Abstract
A kinetic study based on spectrophotometric and titrimetric techniques has been carried out for the formation of Rubazoic acid type derivative from 4-amino-1(4-sulphophenyl) 3-methyl-2-pyrazolin-5-one (4-amino SPMP). Physico-chemical factors like effect of Time, pH, aeration and temperature on the formation of Rubazoic acid derivative have been studied in detail. The oxidizing and diazotizing property of nitrous acid has been evaluated for 4-amino-SPMP. Moreover the diazonium compound of SPMP was isolated and its stability in solid form has also been investigated.
