実験手順

160 parts of 2,4-dinitrophenol are suspended in 240 parts of water. Then 0.5 part of lignosulfonate (dispersant) is added to this suspension and the dinitrophenol is comminuted by ultrasonication. A reactor is charged with 210 parts of 14 % hydrochloric acid and the aqueous suspension of finely particulate 2,4-dinitrophenol and 60 parts of chlorine gas are added simultaneously at 0° C. The addition of the suspension of dinitrophenol is made over 120 minutes and the chlorine is simultaneously added over 130 minutes. When the addition of chlorine is complete, the product is isolated by filtration and washed with 250 parts of water, affording 162.4 parts of 2-chloro-4,6-dinitrophenol (corresponding to a yield of c. 83 %).
