¹³C₁-DDT的合成及结构表征

摘要: 以氯苯和¹³C-乙醇为主要原料，浓硫酸为催化剂，合成了¹³C₁-DDT，产物经DSC、FT-IR、1H NMR、¹³C NMR、MS分析表征。结果表明，产物化学纯度>99%，同位素丰度>99%，产率为51%。所得产物为目标产物，可用作同位素内标。

Abstract: Chlorobenzene and ¹³C-chloral were used as the raw materials to generate the target product ¹³C₁-DDT in concentrated sulfuric acid as catalyst.The isotope labeled compound was characterized by DSC, FT-IR, 1H NMR, ¹³C NMR and MS. The results showed that the chemical purity of the product was better than 99% and its isotopic abundance was more than 99%. The yield of product was 51%. ¹³C₁-DDT product could be used as standards.
