Abstract The extraction technology has been used to separate furfural produced from straw with the improved sulfuric acid catalytic method.The extractive effect and physical character of different organic solvents have been compared.From the operational lines we will know that the order of extractive rate is:trichlormethane>1,2 dichloroethane>trichloroethylene>dichloromethane>ethyl acetate>carbon tetrachloride.It has selected the extracting flow and equipment of three grades alternate flow.
