The chemical method for the measurement of interfacial area in liquid-liquid dispersions was first suggested by Nanda and Sharma (S19). They calculated the effective interfacial area a by sparingly extracting soluble esters of formic acid such as butyl formate, amyl formate, etc., into aqueous solutions of sodium hydroxide. This method has been employed by a number of workers, using esters of formic acid, chloroacetic acid, and oxalic acid, which are sparingly soluble in water (D9, DIO, FI, F2, F3, 04, P8, SI5, S20). Sankholkar and Sharma (S5) employed the extraction of diisobutylene into aqueous sulphuric acid. Sankholkar and Sharma (S6, S7) have also found that the extraction of isoamylene into aqueous solutions of sulphuric acid, and desorption of the same from the loaded acid solutions into inert hydrocarbons such as n-heptane and toluene, can be used for determining the effective interfacial area. Recently, Laddha and Sharma (L2) employed the extraction of pinenes into aqueous sulphuric acid. 

It is also possible to introduce additional functionality into the cK-silyl ester. Thus f-butyl (trimethylsilyl)chloroacetate reacts with carbonyl compounds after ester enolate formation with LDA to form f-butyl Q -chloro-a, 8-unsaturated esters, although the elimination of the silyl moiety may have to be encouraged by the use of thionyl chloride, as it also is with the a-bromo analog. A second silyl group, with its additional bulk, can allow for high stereoselection, although the outcome does depend on the metal counterion used in the enolate. ...
