Reducing agents glucose

Copperil) oxide, CujO, occurs naturally as the red cuprite. It is obtained as an orange-yellow precipitate by the reduction of a copper(II) salt in alkaline solution by a mild reducing agent, for example glucose, hydroxylamine or sodium sulphite ... 

Traditionally, these dyes are appHed from a dyebath containing sodium sulfide. However, development in dyeing techniques and manufacture has led to the use of sodium sulfhydrate, sodium polysulfide, sodium dithionite, thiourea dioxide, and glucose as reducing agents. In the reduced state, the dyes have affinity for cellulose (qv) and are subsequendy exhausted on the substrate with common salt or sodium sulfate and fixed by oxidation. 

A dichromate or chromate solution is reduced under pressure to produce a hydrous oxide, which is filtered, washed, and calcined at 1000°C. The calcined oxide is washed to remove sodium chromate, dried, and ground. Sulfur, glucose, sulfite, and reducing gases may be used as reducing agent, and temperatures may reach 210°C and pressures 4—5 MPa (600—700 psi). 

Azoxy compounds can be obtained from nitro compounds with certain reducing agents, notably sodium arsenite, sodium ethoxide, NaTeH, NaBH4—PhTeTePh, and glucose. The most probable mechanism with most reagents is that one molecule of nitro compound is reduced to a nitroso compound and another to a hydroxylamine 119-42), and these combine (12-51). The combination step is rapid compared to the reduction process. Nitroso compounds can be reduced to azoxy compounds with triethyl phosphite or triphenylphosphine or with an alkaline aqueous solution of an alcohol. ... 

Silver nitrate complexed with ethylenediamine and glucose and other reducing agents have been used to grow silver films by SILAR. After annealing at 300 °C the films showed cubic structure and the I-V curves exhibited linear behavior, whereas the as-grown films showed nonlinear behavior.125... 

Glucose is also used as the reducing agent in the preparation of organic compounds. Wood sugars have reducing properties that are equivalent to those of products for like purposes from any source. 

Reduction of copper(II) hydroxide, Cu(OH)2 with sulfur dioxide, glucose, or another reducing agent. 

No 2 solns in amts sufficient to fill half of a test tube and fill the remaining half with an equal volume of glycerin. Stopper the tube so that no air remains under stoppei and let it stand for 12 hrs. A reddish ppt indicates the presence of reducing agents which will interfere in testing for glucose or sugar, unless the ppt is removed by filtration... 

A particularly interesting and general reducing system for the preparation of azoxy compounds uses a strongly alkaline glucose solution as a reducing agent.
