Abstract

PURPOSE: The titled raw pitch of low softening temp. capable of easily forming mesophase in the preparation of precursor pitch, which is prepd. by mixing a heavy oil produced as a byproduct in the steam cracking of a petroleum with a nucleus-hydrogenated arom. hydrocarbon and thermally treating the resulting mixt. under specified conditions.
CONSTITUTION: 10W200vol% nucleus-hydrogenated compd. from a di-or tricyclic arom. hydrocarbon such as tetralin or dihydroanthracene is added to 100vol% heavy oil of b.p. ≥200°C produced as a byproduct in the preparation of ethylene, propylene, etc. by the steam cracking of a petroleum such as naphtha at about 700W1,200°C, and the obtd. mixt. is thermally treated at 370W480°C under a pressure of 2W50kg/cm2 for 15minW20hr, to obtain raw pitch for carbon fiber.
