摘要
重点研究了利用~(19)F-NMR法测定聚醚多元醇中伯羟基的含量前酰化处理过程溶剂、酰化剂加入量、酰化反应时间等实验条件的选择,以及19F-NMR法准确度和精密度的评定。
Primary hydroxyl relative content of polyether polyol was determined by ~(19)F-NMR method,and experimental conditions containing the solvent,the amount of acylating agent added and the acylation reaction time.Furthermore,accuracy and precision of ~(19)F-NMR method were provided by this paper.
