Abstract

In this study, the petroleum sulfonate(PS) was synthesized from pyolyzed fuel oil by sulfonation reaction with sulfuric acid. The PS synthesized had surfactant behaviors relating to the interfacial properties such as surface tension, surface adsorption, and wetting, etc. These interfacial properties were affected by the sulfonation ratio in the synthesis. As the sulfonation ratio increased, the surface tension of the PS aqueous solution decreased. However, when the ratio was too high, the surface tension was increased due to the extremely higher value of hydrophilicity of PS. At the optimum sulfonation ratio, the PS had a good wettability on the cement particles and a good fluidity of the cement mortar with a high adsorption.

본 연구에서는 정유회사 등에서 폐기되는 부생유(pyolyzed fuel oil)를 황산화 반응하여 petroleum sulfonate(PS)를 합성하였다. 합성된 PS는 계면활성 성질을 나타내었으며 이는 황산화율과 관계가 있었다. 또한 반응에 있어서 황산화율은 온도 및 시간에 따라 속도에 차이는 있었으나 대부분의 경우 40~50% 정도에서 황산화율이 거의 포화에 이르렀다. 황산화율이 증가함에 따라서 친수성이 증가하여 용액의 표면장력이 낮아졌으나 과도한 황산화율에서는 친수성이 너무 강하여 표면장력 값이 오히려 증가하였다. 황산화율에 따라서 적정한 친수-친유 비율에서는 낮은 표면장력과 시멘트에 대하여 우수한 젖음성을 나타내었다. 황산화율에 따라서 PS는 시멘트 표면에 대한 흡착량에 차이를 보였으며 흡착량이 클수록 시멘트에 대한 젖음성이 증가하여 시멘트 입자의 제타전위를 높였으며 보다 우수한 시멘트 몰타르 유동성을 나타내었다.
