The Selection of Solvents for the Recovery of Furfural from an Extract Solution in the Selective Refining of Lubricating Oils,
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)
