning calorimetry (DSC). The scavenging capacity of antioxidants was investigated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The efficiency of the antioxidants in thermo-oxidative stabilization of polyethylene (PE) was determined by DSC, FTIR, and tensile testing machine. The results showed that the inhibition percentage of the C12-naphthylamine antioxidant was 57.09, the oxidation induction time (OIT) was 157.83 min, and the carbonyl index (CI) was 0.25. In addition, the C12-naphthylamine antioxidant had a better antioxidant efficiency in both scavenging test and thermo-oxidative test compared with N-phenyl-2-naphthylamine and N,N?-di-2-naphthyl-p-phenylenediamine. The result for migration of antioxidants from PE indicated that migration content of C12-naphthylamine antioxidant was small.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 52409-22-0, help many people in the next few years.Recommanded Product: Pd2(DBA)3
