| 中文摘要 | a new method for quantitative analysis of lactide has been developed by applying chemical kinetics to a hplc system. the most important advance is its practical approach to the quantification of analytes that are unstable in the hplc mobile phase. in hplc analysis, anhydrous mobile phases cannot separate lactide from impurities, and only mixtures of water and organic solvent can achieve effective separation. by selecting conditions for testing and studying the kinetics of lactide hydrolysis, extensive experiments revealed that lactide degradation can be treated as a pseudo-first-order reaction under the given hplc conditions, and lactide content or purity can be quantitatively determined. this method is practical for measuring the purity of the intermediate lactide in polylactic acid (pla) production and the lactide content in pla. |
