尤其是用二氯亚砜、浓盐酸等做卤代试剂时，对环境污染更加严重。

Especially, dichlorosulfoxide, concentrated hydrochloric acid and other halogenated reagents have caused severe damage to the environment.

用二氯亚砜将萘普生酰氯化，在氮气保护下与脱镁叶绿酸交联，以硅胶柱层析分离产物。

Naproxin was treated by thionyl chloride, then conjugated to Phaeophorbide under protection of N2. The compound was purified by silica gel column.

评述了氯磺酸法、三氧化硫法、二氧化硫法、联产法等氯化亚砜合成方法及其采用这些合成方法的生产企业情况；

Synthesis methods of thionyl chloride such as HSO 3Cl method, SO 2 method, SO 3 method, co production method and enterprises adopting above methods are evaluated.

And the last example that we're going to talk about is thionyl chloride, so it's s o c l 2. This is another good step forward, because now we actually have four different atoms in our molecule.

我们要讨论的最后一个例子,是氯化亚砜，就是硫，氧，氯，二，这又是一个进步，因为我们的分子中现在有四个不同的原子了。
