A process for producing a homogeneous, optically anisotropic carbonaceous pitch useful for the production of carbon materials, comprises the steps of thermally cracking and polycondensing a starting oil obtained from petroleum or coal, said starting oil comprising a substantially chloroform-insoluble matter-free oily ortarry substance mcluding a mixture of compounds consisting mainly of carbon and hydrogen having a boiling point of main components in the approximate range 250 to 540°C and containing n-heptane-soluble aromatic oil and resin as the main components, each of which has an aromatic carbon fraction of at least 0.6, preferably at least 0.7, a number-average molecular weight of up to 1000 and a maximum molecular weight of up to 2000.
一种用于生产碳材料的均质光学各向异性碳质沥青的生产工艺,包括对从石油或煤中获得的起始油进行热裂解和缩聚的步骤、所述起始油包括基本上不溶于氯仿的无物质油状或泥状物质,其中包括主要由碳和氢组成的化合物混合物,其主要成分的沸点范围约为 250 至 540°C,并含有作为主要成分的正庚烷溶性芳香油和树脂,每种芳香油和树脂的芳香碳含量至少为 0.6,最好至少为 0.7,平均分子量最高为 1000,最大分子量最高为 2000。
