Stability of cellulose phosphates in alkalic solutions

The stability of cellulose phosphates(III) and cellulose phosphates(V) in suspensions in 2 M potassium hydroxide solutions in the temperature range of 25-80 °C were investigated. The release of phosphorus compounds in eluates was determined by 31 P NMR using methyl phosphonic acid (potassium methyl...

Description
Summary:The stability of cellulose phosphates(III) and cellulose phosphates(V) in suspensions in 2 M potassium hydroxide solutions in the temperature range of 25-80 °C were investigated. The release of phosphorus compounds in eluates was determined by 31 P NMR using methyl phosphonic acid (potassium methyl phosphonate) as internal standard.
