Synthesis of Luminol Performed 7/15/10 Results: 3-nitrophthalic acid (.607g) was reacted with 10% hydrazine (0.8mL) to form the intermediate product 5-nitrophthalhydrazide. The weight of this product was .56g. The 5-nitrophthalhydrazide was then reacted with 10% sodium hydroxide (2.6mL) and sodium dithionite dehydrate (1.62g) to form the final product luminol. This final step yielded no product after two repeated attempts so the luminol results of a neighbor were used. In his reaction 0.601g 3-nitrophthalic acid were reacted with 0.8mL of 10% hydrazine and the 5-nitrophthalhydrazide product was reacted with 1.01g sodium dithionite dehydrate. His final luminol product weighed .535g giving a percent yield above 100%, indicating a flaw in the collection. No melting point or TLC plates were measured. The luminol product (.027g) was added to a beaker filled with potassium hydroxide pellets and dimethyl sulfoxide where it was observed to glow a faint blue. The dye Eosin was
