[Uses]

Sorbitol is a humectant that is a polyol (polyhydric alcohol) produced by hydrogenation of glucose with good solubility in water and poor solubility in oil. It is approximately 60% as sweet as sugar, and has a caloric value of 2.6 kcal/g. It is highly hygroscopic and has a pleasant, sweet taste. It maintains moistness in shredded coconut, pet foods, and candy. In sugarless frozen desserts, it depresses the freezing point, adds solids, and contributes some sweetness. It is used in low-calorie beverages to provide body and taste. It is used in dietary foods such as sugarless candy, chewing gum, and ice cream. It is also used as a crystallization modifier in soft sugar-based confections.

[General Description]

Odorless colorless solid. Sinks and mixes with water.
[Reactivity Profile]

SORBITOL(50-70-4) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

[Product Features]

Sorbitol is a non-volatile polyhydric sugar alcohol. It is chemically stable and not easily to be oxidized by air. It is easily soluble in water, hot ethanol, methanol, isopropanol, butanol alcohol, cyclohexanol, phenol, acetone, acetic acid and dimethyl formamide. It is widely distributed in nature plant fruit. It is not easy to be fermented by various kinds of microorganism and have a excellent heat resistance without decomposing even at high temperature (200 °C). It is initially separated from the mountain strawberry by the Boussingault (French) et al. The pH value of the saturated aqueous solution is 6 to 7. It is isomer of mannitol, Taylor alcohol, and galactose alcohol. It has a refreshing sweet taste with sweetness being 65% of sucrose. It has excellent moisture absorption capability with a low calorific value and has very wide range of effects on the food, cosmetic, pharmaceutical field. When applied in food, it can prevent the food drying, aging, and can extend the shelf life of products as well as effectively prevent the precipitation of sugars and salts contained in the foods and thus maintain the strength balance of sweetness, sour, bitter and enhance food flavor. It can be synthesize from the hydrogenation of glucose under heating and high pressure with the existence of nickel catalyst.
[Uses]

1. Daily chemical industry
Sorbitol can be used as an excipient, moisturizing agents, and antifreeze agents in toothpaste, with the added amount being up to 25 to 30%. This can help maintain the lubrication, color, and good taste for the paste. In cosmetics field, it is used as an anti-drying agent (substitute glycerol) which can enhance the stretch and lubricity of emulsifier, and thus is suitable for long-term storage; Sorbitan esters and sorbitan fatty acid ester as well as its ethylene oxide adducts having a advantage of a small skin irritation which is thus widely used in the cosmetics industry.
2. The food industry
Adding sorbitol into foods can prevent the drying of food and make food stay fresh and soft. Application in bread cake has a significant effect.
The sweetness of sorbitol is lower than that of sucrose, and can’t be exploited by any bacteria. It is an important raw material for production of sugar-free candy and a variety of anti-caries food. Since the metabolism of the product does not cause increase of blood sugar, it can also be applied as a sweetener agent and nutrient agent for the food of patients with diabetes.
Sorbitol does not contain an aldehyde group and is not easily oxidized. It will not have Maillard reaction with amino acids upon heating. It also has certain physiological activity. It can prevent the denaturation of the carotenoids and edible fats and protein; adding this product to the concentrated milk can extend the shelf life; it can also be used to improve the color, flavor and taste of small intestine and has significant stabilizing effect and long-term storage effect on fish pate. Similar effect can also be observed in the jam.
3. the pharmaceutical industry
Sorbitol can be used as raw material in vitamin C; also can be used as feed syrup, injection fluids, and raw material of medicine tablet; as a drug dispersion agent and fillers, cryoprotectants, anti-crystallizing agent, medicine stabilizers, wetting agents, capsules plasticized agents, sweetening agents, and ointment matrix.
4. the chemical industry
Sorbitol abietin is often used as the raw material for common architectural coatings, also used as plasticizers and lubricants for application in polyvinyl chloride resin and other polymers.
It can from complex with iron, copper, and aluminum ion in alkaline solution to be applied to the washing and bleaching in textile industry.
Using sorbitol and propylene oxide as a starting material can produce rigid polyurethane foam as well as have some flame retardant properties.

[Chemical Properties]

It is white and odorless crystalline powder with sweet taste and being hygroscopic. It can be dissolved in water (235g/100g water, 25 °C), glycerin, and propylene glycol; and is slightly soluble in methanol, ethanol, acetic acid, and phenol and acetamide solution but almost insoluble in most other organic solvents.
[Production method]

1. Pour the prepared 53% aqueous solution of glucose into the autoclave, adding the nickel catalyst of 0.1% the weight of glucose; after replacement of the air, add hydrogen at about 3.5MPa, 150 °C, and pH8.2-8.4; control the endpoint with residual sugar content being lower than 0.5%. After precipitation for 5 min, put the resulting solution of sorbitol through ion exchange resin to obtain the refined product. Material fixed consumption amount: hydrochloric acid 19kg/t, caustic 36kg/ t, solid base 6kg/t, aluminum-nickel alloy powder 3kg/t, orally administrated glucose 518kg/t, activated carbon 4kg/t.
2. It is obtained from the hydrogenation of glucose with the nickel catalyst at high temperature and high pressure after which the product is further refined through the ion exchange resin, concentrated,crystallized, and, separated to obtain the final product.
3. Domestic production of sorbitol mostly applied continuously or intermittently hydrogenation of refined glucose obtained from starch saccharification:
C6H12O6 + H2 [Ni] → C6H14O6
Pour the prepared 53% aqueous solution of glucose into the autoclave, adding the nickel catalyst of 0.1% the weight of glucose; after replacement of the air, add hydrogen at about 3.5MPa, 150 °C, and pH8.2-8.4; control the endpoint with residual sugar content being lower than 0.5%. After precipitation for 5 min, put the resulting solution of sorbitol through ion exchange resin to obtain the refined product. The above-mentioned process is simple without the necessity of isolation before obtaining qualified products as well as without "three wastes" pollution. However, for the starch, the yield is only 50%, and thus has a higher cost. Introduction of new technology by direct hydrogenation on starch saccharification liquid can obtain a yield up to 85%.
