Alias name: D(-)sorbitol, nerolidol, sorbicolan, diakarmon.
English name: sorbitol D-g1ucitol, diakarmon, nivitin.
Molecular formula: C 6 H 14 O 6 . Molecular weight: 182.17.
Crystal product is a white crystal powder, odorless, with cool sweet taste. Its sugariness is half of that of sucrose, with slight hygroscopicity. It can be easily soluble in water and ethanol. 5.48% sorbitol water solution is an isotonic solution. Melting point is varied in the range of 97-102 based on different crystallization conditions, relative density 1.489, refractive index 1.3477 (10% water solution), soluble in water (235g/100g water, 25), glycerine and propylene glycol, slightly dissolved in methanol, ethanol, acetic acid, phenol and acetamide solutions. It is hardly dissolved in most other organic solvents, with a caloric powder equal to that of sucrose. Sorbicolan solution is clear colorless syrup, with sweet taste, neutral in litmus solution, and it can be mixed with water, glycerine and propylene glycol. CAS number: 50-70-4.
Sugariness of sorbitol is lower than that of sucrose, and it can not be utilized by some bacteria. It can be used extensively in food industry, leather, cosmetics, paper, textile, plastic, toothpaste and rubber industries. It also can prepare alkyd resin as plasticizer and antifreezer. In production of toothpaste, tobacco, tanning and ink, sorbitol can be used to replace glycerine as the moisture controlling reagent. It can also be used as the material of emulsifier, thickening agent, dispersing agent and rust inhibitor in resin and dynamite preparations.
