Abstract Zine(II) forms highly fluorescent chelates with the aroyl hydrazones of furfural and 5-hydroxymethylfurfural, with the latter being more fluorescent than the former. The choice of aromatic acid hydrazide (aroyl hydrazine) as analytical reagents for furfurals was examined; 4-toluenesulfonic acid hydrazine was the most sensitive reagent examined, giving a uv fluorescence 10 times as sensitive as 4-hydroxygenzoic acid hydrazide (PAHBAH). More convenient visible fluorescence was given by… CONTINUE READING
