Synthesis of 2,4-dinitrophenol

Preparation of 2,4-dinitrophenol

Preparation of 2,4-dinitrophenol

Preparation of 2,4-dinitrophenol

20 g of 2,4-dinitrochlorobenzene are refluxed for 24 hours with 21 g  of anhydrous sodium carbonate dissolved in 225 ml of distilled water until oil disappears and complete solution is obtained. After cooling, the solution is acidified with hydrochloric acid and the precipitated 2,4-dinitrophenol collected, washed with cold water, and dried yielding 90 % with melting point 114° C. 2,4-dinitrophenol crystallizes from water in pale yellow tables.
