| Shrnutí: | Title screen L-lactide synthesis from an aqueous solution of L-lactic acid under different conditions in the presence or absence of a catalyst (zinc oxide, stannous octoate or magnesium ethoxide) has been studied. Synthe-sis of L-lactide is accompanied by analytical control. The glass transition temperature of lactic acid oligo-mers, i.e. a product of polycondensation at the first stage of the process, has been investigated using differential scanning calorimetry (DSC). Identification and quantitative determination of lactic acid and L-lactide at different stages of the synthesis have been performed by HPLC. A residual solvent in L-lactide after its recrystallization has been determined by gas chromatographymass spectrometry (GC-MS). Свободный доступ из сети Интернет |
