| Abstract: | Lactide was synthesized by the different catalysts, and the product was characterized by IR and~( 1)H-NMR spectra, the degree of purity was checked as well. The results showed that the catalysts of zinc and its compounds were better than other catalysts tried, and the lactide was suitable for preparation of high molecular weight polylactic acid. |
