Gustavo Cabrera

Dear Mudassir,

There is a reference of chitosan hydrolysis using potasium peryodate but in spanish. You can download from

file:///C:/Users/Gustavo/Downloads/170-618-1-PB.pdf

It seems that peyodate reaction produce chitosan hydrolysis instead of ring opening like in celullose and other glucan type polymers. This would be do to the amine and acetamide group in chitosan/chitin polymers.

Best regards,

Gustavo
