ABSTRACT:
The present invention discloses a process for producing a raw material pitch for carbon materials containing a slight amount of ash, the comprising steps of adding aluminum chloride to naphthalene or its derivative as a catalyst; polymerizing said naphthalene or its derivative at a temperature of 100.degree. to 330.degree. C., adding water to the polymer, under stirring if necessary; maintaining the mixture in an emulsified state for a predetermined time under stirring, breaking an emulsion, removing a water layer from the polymer.
