Properties and stability

Irritant to eyes, respiratory system and skin.

Storage method

This product should be sealed and stored in a cool place.

Synthesis method

Obtained from the reaction of phenol and dibromoethane. Stir and mix phenol, dibromoethane and sodium hydroxide in a reaction pot, react at 110°C for 6 hours, recover dibromoethane, the recovery amount is about 60%, wash with 5% sodium hydroxide solution and water, and separate Take the oil layer, distill it under reduced pressure, and collect the 130-150°C (6.7kPa) fraction to obtain (2-bromoethoxy)benzene.

Purpose

Used in organic synthesis.
