Sodium saccharine factory
Sodium saccharine factory
Sodium saccharin, also known as saccharin, is known as sodium sodium phthalates. White prismatic crystallization. Molecular weight 205.17. Melting point 226 to 231 degrees C. Odorless or slightly aromatic, the taste is extremely sweet with bitter, slowly weathering in the air, losing about half of the crystalline water and turning it into a white powder. The sweet taste of the dilute solution is about 300 to 500 times that of sugar, and the sweetness threshold is about 0.00048%. Soluble in water and slightly soluble in ethanol. Its thermal stability in the aqueous solution is better than saccharin, and there is no change in heating 2h at 100 degrees C. The aqueous solution is placed for a long time and the sweetness decreases slowly. Mainly used as a sweetener. In the human body does not break down, with urine discharge, no nutritional value. Produced from phthalates or toluene as raw materials.
Chemical properties
Colorless to white oblique crystalline plate crystallization or white crystalline weathering powder. No odor or slight odor. Very sweet, even in 10000 times the water solution is still very strong sweet, sweet threshold of about 0.00048%. The sweetness in the dilute solution is about 500 times that of sucrose. When the concentration is sweet, thick (greater than 0.026%) has a bitter taste, so the concentration when used alone should be less than 0.02%. Heating under acidic conditions, the sweetness disappears. And can form bitter neighbor amino sulfonamide benzoic acid. Soluble in water (1g/1.5m1) and slightly soluble in ethanol (1g/50m1).
