| 摘 要： | 为提高稳定同位素利用率和产物的化学纯度,对DDT的合成方法进行了改进:利用浓硫酸及发烟硫酸混合催化的方法,直接使用水合三氯乙醛为原料,经低温长时间反应,半微量合成纯度高于98%的O,P-DDT。以碳酸钡计,DDT合成收率为17.1%。该方法可用于DDT的稳定同位素标记合成。

| Abstract: | Abstract：In order to improve the stable isotope utilizition and the purity of synthesis product DDT［1,1,1 trichloro 2,2 bis (p chlorophenyl)ethane］, the method of preparation has been improved by using concentrated sulfuric acid and fuming sulfuric acid as mixture catalyst, taking reaction at lower temperature and using chloral hydrate directly without dehydration. The purity of o,p DDT product was higher than 98% by this method, and the yield of DDT was 17.1% based on the amount of BaCO3. This synthesis method can be used for o,p DDT labeling by stable isotope. |
