The low-boiling paraffinic solvents n-hexane and n-heptane are obtained from dearomatized catalytic reformer naphthas (raffinates) by fractionation and subsequent treatment to bring the content of unsaturated hydrocarbons down to the levels required for use in high-density polyethylene production, in the food industry, or in light industry. Proposes the natural adsorbent A-4M for use in treating paraffinic solvents. Compares 2 variants of the production of paraffinic solvents from catalytic reformer naphtha raffinate: variant I consists of treatment of the naphtha on the A-4M adsorbent, followed by fractionation; variant II consists of fractionation followed by treatment of the hexane (65-70 C) and heptane (92-100 C) cuts on the A-4M adsorbent. Finds that the treatment of the reformer raffinates on the A-4M adsorbent provides removal of the unsaturated hydrocarbons and the production of hexane and heptane solvents of the required quality. Recommends that in producing high-quality paraffinic solvents, it is more desirable to treat the hexane and heptane cuts separately than to treat the original catalytic reformer naphtha raffinate.
