Yield:-

Reaction Conditions:

with chlorine;potassium hydroxide in water at 15 - 20; for 6.6 h;Reagent/catalyst;Temperature;

Steps:

1-4 Example 3
In a 5-liter reaction kettle with mechanical agitation (external tail gas absorption device), put 231 grams of monochloroacetone, 275 grams of potassium hydroxide, and 950 grams of water in sequence, control the temperature at 15 to 20 degrees Celsius, and pass chlorine gas under stirring at about 6.6 Hours (calculated according to the flowmeter about 400 grams), the solution system becomes clear, let stand for 1 hour, liquid separation, the resulting lower yellow-green organic phase liquid is dried with 200 grams of anhydrous sodium sulfate,Obtained product 1,1,1-trichloroacetone 301 g; gas phase purity 85%, moisture <0.1%.
