说明

一般說明

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.

應用

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.
