Principle

Bromine is polarised and, thereby, activated by zinc chloride as a Lewis acid. It can attach itself in an ionic manner to the toluene nucleus via several complex intermediate stages. Following a dehydrobromination, bromotoluene is formed, i.e. the product of bromination in the nucleus.
In the absence of a catalyst and under the influence of light, however, side-chain bromination takes place via radical intermediate stages. The reaction can be controlled in a targeted manner by varying the reaction conditions.

Benefits

  • Secure connection of the items by GL screw joint system
  • Stable and safe setup due to solid stand material

Tasks

  1. Brominate toluene using bromine.
  2. Change the reaction conditions to optimize your results.
  3. Distillate the resulting mixture.
