- 中文摘要: Pure furural, or furfural obtained from pentose by sulfuric acid catalyzed distillation was found to react with anthrone reagent at 0℃. The resulting reaction mixture acquired the characteristic color sufficiently permanent to permit colorimetric determinations. This two-step anthrone reaction was found to be suited for the estimation of pentose fairly contaminated with hexose. Pure pentose samples were determined successfully by the ferric chloride sensitized one-step method. The role of ferric chloride in the anthrone reaction of pentose was studied and discussed.
