any other things may be present other than what the manufacturer claim). an=
d what is the way to purify glacial acetic acid if at all needed. i am tryi=
ng a reaction which is reported to go almost 85-90% (reaction between phtha=
lic anhydride and diethylene triamine). but i am hardly getting 50-60 % aft=
er repeated experiments. i suspect the solvent.. hence the question. sugges=
tions and other possible reasons for low yield are most welcome.. madhav=
