Application in Electrosynthesis

In this work, we present recent results concerning the application of BDD electrodes in the electrooxidation of organic and inorganic compounds, with applications in electrosynthesis and in the destruction of pollutants for wastewater treatment...

Nitrogen heteroaromatics are expected to be useful probases. The cathodic reduction of phenazine, (31), resembles closely that of (29a) [70,71], and the kinetic basicity of (31) is comparable to that of (29a) [54]. However, application of (31) as a PB in electrosynthesis has not been reported, and there is only a single report concerning the use of the radical anion of acridine, (32), as an EGB [72]. 

Principal applications are in electrosynthesis, metal recovery and, sometimes, electroanalysis. 

There is a trend toward chiral synthesis [132] the Englehard company is said to have piloted the electrosynthesis of chiral diols. New reactor design for the epoxidation of olefins is under development on a pilot scale [133]. Gas diffusion electrodes, developed for fuel cells and inorganic processes, are finding their first applications in organic electrosynthesis [134—136]. Another area of more than laboratory interest is bioelectrochemistry [137] (see also E. Steckhan, Chapter 27 in this volume). 

Ultrasound influences multiphase systems such as the production of microemulsions. It is useful in electrosynthesis involving immiscible materials—this effect has been particularly exploited for several applications in environmental science. Ultrasound can also enhance electrochemiluminescence systems, and has been applied to many other aspects of electrochemistry, including the as yet unexplained benefits of pre-treating electrolyte solutions. It has even been proposed to enhance electrochemical cold-fusion . 

The simultaneous application of ultrasonic irradiation to an electrochemical reaction which has been termed sonoelectrochemistry has been shown to produce a variety of benefits in almost any electrochemical process. These include enhanced chemical yield in electrosynthesis and the control of product distribution improved electrochemical efficiency in terms of power consumption, improved mixing, and diffusion in the cell minimization of electrode fouling accelerated degassing and often a reduction in the amount of process-enhancing additives required. In a major chapter devoted to this topic, Suki Phull and Dave Walton have attempted to cover the majority of applications of ultrasound in electrochemistry including electrochemical synthesis, electroanalytical chemistry, battery technology, electrocrystallization, electroinitiated polymerization, and electroplating. 

In the past, many candidate processes failed to yield the required return on investment because reactor designs at the allowable capital investment were not available. In spite of this, applications for electrosynthesis with the required profitability are growing as electrochemical engineering with a "systems" approach develops. To apply some of the newer chemical proposals it will be necessary to develop even more accurate mathematical design models and more innovative three-dimensional low-voltage-drop electrodes.

Faraday s law, as well as its expression as a local vector, will be demonstrated in greater detail later in this book 1 This law has numerous applications, notably in industry. For instance, it forms the basis of the theoretical calculation for battery capacity, for homogeneous corrosion rates of metals, and for the amount of substance produced or consumed in electrosynthesis processes, etc.

Similarly to the assumption for diffusion-based EET, electrons cannot be sent back to the cells. (The microbial respiratory electron transport chain cannot work in reverse.) We believe that this assumption can be modified to model cathodic EABs that oxidize substrates extracellularly and may have applications in high-value chemical production (e.g., via electrosynthesis).
