摘要
文章利用近红外光谱法,采用多元线性回归检测了聚醚多元醇的伯羟基与仲羟基的相对含量,得到了较好的预测结果,对工业在线检测具有重要的参考价值。
The method of near infrared spectrum, eombined with derivative spectrum and multiple linear regression was applied to measure the ratio of primary hydroxyl group to second hydroxyl group in polyether polyol. The authors obtained good predictive results by using the method in this experiment. The work is very helpful for the on-line measurement of polyether polyol.
