D-Gluconolactone or Gluconolactone or Glucono delta-lactone SDS of Manufacturers
CAS Number 90-80-2 D-Gluconolactone or Gluconolactone or Glucono delta-lactone, EINECS: 202-016-5, Molecular Weight: 178.14, Chemical Formula: C6H10O6
Gluconolactone USP Grade Specifications
C6H10O6 -- 78.14
D-Gluconic acid -lactone.
Glucono delta-lactone CAS 90-80-2
Gluconolactone contains not less than 99.0 percent and not more than 101.0 percent of C6H10O6.
Identification: Dissolve about 0.5 g in 5 mL of warm water in a test tube. Add 1 mL of freshly distilled phenylhydrazine, and heat on a steam bath for 30 minutes. Cool the solution, induce crystallization by scratching the inner surface of the test tube with a glass rod, and collect the crystals of the phenylhydrazide of gluconic acid. Dissolve the crystals in 10 mL of hot water to which a small amount of activated charcoal has been added, filter, recrystallize, wash the crystals with 2 mL of cold water, and dry the crystals at 105 for 1 hour: the crystals so obtained melt between 195C and 200C.
Lead: ---: the limit is 0.001%.
Heavy metals: ---: the limit is 0.002%.
Reducing substances: Transfer 10.0 g to a 400-mL beaker, add 40 mL of water, and swirl to dissolve. Add 2 drops of PhPh, and neutralize with sodium hydroxide solution (1 in 2). Dilute with water to about 50 mL, and add 50 mL of alkaline cupric tartrate. Heat so that the solution begins to boil in 4 minutes, and allow boiling to continue for 120 seconds. Pass the suspension through a medium-porosity filtering crucible, and wash the filter with three 5-mL portions of water. Place the crucible in an upright position in the original beaker, add 5 mL of water and 3 mL of nitric acid to the crucible, mix with a glass rod to ensure complete solution of the cuprous oxide, and wash the solution from the crucible into a beaker with the aid of 5 mL of water. Add bromine, usually 5 to 10 mL, until the solution becomes yellow in color, and dilute with water to about 75 mL. Add a few glass beads, boil until the bromine has been driven off, and cool. Slowly add ammonium hydroxide until a deep blue color appears, then adjust with glacial acetic acid to a pH of 4, and add water to make about 100 mL. Add 4 g of potassium iodide, and titrate with 0.1 N sodium thiosulfate, adding starch just before the endpoint is reached: not more than 16.1 mL of 0.1 N sodium thiosulfate is consumed.
