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. 14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article，once mentioned of 14187-32-7, COA of Formula: C20H24O6
The interaction of the crown ether dibenzo-18-crown-6 (DBC) with iodine has been studied in CHCl3 at room temperature. The charge-transfer absorptions, far infrared and thermal measurements of the formed charge-transfer complex were recorded and discussed. The results obtained show the formation of the pentaiodide complex with the general formula [(DBC)]+ I 5-. The pentaiodide ion, I5-, is described as I3-(I2) confirmed by the observation of the characteristic absorptions for I3- ion around 365 and 290 nm. In addition, the far infrared spectrum of the solid complex shows the three vibrations of I3- unit is at 141, 113 and 71 cm-1 assigned to nuas(I-I) and nus(I-I) and delta(I3-), respectively, while the band related to the vibration of I2 unit is observed at 180 cm-1. Vibration analysis of the obtained data shows that the symmetry of I3- unit could be non-linear with C 2v symmetry. The structure of the formed pentaiodide complex was further supported by thermal gravimetric analysis measurements.
