Procedure

A mixture of water and 2,4-dinitrochlorobenzene is heated to boil. An aqueous sodium hydroxide solution is added dropwise thereto and the mixture is stirred under heating to boil for 1 h to form 2,4-dinitrophenol. Then sodium polysulfide is added dropwise thereto over a period of 3 to 4 h while maintaining a boiling state to promote vulcanization for 24 h under exiling water.
