Sodium saccharin introduction

Saccharin sodium, also known as sodium phthaloyl sulfonimide, was developed in 1879. It is the first synthetic non-nutritive sweetener to be used. It is soluble in water, and its sweetness in dilute solution is 200~500 times that of sucrose. It has a bitter taste when the concentration is high. When heated under acidic conditions, the sweet taste disappears and can form bitter o-sulfamoyl benzoic acid. It is used as a sugar substitute for patients with obesity, hyperlipidemia, diabetes and dental caries because of its low calorie, non absorption, and automatic excretion with urine and urine. In addition, it can also be used as brightening agent, blood circulation measuring agent, penetrant, etc.

Sodium saccharin characteristics and use

In terms of sweetness, the anion decomposed from saccharin sodium has a strong sweet taste, while it has no sweet taste in the molecular state, and it feels bitter. Saccharin sodium has high solubility and solubility, so it has strong sweet taste. After boiling, saccharin sodium will decompose slowly. If it is used with other sweeteners in a proper proportion, it will be closer to the sweet taste of granulated sugar. Saccharin sodium will not cause food dyeing and fermentation.

When its concentration is high, it has a bitter taste. When saccharin sodium is heated under acidic conditions, it will lose its sweetness and form bitter o-sulfamoyl benzoic acid. This substance is colorless and stable in performance. Because its heat is low, it is not easy to be absorbed by the body, but it can be excreted with urine and urine. Therefore, saccharin sodium is used as a substitute for sugar in patients with obesity, hyperlipidemia and other diseases.

Sodium saccharin production

Generally, saccharin sodium is mainly produced by toluene method and phthalic anhydride method. Among them, in the process of producing saccharin sodium by toluene method, o-toluenesulfonamide is generally generated as an intermediate, and the o-toluenesulfonamide will often generate insoluble saccharin after oxidation and acid precipitation. In the actual production process, due to incomplete oxidation, the unreacted o-toluenesulfonamide can not be completely separated, and o-toluenesulfonamide is a carcinogen. In this case, the national industrial policy further limits the development of saccharin sodium industry. For this reason, the state carries out fixed-point production, limited production and limited sales control of saccharin sodium products. For the annual production plan, enterprises need to review and approve, and also have strict management on the use of saccharin sodium products.

Saccharin sodium is still a highly polluting industry. The production of saccharin sodium consumes 14 kinds of chemical raw and auxiliary materials, such as strong acid and strong alkali. Each 1t of saccharin sodium requires 13.2 tons of raw materials and 24 tons of water. The total discharge of its waste is up to 26.2 tons, which usually pollutes the environment. However, in terms of production process, after long-term improvement and continuous improvement, the production process of saccharin sodium has become mature. The domestic production of saccharin sodium from phthalic anhydride has reached the international advanced level in both yield and quality, and has strong competitiveness in the international market.
