Werkwijze voor de winning van benzylbenzoaat

High-purity benzyl benzoate is recovered by distilling the residue remaining after removal of unreacted toluene and benzoic acid from a reaction mixture produced by the oxidation of toluene by molecular oxygen in the presence of a metal catalyst thereby separating a fraction of benzyl benzoate conta...

description High-purity benzyl benzoate is recovered by distilling the residue remaining after removal of unreacted toluene and benzoic acid from a reaction mixture produced by the oxidation of toluene by molecular oxygen in the presence of a metal catalyst thereby separating a fraction of benzyl benzoate containing 80 wt % or more benzyl benzoate, 10 wt % or less benzoic acid and 10 wt % or less fluorenone, and purifying the fraction of benzyl benzoate by crystallization such as recrystallization. According to this process, it is possible to recover high-purity benzyl benzoate by a simple operation at low cost from the by-product formed in the manufacture of benzoic acid.
