Participants

Reaction Steps

Starting from 2,6-dichlorobenzaldehyde 75 g (0.43 mol) of 2,6-dichlorobenzaldehyde were dissolved in 400 ml of toluene and then 155 g (0.24 mol) of 25% strength hydroxylammonium sulfate solution were added. At 75° C., 38 g of 50% strength NaOH were added dropwise. After stirring for half an hour, the phases were separated at 75° C., and the organic phase was washed with water and then cooled. At 25° C., 276 g (0.46 mol) of 12.5% strength sodium hypochlorite solution were added dropwise over 4-6 h while simultaneously passing in ethylene. After addition of the hypochlorite solution was complete, the mixture was stirred for 1 h, the phases were separated, the organic phase was washed with water, and the solvent was distilled off under reduced pressure. 82 g (89% of theory) of the required product were obtained with a purity (by GC) of 96%.
