Procedure

A mixture of 2-vinylpyridine (650 g) and styrene (350 g) is washed twice with 5% NaOH in water (each 320 mL) and twice with water (each 640 mL) to remove the inhibitors. The monomers which contain some residual water have a volume of 1039 mL and are used in b below.

Workup

  1. washis washed twice with 5% NaOH in water (each 320 mL) and twice with water (each 640 mL)
  2. customto remove the inhibitors
