摘要： 采用高效液相色谱法对硫化烷基酚钙中的游离烷基酚进行测定，首先通过甲醇萃取硫化烷基酚钙中的游离烷基酚，再通过高效液相色谱对甲醇提取液中烷基酚进行检测，由此推算出硫化烷基酚钙中游离烷基酚含量。高效液相色谱采用C8色谱柱，流动相水与甲醇的体积比为0.1:0.9，总流速为1 mL/min，紫外检测波长为280 nm，柱温为30 ℃。该方法的加标回收率为97.3%~99.1%，相对标准偏差为0.19%~0.62%，具有操作简便、快捷、准确度高的特点。

Abstract: The free alkylphenol in the sulfurized calcium alkylphenolate were determined first by methanol extraction, followed by high performance liquid chromatography (HPLC) and finally by calculation. The HPLC conditions are: C8 column at 30 ℃, water and methnol as mobile phases with a water/methanol volume ratio of 0.1:0.9, flow rate 1 mL/min, UV detection wavelength of 280 nm. The recovery of this method is 97.37%-99.84 %, and the relative standard deviation is 0.19%-0.62%. The method has the advantages of simple operation, fast and high accuracy.
Key words: free alkylphenol, sulfurized calcium alkyl phenolate, high performance liquid chromatography
