Abstract
Dispersants were prepared from petroleum pyrolysis residual oil (PPRO) through sulfonation. Without employing a conventional polynaphthalene sulfonate formaldehyde condensate (PNS) process, the dispersants (NPS) were synthesized by a simpler process only in 2 h. The chemical structure of new dispersant, which has various naphthalene derivative groups, was similar to PNS conformed by UV-visible spectroscopy curves. The new dispersants demonstrated high dispersing ability in inorganic suspension ; cement, $Fe_2O_3$, and $CaCO_3$.
