1-Chloro-2,4-Dinitrobenzene → 2,4-Dinitrophenetole

Participants

Reaction Steps

To an equimolar amount of chloro-2,4-dinitrobenzene acid is added sodium ethoxide in ethanol to yield 2,4-dinitrophenyl ethyl ether. Next, to a weighed aliquot of poly (glycidol) containing 0.2 mole polymer in 300 ml of ethanol is added 0.2 mole 2,4-dinitrophenyl ethyl ether, and the reactants heated to reflux and maintained at reflux reaction conditions for 1 to 2 hours. Then dry benzene is added and distillation initiated and continued until nearly all ethanol and water are azeotropically removed, to form the product identified as (I) where n is greater than 10. ##STR34##
