Abstract: [Objective]:To identify appropriate methods for extraction of straw cellulose.[Methods]:Respectively use sodium hydroxide-acetic acid-sodium chlorite-acetone method, high pressure cooking method, nitric acid-sodium hydroxide method, sodium hydroxide -sodium hydroxide method, nitric acid-ethanol method and peroxy acids system method to extract corn straw cellulose, using heavy chromium acid potassium-ferrous sulfate ammonium method to determine the content of cellulose, with regarding cellulose content and needed time as evaluating standards, to elect the best technology for extraction corn straw. [Conclusions]: High pressure steaming and nitric acid-alcohol method are superior, for they are simply operated, and has a high speed and high yield advantage. High pressure cooking method for the extraction of cellulose has large output and is suitable for industrial production needs,while nitric acid-ethanol method has small production , but its content is high,so it applies to research institutes and relevant departments.
