A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 79725-98-7, Name is (4-Oxo-5-(palmitoyloxy)-4H-pyran-2-yl)methyl palmitate, molecular formula is C38H66O6. In an article, author is Wang, Liujiao,once mentioned of 79725-98-7, Formula: C38H66O6.
Covalent cross-linked anion exchange membrane based on poly(biphenyl piperidine) and poly(styrene-b-(ethylene-co-butylene)-b-styrene): preparation and properties
Poly(biphenyl piperidine) and polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene were cross-linked to form a polymer backbone, piperidine as the ionic conducting group to improve the chemical stability of the anion exchange membrane. Results indicate that the cross-linked membranes could still retain more than 95% of ion conductivity after being soaked in 1-M KOH solution at 80 degrees C for 800 h, indicating that this cross-linked membrane exhibits good alkaline stability. The optimized microphase separation morphology could promote the ion transport (81.68 mS/cm, 80 degrees C). The cross-linked structure helped to restrain the swelling behavior. The membrane became flexible after cross-linking, which is beneficial to the fuel-cell assembly.
