丙酮在以四乙基铵盐为支持电解质溶液中,当外加电位高至-2.4伏(对饱和甘汞电极)时才在滴汞电极上还原,而且得到的波很不稳定,因此近年来多用间接法测定。即将丙酮与一些试剂作用生成能在较低电位下在滴汞电极上还原的产物,从而测定丙酮含量。Lupton等利用羰基化合物和肼作用生成腙来测定醛和酮。所用支持电解质为酸性硫酸肼。zuman等用伯胺或氨基酸与丙酮作用而测定其产物。新近Hall和van Acetone in the tetraethylammonium salt as a supporting electrolyte solution, when the applied potential up to -2.4 volts (for saturated calomel electrode) was only reduced mercury drop electrode, and the resulting wave is very unstable, so in recent years, multi-purpose Indirect determination. Acetone was reacted with some reagents to produce a product that could be reduced at the drop mercury electrode at a lower potential to measure the acetone content. Lupton and other carbonyl compounds and the use of hydrazine generated hydrazone to determine aldehydes and ketones. The supporting electrolyte used is acidic hydrazine sulfate. zuman and other primary amine or amino acid with acetone and their products were measured. Newly Hall and van
