Sodium Hydroxide → Muconic Acid

Participants

Reaction Steps

23.5 Grams (0.1 mole) of β, β'-dimethoxy-adipic acid-dimethylester were boiled under reflux with a solution of 32 g of NaOH in 50 ml of water for 8 hours, were cooled, suction-filtered, dissolved in water, were precipitated with concentrated hydrochloric acid at a pH value of 1, were washed with water until neutral and dried. 12.2 Grams (86 % of the theoretical yield) of trans, trans-muconic acid were obtained which had a melting point of from 298° to 300° C.
