Reaction Steps

384 g of 2,4-dichloronitrobenzene, 600 g of tetramethylene sulfone (sulfolane) and 1 g of the emulsifier as specified in Example 1 are introduced into the reaction vessel. Within 4 hours 448 g of 50% potassium hydroxide solution are added at 110° C. After stirring for a further 21 hours at 110° C., the reaction product is adjusted to pH 5.5 to 6 with 240 g of 30% hydrochloric acid and worked up as described in Example 1. 263 g of 5-chloro-2-nitrophenol (76% of the theory) are obtained.
