Differentiation Between Keto and Aldehyde Groups

An important issue is the differentiation between aldehyde and keto groups in cellulosic materials. Different approaches are theoretically conceivable a selective derivatization of either aldehyde and keto groups, a mathematical 

Only pulps from cotton linters and rag paper proved to be stable enough to be safely subjected to this method. A combination of the TTC protocol and the CCOA method to obtain pure keto group profiles is given by Nagel et al. [ 177].
