If we bubble HCl gas through the solution, or add a small quantity of concentrated H2SO4, we get an acid-catalyzed reaction that occurs by a mechanism analogous to that described in the previous section.2 Acid-catalyzed reaction of an alcohol with a carbonyl ϩ OEH B CH3ECHCH3 SOO OH...
The catalytic decarbonylation reaction mechanisms of 2-methyl-2-propenal in the presence of hydrogen chloride (HCl), water (H2O), or sulfuric acid (H2SO4) have been investigated theoretically for the first time. Both concerted and stepwise mechanisms have been considered. Compared with un...
This agrees well with the activation energies calculated in a sepatrate investigation of the decomposition of AHS in the presence of the group IA metal sulfates. A reaction mechanism that involves the formation of ammonium pyrosulfate and triammonium hydrogen sulfate as intermediates, and ammonia, ...

Predict the products from the reaction of 1-hexyne with 2 equiv HCl. Write the plausible reaction mechanism of the following reaction: 1-methyl-1-cyclohexanol + H_2SO_4 with heat to Show the final product for the reaction using H2SO4 and Heat. What products woul...
Reactant models are (A) phthalic anhydride + (phenol)(2)+ H(2)SO(4)and (B) phthalic anhydride + (resorcinol)(2)+ H2SO4, respectively. For (A), the acid catalyzedorthoandparaphenol additions to phthalic anhydride were compared. While theorthoaddition is more favorable than theparaone, ...
The reaction exotherm was combined with the reaction mechanism. Differential scanning calorimetry revealed that the hydrogen peroxide was relatively stable when Na2WO4.2H2O and H2SO4 were used as cocatalysts. Reaction calorimetry, in situ Fourier transform infrared spectroscopy and gas chromatography/mass ...
it's just that the most energetic step is the step with the highest energy transition state is what determines the activation energy? So it's all the steps in between the initial state and the highest energy step. And enzymes always bring the reaction through a different mechanism, i beleiv...
实验结果表明,TiO2光催化降解2,4-DCP效果较好,降解的最佳pH为7,催化剂的最佳投加量为200mg・L-1。2,4-DCP的初始浓度越小,光催化的效率越高。在初始浓度为5mg・L-1时,光催化1h的降解率达90%。在实验的四种不同初始浓度(5mg・L-1、10mg・L-1、20mg・L-1、40mg・L-1)下,2,4-DCP的光降解...
