Investigation of the chemical structure of saccharates and calcium sucrocarbonates

, : Investigation of the chemical structure of saccharates and calcium sucrocarbonates. Gazeta Cukrownicza 100(12): 221-226

The nature of saccharates was studied using 13C-NMR. Solutions containing sucrose (0.585 M) and lime (0.679 M) reacted to form a complex comprising sucrose, Ca2+ and OH-. NMR measurements indicated that the OH-group attached at position C-4' on the fructofuranose ring was involved. Probably a hydroxyl ion is hydrogen-bonded to the H-atom while the O-atom (via a free electron pair) coordinates with Ca2+; the existence of sucrose anions is unnecessary in this theory.

As carbonatation proceeded the viscosity increased proportio...
