✦ Synopsis
The quantitative and qualitative analysis of acetic, propionic, m-butyric, nvaleric, rt-hexoic, +z-heptoic, a-octoic, ?+nonoic and rt-decanoic acids present in dilute aqueous media as free acids or salts, in the presence of mineral acids or bases, is described. The +bromophenacyl or $-phenylphenacyl esters of the acids were formed and injected into 2.5 o/o sodium dodecylbenzene sulphonate or I o/o Apiezon L or a I : I mixture of the two (depending on which acids were present) coated on acidwashed Go/So mesh Chromosorb G packed in a 6-ft. glass column.
