USE OF FORMALDEHYDE IN THE POTENTIOMETRIC DETERMINATION OF ORGANIC CARBONYL-COMPOUNDS

The possibility of using formaldehyde as an analytical reagent in orga nic functional analysis is studied. It is shown that an alcoholic solu tion of formaldehyde obtained by the decomposition of paraform is stab le for a long time and can be used for analytical purposes. A new vari ant of the determination of organic carbonyl compounds by oximation is suggested. It is based on the potentiometric titration of the unreact ed hydroxylamine with a solution of formaldehyde in isopropanol using a Pt indicator electrode.
