DETERMINATION OF RESIDUAL SOLVENTS IN LACTIDE AFTER ITS RECRYSTALLIZATION

This article describes a method for the determination of residual solvents in lactide af-ter its recrystallization using gas chromatography-mass spectrometry. The developed method is simple and linear. Study of specificity, accuracy, repeatability and reproducibility showed that the method is suitable for solving presumed problems. It allows identifying and quantify-ing the sufficiently small content (from 72 µg/ml) of solvents in lactide.

Key words: lactide, lactide recrystallization, GC-MS
