Electrolytic dielectrics include metal oxides, aqueous-based liquid electrolytes, and non-aqueous-based liquid electrolytes. The most commonly used metal oxides are aluminum oxide, tantalum pentoxide, and niobium oxide. A typical aqueous-based liquid electrolyte contains boric acid or sodium borate in aqueous solution with various sugars or ethylene glycol to retard evaporation. Eor example, there are three major types of water-based electrolytes for aluminum electrolytic capacitors standard water-based (with 40% to 70% water), those containing ethylene glycol (with less than 25% water), and dipropyl ketone (with less than 25% water). 

In the course of this study, the authors determined /Lvalues for dibenzyl, methyl phenyl, methyl p-nitrophenyl, di-p-tolyl, di-isopropyl and tetramethylene sulphoxides and for diethyl, dipropyl and dibutyl sulphites. The /Lscales are applied to the various reactions or the spectral measurements. The /Lscales have been divided into either family-dependent (FD) types, which means two or more compounds can share the same /Lscale, family-independent (FI) types. Consequently, a variety of /Lscales are now available for various families of the bases, including 29 aldehydes and ketones, 17 carboxylic amides and ureas, 14 carboxylic acids esters, 4 acyl halides, 5 nitriles, 10 ethers, 16 phosphine oxides, 12 sulphinyl compounds, 15 pyridines and pyrimidines, 16 sp3 hybridized amines and 10 alcohols. The enthalpies of formation of the hydrogen bond of 4-fluorophenol with both sulphoxides and phosphine oxides and related derivatives fit the empirical equation 18, where the standard deviation is y = 0.983. Several averaged scales are shown in Table 1588. 

As mentioned so many times throughout this entire course, there are almost always multiple correct solutions to a synthesis problem. For example, in this case, the desired transformation can be achieved using several reactions from previous chapters. The starting ketone can be converted into an ester via a Baeyer-Villiger oxidation, followed by hydrolysis to give propanoic acid. This acid can then be converted to an acid chloride upon treatment with thionyl chloride, followed by conversion to the product upon treatment with lithium dipropyl cuprate ...
