Hydrochloric Acid → HCID 18798334, compound

Participants

Reaction Steps

Into 150 ml of 10% NaOH solution made from 1:1 (v:v) mixture of ethanol and water were dissolved 2 g of N,N'-diphenyl-3,6-bis[4-(n-butyloxy)phenyloxy]pyromellitic diimide obtained from above. This solution was refluxed for 72 hr under nitrogen atmosphere and then cooled to ambient temperature. When it was neutralized with 5%, aqueous HCl, white precipitates were formed. These precipitates were filtered, air-dried and recrystallized from 1:1 (v:v) mixture of hexane and ethyl acetate to obtain 3,6-bis[4-(n-butyloxy)phenyloxy]pyromellitic acid.
