摘要: 以水杨酸和不同链长的烯烃为原料,经过烷基化和钙化工艺,合成了不同烷基结构的烷基水杨酸钙,对其进行红外光谱分析和质谱分析,并对其高温清净性、抗氧化性、油泥分散性、抗泡沫性、分水性和胶体稳定性等进行评价,研究不同结构烷基水杨酸钙产品的性能差别及变化规律。结果表明:随着烷基碳数变化,烷基水杨酸钙的高温清净性、抗氧化性、油泥分散性、抗泡沫性、分水性和胶体稳定性等均存在差异;在烷基碳数为12~18时,烷基水杨酸钙具有较好的高温清净性、抗氧化性、油泥分散性和胶体稳定性;在烷基碳数为20~22时,烷基水杨酸钙具有较好的抗泡性和分水性。

Abstract: Using olefins with different chain length and salicylic acid as raw materials, calcium salicylates with different alkyl structure were synthesized by alkylation and calcification. The performance differences of the products in high temperature detergency, oxidation resistance, sludge dispersion properties, anti-foam property, anti-emulsification property and colloid stability were investigated. The results show that the change of alkyl carbon number of the calcium alkyl salicylate is the main reason for performance differences. The calcium alkyl salicylates with alkyl carbon number of 12 to 18 possess better high temperature detergent resistance, oxidation resistance, sludge dispersion property and colloid stability. When the alkyl carbon number is 20-22, the calcium alkyl salicylates have better resistance to foaming and anti-emulsifying abilityies.
