How is 1-Chloro-2-[2-(2-chloroethoxy)ethoxy]ethane (CAS: 112-26-5) typically synthesized?

1-Chloro-2-[2-(2-chloroethoxy)ethoxy]ethane (CAS: 112-26-5) is synthesized via a series of chlorination and etherification reactions. The key steps involve the chlorination of ethylene glycol followed by an etherification reaction to form the desired product. This process typically requires mild to moderate reaction conditions and the use of appropriate catalysts to ensure high selectivity and yield.
