Abstract
The present work was focused to throw some light on the electrochemical
reduction of some selected carbonyl compounds, viz,
4-(4-N,N dimethyl aminophenyl)3-butenone (I)
3-(4-N,N dimethylaminophenyl)-1-phenyl-2-propenone (II)
1-(4-chlorophenyl)-3-(4-N,N dimethylaminophenyl)2-propenone (III)
3-(4-N,N dimethylaminophenyl)-2-propenone (IV)
in 1M H2SO4 solution of 20% alcohol – water mixture, at some metallurgical and electrodeposited cathodes, such as metallurgical copper, metallurgical Lead, deposited copper deposited Lead and deposited Lead-copper.
The effect of different factors such as, carbonyl compound concentration, current density and surface texture of deposited cathodes on the reduction efficiency has been investigated.
A new mechanism of alternating current superimposition on direct current of reduction or of cathode deposition or both of them was also studied, The present investigation contains three chapters: -
1- Chapter 1, the theoretical knowledge and the literature survey on the electrochemical reduction of carbonyl compounds, at different cathodes with various surface textures.
2- Chapter 2 includes the experimental part, which contains the molecular structure of the selected carbonyl compounds under investigation, working procedure for measuring the current efficiency of reduction, as well as the apparatus used for bath electrodeposition of metal cathodes and polarization measurements.
3- Chapter 3 includes the results and discussion of the data obtained during the present investigation, regarding the electrochemical reduction of different carbonyl compounds at metallurgical and electrodeposited cathodes.
The reducibility of selected carbonyl compounds depends on many factors. These factors can be classified into three main groups. The first group includes the nature of the medium and conditions of reduction process (solvent nature, concentration, current density and cathodic material). The second group concerns with the structure of the carbonyl compounds. The third involves the cathode material (its nature and microstructure).
