The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14098-44-3, Name is Benzo-15-crown-5, molecular formula is C14H20O5. In a Article，once mentioned of 14098-44-3, Safety of Benzo-15-crown-5
Phthalocyanines with four 15-crown-5 ether voids at the 3,4-positions (MtCRPc) (Mt = H2, Zn, Co, Ni, Cu) have been synthesized and characterized.Dimerization of MtCRPc is induced in solvents such as methanol and by addition of some cations (K+, Ca2+, NH4+), especially K+.Cofacial dimer formation in the presence of these cations proceeds in a two-step three-stage process, as indicated by absorption and emission spectroscopy.These species have a highly specific D4h eclipsed configuration providing well-defined dimeric species for spectroscopic analysis.The ESR spectrum of the cation-induced dimeric CuCRPc shows axial symmetry and may be analyzed in terms of an interplanar separation of 4.1 Angstroem.The 1H NMR spectra of the cation-induced metal-free and zinc dimers are consistent with an eclipsed configuration.Upper excited state (Soret, S2) emission is observed for the first time in the phthalocyanine series.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Benzo-15-crown-5, you can also check out more blogs about14098-44-3
