红外光谱法研究混酸PEG酯的合成过程

Research of synthesis of PEG mixed acid ester by IR

用大豆油脚水解制得的脂肪酸与聚乙二醇合成了混酸聚乙二醇酯,采用红外光谱法对原料混酸、PEG及产物混酸PEG酯进行分析测试,通过红外谱图的分析与比较,确定了最佳工艺路线及合成条件。

PEG mixed acid ester was synthesized by PEG and fatty acid from soybean oil. The mixed acid. PEG and ester were determinated by IR. The best process engineering and synthetic condition were gotten from comparative analysis of IR spectrums.
