Substance Name: Syntower bottoms
RN: 64741-62-4

Notes

  • A complex combination of hydrocarbons produced as the residual fraction from distillation of the products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly greater than C20 and boiling above approximately 350 degrees C (662 degrees F). This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.
  • Contains about 58% 3-to 5-ring polycyclic aromatic hydrocarbons and 8-10% carbazole derivatives; skin administration produces toxic changes in liver, thymus and bone marrow in rats.
  • TSCA Definition 2018: A complex combination of hydrocarbons produced as the residual fraction from distillation of the products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly greater than C20 and boiling above approximately 350.degree.C (662.degree.F). This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.
