WebMar 30, 2024 · Orcinol was polymerized in aqueous alkaline solution via phenoxy radicals using NaOCl, H 2 O 2 and air as oxidant at various conditions such as temperature, reaction time and concentration of the initiator. It was observed that the conversion to oligomer varied depending on the conditions and type of the oxidants. WebThe orcinol–sulfuric acid method, in which the recommended reagent is a solution of orcinol (0.1%, m/v) in diluted sulfuric acid (70%, v/v), was the first to be adapted for use in an automated carbohydrate analyzer.
