Sucrose crystalline adducts

Complex-formation between salts and carbohydrates is not a new subject. Crystalline adducts of sugars with inoiganic salts have been studied since 1825, when an adduct of D-glucose with sodium chloride was first described, mainly for the purpose of isolating and purifying sucrose and D-glucose. These studies were not particularly rewarding in a paper on the adduct of sucrose with sodium chloride, presented to The Chemical Society in 1871,... 

In the crystalline state, however, there being no, or only a few, solvent molecules present, hydroxyl groups of any carbohydrate may coordinate to any cation. Crystalline adducts of sucrose with numerous salts, in stoichiometric proportions, are known and yet, in aqueous solution, there is no detectable complex-formation between sucrose and any cation. In this chapter, these cryst ne adducts will not be regarded as complexes and will not be treated, except where their structure throws light on the nature of complexes formed in solution. 

This resulted in a crystalline adduct containing sucrose benzoate and two moles of carbon tetrachloride. All previous and subsequent reports of sucrose octabenzoate describe only an amorphous product. This Ness-Fletcher adduct returned to the amorphous state after removal of the carbon tetrachloride under vacuum. This amorphous state is a second important characteristic of sucrose benzoate.
