How do you make dibromoethane?
Preparation and use. It is produced by the reaction of ethylene with bromine, in a classic halogen addition reaction: Historically, 1,2-dibromoethane was used as a component in anti-knock additives in leaded fuels. It reacts with lead residues to generate volatile lead bromides, thereby preventing fouling of the engine with lead deposits.
