I have isolated salicin from willow bark and my goal is to make acetylsalicylic acid (aspirin). If I have salicylic acid it will be an easy step to make acetylsalicylic acid.I have not found any good methods to form salicin to salicylic acid so far, would be nice to get some help       

Will be thankful if someone solve this headaching problem
