Chemical features:
sorbitol and mannitol, Taylor, galacitiol alcohol for oil, chemical stability, sorbitol by air oxidation, and alkali doesn't work, By all kinds of microorganism fermentation, Heat-resisting performance is good, Under the high temperature (200 ° c) and do not break down,Sorbitol as six yuan alcohol, under high temperature conditions can generate generating sorbitol anhydride, dehydration, Under high temperature conditions can radiochemical, carbon chain rupture and glycol and glycol butyl alcohol; four, In the presence of catalyst with organic acid ester of esterification, condensation with aldehyde.
Application:
Sorbitol is widely applied to foodstuff industry. It can be used as raw material of synthetic vitamin C in medicine. And used as plasticizer of resin, surfactant, substitute of glycerin in producing toothpaste and tobacco for moisture control agent, as ethylene glycol and glycerin antifreeze mixed agent, and as sugared substitute materials.
It should be stored in a cool, shaded, dry environment, away from sunlight. Do not store it together with poisonous or harmful goods in order to avoid pollution. For better results, especially for longer periods.
