Hydroquinone → HCID 67706101, compound

Participants

Reaction Steps

About 4.4 g (0.04 mol) hydroquinone and about 11.68 g (0.04 mol) of 1,3-bis(3-aminophenoxy)benzene were dissolved in a mixture of about 65 mL propyl cellosolve (chemical name ethylene glycol monopropyl ether) and about 15 mL of tetrahydrofuran (THF) in a round bottom flask. About 23.75 g (0.12 mol) of sodium iodate was added and the mixture was stirred for about 18 hours at about 60°-65° C. The reaction mixture was filtered through filter paper and then the 1,3-bis(3-aminophenoxy)benzene-p-benzoquinone polymer was precipitated with a about 1:4 mole mixture of methanol and water. The polymer was filtered through filter paper, washed with water and dried in a vacuum desiccator.
