    Is this in a lecture course or a lab course? In real organic chemistry (lab), forming the product is often only a small part of the work involved. In many cases, it will take more effort to isolate the product than to perform the reaction.

    it is in lab exercise. we reacted Acetic Anhydride and Salicylic Acid by placing the substance in a flask and it was heated. then it was crystallized to obtain ASA and further subjected to filtration. there's this question that ask the reactions that takes place during the experiment and we have to provide the step by step chem. equation for each. and we are ask to have like around 5-7 steps..
    and i just have lone step for the whole thing..

    It's acid catalyzed. Use that in the first step. Do you think it reacts with the phenol or the anhydride in the first step? How?

    Hi I read somewhere that the Acid you refer too can be extracted by "Distilling Powdered Coal ie Coal Dust" Potassium Cyanide can be made in a similar fashion so I have read, Im afraid thats all I can tell you, hope it is of some use to you.
