Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene

Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene

Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.

Potentiometry: Membrane Electrodes

Potentiometry: Membrane Electrodes

Membrane electrodes, also known as p-ion electrodes, use membranes that selectively interact with free analyte ions, generating a potential difference across the membrane. The resulting membrane potential, known as the asymmetry potential, is not zero even when analyte concentrations on both sides of the membrane are equal. The membrane's response is typically not selective to a single analyte but proportional to the concentration of all ions in the sample solution capable of interacting at...

Interfacial Electrochemical Methods: Overview

Interfacial Electrochemical Methods: Overview

Interfacial electrochemical methods focus on the phenomena occurring at the boundary between an electrode and a solution, as opposed to bulk methods that concentrate on the solution's overall properties. These interfacial methods are classified as either static or dynamic based on the presence of a nonzero current in the electrochemical cell and the consistency of analyte concentrations. Static methods, such as potentiometry, measure the cell's potential without any significant current...

Extraction: Advanced Methods

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Electron Affinity

Electron Affinity

The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Fluorescence and Phosphorescence: Instrumentation

Fluorescence and Phosphorescence: Instrumentation

Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.

Background:

Fluoride ions are essential components in advanced battery electrolytes, particularly in fluoride shuttle batteries.
The use of organic solvents in these electrolytes necessitates reliable methods for quantifying fluoride ion concentration.
Existing methods for fluoride detection in organic media are often limited or challenging to implement.

Purpose of the Study:

To develop a fluoride ion-selective electrode (ISE) suitable for use in organic solvents.
To establish a method for quantifying fluoride ion concentration in propylene carbonate (PC) solutions.
To investigate the potential of a second-kind electrode for detecting ions in challenging organic environments.

Main Methods:

Fabrication of a silver|silver fluoride (Ag|AgF) electrode via anodization of a silver wire in PC with dissolved fluoride ions.
Electrochemical characterization of the Ag|AgF electrode to assess its response.
Measurement of open circuit potential against logarithm of fluoride ion concentration in PC solutions.

Main Results:

The fabricated Ag|AgF electrode demonstrated a stable, linear response of open circuit potential to the logarithm of fluoride ion concentration.
The linear response was observed over a concentration range of 10^-4 to 10^-2 mol dm^-3 in PC.
