Abstract : It was established that the recovery of furfural from an extract solution can be carried out with the help of pairs of extractants: light hydrocarbons solvents of the naphtha II type (fraction at 100-120C) or 'galosha' gasoline and ethyl alcohol. In the course of selecting the pairs of extractants, the mutual solubility of hydrocarbons - hexane, heptane, 'galosha' gasoline, naphtha I (fraction at 70-100C), naphtha II (fraction at 100--120C) - with alcohols (methyl, ethyl, isopropyl) was studied. The critical solution points of the listed substances were found. (Author)
