CARBONYLATION OF TOLUENE
The carbonylation reaction of toluene with carbon monoxide in the presence of HF/BF3 catalyst produces p-tolualdehyde. A high yield results (96% based on toluene and 98% based on CO). p-Tolualdehyde could be further oxidized to terephthalic acid, an important monomer for polyesters:
p-Tolualdehyde is also an intermediate in the synthesis of perfumes, dyes and pharmaceuticals.
