Process for producing n-propyl bromide or other aliphatic bromides

摘要

A process for the production of an aliphatic bromide in which the bromine atom is attached to a terminal carbon atom, which process comprises continuously feeding olefin having a terminal double bond, gaseous hydrogen bromide, and a molecular oxygen-containing gas into a liquid phase reaction medium comprised of aliphatic bromide to cause anti-Markovnikov addition of HBr to terminal olefin, the feeds being proportioned and maintained to provide a molar excess of hydrogen bromide relative to terminal olefin in the range of about 1 to about 5 percent, and a molar ratio of molecular oxygen to terminal olefin of less than 0.005. The process is especially suited for production of n-propyl bromide.
