“…near room temperature and atmospheric pressure without any expensive reagents [ 120]. Takenaka et al [120][121][122] have studied the feasibility of a commerical electrochemical procedure for m-phenoxy benzyl alcohol (16) which is a useful intermediate for medical and agricultural chemicals, and an important component of the pyrethroid insecticide ethofenprox (17) (TREBON). Due to its excellent pesticidal activity along with its low toxicity to fish and to mammals, there is a wide market for ethofenprox, especially in agricultural pest control.…”

“…The parallel-plate configuration is widely used because of its numerous attractive characteristics. These advantages can be seen from an industrial, research, or practical point of view: wide availability of its components; ease of scale-up , and versatility, which enables the electrolyzers to be used in different configurations for a wide variety of processes; growth in the successful application of pilot- and full-scale electrochemical filter-press reactors; − wide offer of commercial electrochemical filter-press reactors from laboratory to industrial scale; , simplicity of construction; uniform potential distribution; ease of operation and minimal maintenance problems; possibility of electrical monopolar or bipolar connection; , incorporation of three-dimensional electrodes; incorporation of turbulence promoters; and ease of gas removal , and of temperature and flow control…”

This work deals with the study of the influence of turbulence promoters in the hydrodynamic and mass transport behavior of a pilot-plant filter-press electrolyzer (a homemade UA200.08 with a 200 cm 2 electrode area) in an undivided configuration. A simple experimental arrangement was used to generate data from electrolytic conductivity measurements in a series of impulseresponse experiments. The presence and type of turbulence promoters influence the flow distribution inside the reactor. A new design of a model (presented in a previous work) has been used to analyze the residence time distributions. In this study a new parameter, the turbulence factor, given as N R Φ β , was employed to classify the turbulence promoters. The optimization of the parameters indicates that the correct model is dispersed plug-flow behavior with a low axial dispersion that considers exchange between the dead and main zones of the reactor. It is also very interesting to highlight that the information obtained by means of the turbulence factors is similar to that obtained from the values of the mass transport coefficients measured using the limiting current technique.

Electrochemical processes are used to produce an array of reactive inorganic chemicals and metals. The most reactive materials, strongest oxidants, and strongest reductants are produced electrochemically at anodes and cathodes, respectively. Process technology for the production of each electrochemical is unique. Power supplies and electrolytic cells are the distinguishing features of electrochemical processes. Electrolytic cells use direct current and are designed to be process specific. Every cell consists of an anode, a cathode, and container. Cells may be monopolar or bipolar, with or without separators, and equipped to handle aqueous solutions or fused salt electrolytes. Industrial processes described include electrolysis of chloride solutions and production of manganese dioxide, fluorine, permanganate, and hydrogen peroxide. The electrolysis of water and production of heavy water are also described. Processes for electrowinning of metals from aqueous solutions and from fused salts are discussed as are electrochemical processes for hazardous waste treatment systems.
