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, COA of Formula: C20H24O6
4?,4? (5?)-Di-tert-butyldibenzo-18-crown-6 (DTBB18C6) was synthesized by improving the electrophilic aromatic substitution of dibenzo-18-crown-6 (DB18C6) using tert-butyl alcohol (TBA) as alkylation reagent, H3PO4 (85 wt%) as catalyst and CH 2Cl2 as solvent. Experimental results show that the optimized reaction conditions were 0.03 mol L-1 for TBA concentration, 2.5 for TBA/DB18C6 molar ratio, 0.006 mol L-1 for H3PO4 concentration, 50 C reaction temperature, and 6 h reaction time. Under the optimum reaction conditions, DTBB18C6 yield can reach 43.65%.
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., COA of Formula: C20H24O6
