In synthesis of p-toludine there is possibility of formation of O-toludine which is consider as a impurity.
in the synthesis of p-toluidine- what impurities likely to be present?
What is the maximum number of grams of N-acetyl-p-toluidine can be prepared from 70. milliliters of 0.167 M p-toluidine hydrochloride and an excess of acetic anhydride in an acetate buffer? (use N-acetyl-p-toluidine = 149.19 g/mol)
What is the maximum number of grams of N-acetyl-p-toluidine can be prepared from 70. milliliters of 0.167 M p-toluidine hydrochloride and an excess of acetic anhydride in an acetate buffer? Enter only the number with two significant figures.
