Micro-determination of pyrrole derivatives with N-bromosuccinimide in acetic acid medium
Abstract
A simple micro-procedure for the determination of pyrrole derivatives with N-bromosuccinimide is described. A 2–10-mg sample dissolved in acetic acid is subjected to reaction with a known excess of N-bromosuccinimide at room temperature and the excess of reagent is back-titrated iodimetrically. The maximum error in the results is ±1.44%.
