PURPOSE:To obtain pitch suitable as binder pitch, impregnation pitch, etc. for the production of carbonaceous materials such as steelmaking graphite electrodes or aluminum-refining electrodes, by admixing coal tar pitch with specific aromatic compound(s). CONSTITUTION:The objective pitch of low viscosity with high carbonization rate can be obtained by admixing coal tar pitch with at least one kind of 2-4 cyclic aromatic compound having such substituted as to easy to eliminate, e.g. halogen group, alkoxy group, nitroso group, phosphite group, sulfonic acid group (e.g., based on naphthalene, anthracene, phenanthrene, pyrene).
