Versuchsvorschrift

Into a reaction vessel equipped with a condenser, light nitrogen purge and magnetic stirrer, 10 g (0.022 mol) of tetraphenylphthalic anhydride and 3.35 g (0.022 mol) of 3,4 diaminobenzoic acid are added, along with 100 ml of acetic acid. The gray colored reaction mixture is heated to reflux temperature. After several hours the reaction begins to take-on a dark yellow color. The reaction mixture is then left for a further 72 hours at slightly below reflux temperature (105° C.).
