The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article，once mentioned of 14187-32-7, Safety of Dibenzo-18-crown-6
Dibenzo-18-crown-6(DB18C6) is used for the liquid-liquid extraction and membrane transporation of vanadium(V). Vanadium is extracted with DB18C6 in 3.0 M HCI medium using dichloromethane as solvent which forms a colourless complex (lambdamax 285 nm). The complex obeys Beer’s law in the range of 4.25-93.5 ng mL-1. The dichloromethane extract is directly inserted into plasma for inductively coupled plasma atomic emission spectrophotometric (ICP-AES) estimation of vanadium, which enhances the sensitivity several folds and the limits for estimation is 0.2-5.0 ng mL-1 with detection limit 0.05 ng mL-1. The overall formation constant (logbeta2K?e) and extraction constant (Kex) calculated at are 22.20 and 1.8X10-14 at 25C, respectively. Vanadium is preconcentrated and determined in sea water, standard samples and environmental samples.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 14187-32-7 is helpful to your research., Safety of Dibenzo-18-crown-6
