Abstract

Coke plant tar is oxidized at 220°C in air current at 1.8 L/min for 4.5 h. In this process, elemental sulfur is added in quantities of 20, 30, and 40 wt %. With increase from 20 to 40 wt %, penetration declines from 55 to 38 mm; and the softening temperature (determined by the ring and rod method) declines from 52 to 45°C. The change in the physicomechanical properties of the mixture when adding 20, 30, and 40 wt % S is studied by X-ray phase analysis. With 30 wt % S, the reaction of sulfur with the aromatic rings forms 2-naphthanol-6-sulfonic acid (OHС₁₀Н₆SO₃H).

元素硫对公路铺面材料生产的影响

焦化厂焦油在 220°C、1.8 升/分钟的气流中氧化 4.5 小时。在此过程中，元素硫的添加量分别为 20、30 和 40 wt%。随着添加量从 20 wt % 增加到 40 wt %，渗透率从 55 mm 下降到 38 mm；软化温度（通过环棒法测定）从 52°C 下降到 45°C。通过 X 射线相分析法研究了添加 20、30 和 40 wt % S 时混合物物理机械性能的变化。当 S 的重量百分比为 30 时，硫与芳香环反应生成 2-萘酚-6-磺酸（OHС10Н6SO3H）。
