Pharmatose 150M - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Overview | sucrose, the main component of sugar, it is formed by condensation and dehydration of a hemiacetal hydroxyl group of one molecule of glucose and a hemiacetal hydroxyl group of one molecule of fructose. Its content in sugar cane, sugar beet and maple juice is particularly rich. Sucrose has a sweet taste and is an important food and sweet flavoring. |
| preparation method | the raw materials of sucrose are mainly sugar cane (sugar cane spp.) and sugar beet (Beta vulgaris). The sugar cane or sugar beet is crushed with a machine, the sugar juice is collected, filtered and treated with lime to remove impurities, and then bleached with sulfur dioxide; The treated sugar juice is boiled and the impurities in the bottom are removed, the foam floating onto the surface was scraped off and then quenched until the syrup crystallized into sucrose. |
| purpose | used as analytical reagent, chromatographic analysis reagent, also used in the preparation of biological media isolation of nitrilactose in GLC properties: a disaccharide isolated from mammalian milk. Milk containing about 4%-5%, human milk containing about 6.7%. Equal molecules of D-glucose and D-galactose are obtained by acidic hydrolysis. It is a reducing sugar, which can reduce the Ferrin solution. Α-lactose is obtained by crystallization in aqueous solution at normal temperature, and β-lactose is obtained by crystallization above 93 ℃. Alpha-lactose is the common form of lactose. There is a weak sweet taste, usually with a molecule of crystal water. Monoclinic crystal. Loss of crystal water at 120 ℃, rapid heating, the aqueous solution of change rotation phenomenon,[a]20D-92.6 ° → +83.5 °(10 min) → +69 °(50 min) +52.3 °(22 hours). Beta-lactose is slightly softer than alpha-lactose. White crystals. Melting point 252 °c. The aqueous solution also has the phenomenon of change rotation. [Α] 25D +34 °(3 min) → +39 °(6 min) → +46 °(1 hr) → 52.3 °(22 hr). After absorbing water at room temperature, β-lactose can be converted into α-lactose, which is changed into β-lactose when heated to above 93 °c. Xylenes and xylene isomers are components of the liquid-solid phase. chromatographic adsorbent. Bacterial culture medium. |
