Description

Organic compound, adduct of glucose an sodium chloride. From water solutions crystallizes as monohydrate.

Reaction between glucose and sodium chloride

Chemical equation:

2C6H12O6 + NaCl = 2C6H12O6 · NaCl


For preparation of 100.00g of glucose and sodium chloride adduct monohydrate а 82.49g of glucose and 13.38g of sodium chloride is required.

Dissolve compounds in hot water apart and then mix solutions into one container with intense stirring. Cooling or evaporation of a solution will cause double salt crystallyzation.

Notes

Due to high solubility and high solution viscosity, each particle of dust makes a crystallization center, forming a large number of small crystals. To get large monocrystals, it is recommended to cover a container with the solution with cardboard or parer, with small hole in it to ensure slow water evaporation.
Fast growth produces crystals with shape of elongated bipyramid. Slow growth produces crystals with shape of rhomrohedron and beveled prisms.

Keep in its original form or under several layers of varnish at average humidity and room temperature. Do not keep crystals near heaters.
