C., on the Atlantic Ocean, a big plant extracts bromine from the sea, manufactures ethylene dibromide for use in antiknock gasolines.

With knocking gasoline, the instant the spark starts ignition, the first burned fuel creates sufficient heat and pressure to ignite all the remaining fuel in one sharp blast, before the spark flame can do its comparatively slow duty. Antiknock compounds obviate the blast, enable the fuel to burn with proper slowness. An observation: gasoline knocks occur after ignition, not before as had been generally supposed...
