| titleOfInvention | Primary alkyl bromides and chlorides from alpha-olefins |
| abstract | Primary alkyl bromides are prepared by selectively hydrobrominating a C6- 20 a -olefinic hydrocarbon with HBr in the presence of HCl at 0-100 DEG C. under anhydrous conditions, the reaction being initiated by free-radical catalysis. The primary alkyl bromides may be converted to the corresponding alky chlorides by passing dry HCl gas at 130-300 DEG C. into a solution of the alkyl bromide and lithium chloride or bromide or a quaternary ammonium chloride or bromide in an organic acid of the formula RCOOH, wherein R is an inert hydrocarbon radical containing less than 21 carbon atoms optionally having one or more hydrogen atoms replaced by F, Cl or Br. In the hydrobromination of dodecene-1 followed by reaction with HCl, the product contains dodecyl bromide and chloride, plus 1,12-dibromo-, 1,12-dichloro- and 1 - chloro - 12 - bromo - undecane resulting from 1,11-dodecadiene impurity in the dodecene feed. |
