Products of solvent refining of vacuum fractions from hydrodesulfurization of vacuum residue as plasticizers

摘要

Vacuum fractions from hydrodesulfurization of vacuum residue were single and 2-stage refined with furfural,N-methyl-2-pyrrolidone and Me2SO to remove polycyclic arom.hydrocarbons.The exts.and raffi-nates were studied for d.,kinematic viscosity,flow point and group compn.The raffinates were proposed as plasticizers for polymers.The studies are continued.
