Abstract:
A convenient chemical method for determination of electrolyte of glyoxal was reported. The electrolyte contains four components: glyoxal, glyoxalic acid, oxalic acid and hydrochloric acid. The concentration of glyoxal can be determined by the Cannizzaro reaction; oxalic acid can be separated by precipitation, and the dissolved precipitate was titrated by potassium permanganate; the concentration of glyoxalic acid can be determined by the volumetric method of sodium sulfite; hydrochloric acid can be determined by the total acid minus oxalic acid and glyoxalic acid.
