摘要
采用不同种催化剂合成了丙交酯,以红外光谱,1H-NMR对其进行了表征,并检验了其纯度.结果表明,Zn及其化合物催化效果较好,是制备丙交酯的良好催化剂;所得丙交酯适合制备高分子量聚乳酸.
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.
