使用高效液相色谱仪对腰果双酚醚化闭环后制备出产品进行定性定量分析。得到的环氧化腰果酚与醇钠比例为2.5：1精制。使用液相色谱仪在25℃温度下，以甲醇为流动相测精制后E-Cardol的液相色谱图。使用甲醇稀释样品至780倍，测其液相色谱图，确定环氧化腰果酚除氯程度。重复测试。

Qualitative and quantitative analysis of the product prepared by etherification of cashew bisphenol using high-performance liquid chromatography. The obtained epoxidized cashew phenols were refined in a ratio of 2.5:1 to sodium alcohol. Use a liquid chromatograph to measure the liquid chromatogram of refined E-Cardol using methanol as the mobile phase at a temperature of 25 ℃. Dilute the sample with methanol to 780 times and measure its liquid chromatography to determine the degree of chlorine removal by epoxidized cashew phenols. Repeated testing.
