3-Phenoxybenzaldehyde → HCID 88794023, compound

Participants

Reaction Steps

To a solution prepared by dissolving 1.3 g of triethylamine hydrochloride (0.009 mole) in 69.2 g of a 35.8% aqueous solution of sodium bisulfite (0.238 mole of sodium bisulfite) while being stirred at room temperature, was added dropwise taking 2 hours a solution prepared by dissolving 50 g of crude 3-phenoxybenzaldehyde (72.5% purity (0.183 mole of 3-phenoxybenzaldehyde) and containing no other aldehyde compounds) in 80 g of toluene. Immediately after the starting of the dropwise addition, white crystals began to precipitate out of the reaction system. After completion of the addition, stirring was continued for a further 2 hours. The crystals were collected by filtration, washed three times with 50 g of toluene, and dried to obtain 54.5 g (98.5% yield) of 3-phenoxybenzaldehyde sodium bisulfite adduct.
