A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Computed Properties of C12H28BrN, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1941-30-6, Name is Tetrapropylammonium bromide, molecular formula is C12H28BrN. In a Article, authors is Abdalla, Amr，once mentioned of 1941-30-6
Surface modification of ZSM-5 catalyst was carried out by silica deposition using chemical liquid deposition (CLD) method as well as core-shell silicalite composite material by hydrothermal method. The modified ZSM-5 catalyst was characterized using various physiochemical methods such as XRD, TPD, N2adsorption-desorption and SEM analysis. Catalytic cracking of 1-butene was carried out using modified ZSM-5 catalysts. The propylene yield was higher for core-shell silicalite composite as compared to silica deposition through CLD method. Silica deposited using CLD method showed propylene-to-ethylene (P/E) ratio of 1.7, whereas core-shell silicalite composite resulted in P/E ratio of 3.0. The higher selectivity to light olefins using core-shell silicalite composite to be attributed to weak acid sites and effective control of external acid sites, which reduces the hydrogen transfer reactions that form alkanes and aromatics. The effective external surface passivation was verified using catalytic cracking of triisopropyl benzene. The core-shell silicalite composite showed excellent stability over 50 h for the cracking of 1-butene stream.
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 1941-30-6, help many people in the next few years.Computed Properties of C12H28BrN
