Amine functionalized K10 montmorillonite: a solid acid-base catalyst for the Knoevenagel condensation reaction.

Dalton Transactions, 2013
Different amine functionalized K10 montmorillonites were hydrothermally fabricated by a simple method of treatment of the neat clay with different amine solutions and used as heterogeneous catalysts towards the Knoevenagel condensation reaction ...

A new site-isolated acid–base bifunctional metal–organic framework for one-pot tandem reaction

, 2014
A highly porous and stable acid–base bifunctional metal–organic framework, MIL-101–NH2–SO3H, was prepared by direct solvothermal synthesis using two mixed (–NO2, –SO3H) terephthalate linkers followed by post-synthesis reduction to the NH2 form, which ...

Phosphotungstic Acid Immobilized on Amine-Grafted Graphene Oxide as Acid/Base Bifunctional Catalyst for One-Pot Tandem Reaction

, 2014
In this study, phosphotungstic acid immobilized on amine-grafted graphene oxide (GOAP) was prepared successfully by silylanization and electrostatic interaction. The obtained GOAP was characterized by Raman spectroscopy, scanning electron microscopy (SEM)

Weak Acid Ionization Constants and the Determination of Weak Acid–Weak Base Reaction Equilibrium Constants in the General Chemistry Laboratory

, 2013
A laboratory to determine the equilibrium constants of weak acid–weak base reactions is described. The equilibrium constants of component reactions when multiplied together equal the numerical value of the equilibrium constant of the summative reaction ...
