General description
Sodium carbonate decahydrate is a hydrated form of Na2CO3. IR spectral investigations suggest its spectra is similar to the heptahydrate form. It undergoes thermal dehydration to monohydrate form in a batch, fluidized bed reactor.
Application
Sodium carbonate decahydrate may be used to investigate the hydrolysis of poly(β-cyclodextrin-co-citric acid) (CDP, water-insoluble polymer). Polymeric hydrolysates were investigated by HPLC.
