Synthetic and analytical studies on colour reagents-X Colour reagents for lithium.
Few colour reagents are known for lithium. Of several hundreds of reagents synthesised by the authors and their collaborators, o,ot-dihydroxyazo compounds were found to be the best, especially those with beta-naphthol derivatives as a coupling component. The bluish colour of the reagent turns to red in the presence of lithium.
