Product Name:Sucrose
CAS Number:57-50-1
Molecular formula:C12H22O11
Molecular Weight:342.3

Sucrose is obtained from the sugar cane plant, which contains 15–20% sucrose, and sugar beet, which contains 10–17% sucrose. Juice from these sources is heated to coagulate water-soluble proteins, which are removed by skimming. The resultant solution is then decolorized with an ion-exchange resin or charcoal and concentrated. Upon cooling, sucrose crystallizes out. The remaining solution is concentrated again and yields more sucrose, brown sugar, and molasses.

Methods

The initial reaction solution, containing 0.1746 g cellobiose, 87.3 mg catalyst, and 25 mL of deionized water, was sealed and heated and kept at the desired temperature. Before sealing, N₂ gas was passed into the solution for 30 min. The magnetic catalyst was recovered by magnetic separation, washed, and vacuum dried. Concentrations of cellobiose, glucose, fructose, and other products in the reaction solution were determined quantitatively by HPLC with an external standard method by comparing to a standard sample. The pH was adjusted with H₂SO₄ or NaOH. On a carbon basis, the conversion of cellobiose X was calculated as X = (C₀ - C_t)/C₀. The yield of the monosaccharide Y₁ was calculated as Y₁ = C₁_t/2C₀. The yield of sucrose Y₂ was calculated as Y₂ = C₂_t/C₀. The selectivity of glucose S was calculated as S = Y₁/X, where C₀, C_t are the concentrations of cellobiose at reaction times t = 0 and t, respectively, and C₁_t, C₂_t are the concentrations of the monosaccharide and sucrose at time t, respectively.
