Abstract
PURPOSE: To easily make a molded pitch product infusible at a low temp. in a short time, by extracting a viscosity adjuster with a solvent in the presence of an aqueous soln. of an oxidizing agent, after pitch, a carbonized particle and the vis- cosity adjuster are mixdd, molten and molded.
CONSTITUTION: After a mixt. consisting of 30W95wt% petroleum or coal pitch and 5W70wt% carbonized particle is mixed with a viscosity adjuster, and the resulting mixt. is molten and molded, the viscosity adjuster is extracted with an org. solvent and removed from the molded product obtd. Then the molded pitch product obtd. is made infusible by thermal treatment in the presence of 0.2W100pts.wt., based on the wt. of the molded product, aqueous soln. contg. 5W90% oxidizing agent. For example, an acid having oxidative power such as nitric acid, sulfuric acid, persulfuric acid or peracetic acid, or an acid soln. of a salt having oxidative power such as a permanganate or a dichromate, is used as said aqueous soln. of the oxidizing agent.
