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
