iajs-1960	Fahmi Abbas, Ruba	Two Derivative Spectrophotometric Methods for the Simultaneous Determination of 4-AminoAntipyrine in Presence of Its Acidic Products	2018	11	.pdf	application/pdf	3333	178	57	The estimation of binary mixture 4-aminoantipyrine and its acidic product was achieved by first derivative and second derivative spectrophotometric methods by applying zero-crossing at (valley 255.9nm and 234.5nm) for 4-aminoantipyrine and (peak 243.3 nm and 227.3nm) for acidic product. a. Preparation of acidic product for IR- spectral 0.01 gm of pure 4-Aminoantipyrine was refluxed with 100 ml 2N HCl for 60 min. after cooling, the solution was evaporated to dryness by using oven at 700C, the residue was extracted with ethanol, filtered and then dried in air.	cache/iajs-1960.pdf	txt/iajs-1960.txt
