Synergistic catalysis is a specialized approach to catalysis whereby at least two different catalysts act on two different substrates simultaneously to allow reaction between the two activated materials. (wikipedia.org)
An example is if one of the catalysts is a Lewis acid and the other is a Lewis base, there is the possibility for formation of a Lewis acid base complex but this can be overcome by carefully choosing the pair. (wikipedia.org)
Through the combination of two transition metal catalysts, synergistic catalysis has been reported to accelerate many chemical transformations, and even to induce high enantioselectivity, which could not be realized by the use individual catalysts. (wikipedia.org)
Besides using two transition metal catalysts, synergistic catalysis can also be carried out by utilizing one transition metal catalyst in combination with an organocatalyst. (wikipedia.org)
An evaluation of the performance of this Brønsted acidic ionic liquid was made through the comparison to other ionic liquid catalysts as well as conventional homogeneous Brønsted acids. (springeropen.com)
Extending the argument to feedstock security as well as mass utilisation, ultimately in most instances traditional mineral acids appear to be the most sensible option for Brønsted acid esterification catalysts. (springeropen.com)
Popular catalysts are the familiar Brønsted acidic mineral acids and Lewis acidic transition metal salts, but supported catalysts (including enzymes) and recyclable heterogeneous solid acids are becoming increasing popular because of the influence of green chemistry [ 1 , 2 ]. (springeropen.com)
Oxidation1
Next, the use of POMs for homogeneous, solution-phase water oxidation is described together with a summary of theoretical studies shedding light on the POM-WOC mechanism. (mdpi.com)
Chemical transformations1
Ionic liquids have found uses in many applications, one of which is the joint solvation and catalysis of chemical transformations. (springeropen.com)

Reaction4
A polyprotic acid loses each of its protons sequentially, and each reaction has its own K a . (jove.com)
The pH of a polyprotic acid can be estimated using only the first reaction if K a1 is at least one thousand times larger than its subsequent K a 's. (jove.com)
The K a1 for this reaction is 8 × 10 −5 , and it is equal to the concentration of hydronium times the concentration of ascorbate monoanion, divided by the concentration of ascorbic acid. (jove.com)
Acids are classified by the number of protons per molecule that they can give up in a reaction. (jove.com)
Water2
When dissolved in water, ascorbic acid dissociates into hydronium and ascorbate ions. (jove.com)
Fischer esterification combines a carboxylic acid and an alcohol to produce the desired ester, and water as the only by-product. (springeropen.com)
