‎First printing. As Frankland discovered ""Combining Power"" (= valency), he had introduced powerfull analytical techniques.""From 1863 to 1870 he and Baldwin Duppa exploited zinc etyl and other organic reagents, including ethyl acetate, in the synthesis of ethers, dicaarboxylic acids, unsaturated monocarboxylic acids and hydroxy acids. This meticulousw work revealed clearly the structure and relationship of these compounds, and of course its methodology had great bearing on the growth of the chemical industry.""(DSB, V: p. 126).‎
