What is O-Phthalaldehyde Assay Method about?
The invention presents a method for accurately assaying o-phthalaldehyde (OPA) by reacting it with excessive oxammonium hydrochloride and triethanolamine, followed by titration with a 0.1 mol/L sulfuric acid solution. The process involves preparing analytical solutions, conducting a one-hour reaction, and performing a detailed titration to determine OPA content. This method enhances accuracy and simplifies operation compared to prior art techniques.
