使用高效液相色谱仪对腰果双酚醚化后制备出产品进行定性定量分析。使用液相色谱仪在25℃温度下，以甲醇为流动相测90℃醚化产物氯醚醇的液相色谱图。使用甲醇稀释样品至780倍，测其液相色谱图，确定腰果双酚醚化程度。

Qualitative and quantitative analysis of the product prepared by etherification of cashew bisphenol using high-performance liquid chromatography. Use a liquid chromatograph to measure the liquid chromatogram of the etherification product chloroetherol at 90 ℃ 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 etherification of cashew bisphenol.
