Molecular formula : C12H22O11
MW : No. 57-1 342.30
CAS-50-1
nature : colorless single-crystal wedge ramp, a white crystalline or granular powder. The relative density of 1.587 (25 / 4 ° C). The 160-186 ° C decomposition. Water-soluble, 1g of the materials can be dissolved in 0.5 ml of water, 170ml of ethanol, about 100 ml of methanol. Stability in the air.
Preparation : from the large number of sugar cane and sugar beet and sugar cane sucrose content of about 15-20%, 10-17% with beet. Various other fruits, seeds, leaves, flowers, roots have different content. Sugarcane Act to extract fluid or slices of beet juice made of water with lime clarify the law or a combination of sulfiting bun filling, juice to remove impurities, vacuum filter will steamed concentrated filtrate, recrystallization derived from raw sugar, then bleaching, recrystallization derived refined sugar.
purposes : Sucrose is the most common of food and sugar, the system is also used citric acid, caramel, sugar, transparent soap. Sucrose in high concentration can inhibit bacterial growth, medically for preservatives, antioxidant pills such as excipient. 1980 World raw sugar output of 87.1 million t, of which 52 million t sugar, beet sugar t 35 million. From sugar cane and beet sugar by natural conditions, the slow development of the restrictions, the world aglycaemia than more serious. In addition, various special needs, and promoting a new drought sweetener research and development, have now identified a number of natural and synthetic materials sweet sweet material. Sucrose reagents for 1-naphthol determination, but also for calcium, and magnesium from the preparation of biological medium.
