反応手順
The aqueous solution of dimethyldithiophosphoric acid prepared in Example 1 was combined with diethyl maleate (1.33 kg) and hydroquinone (3.3 g), and the resulting two-phase mixture was heated for 8 h at 53-57° C. under nitrogen atmosphere. The two-phase mixture was cooled to 22-30° C., and the phases were separated. The organic phase was washed with water (2×1 kg) to afford crude malathion (1.86 kg) containing at least about 30% (w/w) diethyl fumarate.
