How many moles of acetic anhydride is needed during acetylation of glucose?
How many moles of acetic anhydride is needed during acetylation of glucose?
5 moles
You have seen above in the structure of glucose that there are five hydrogens which are attached to oxygen and they can be replaced by an acetyl group. So there is a need of 5 moles of acetic anhydride needed in acetylation of glucose.
What will be the product of acetylation of glucose?
Acetylation of glucose with acetic anhydride gives glucose pentaacetate which confirms the presence of five-OH groups. Since it exists as a stable compound, five-OH groups should be attached to different carbon atoms.
Why is sodium acetate used in acetylation?
Sodium acetate functions as a buffer of the acetylation reaction mixture and serves as a catalyst. Acetylation under certain conditions can lead to protein denaturation.
When glucose undergoes acetylation with acetic anhydride does it give?
glucose pentaacetate
Glucose reacts with 5 molecules of acetic anhydride to form glucose pentaacetate or penta acetyl glucose.
How many moles of acetic anhydride will be required to form glucose 1 Pentaacetate from I mole glucose?
The above procedure of the art requires at least 5 moles of acetic anhydride to produce 1 mole of glucose penta-acetate and also produces 5 moles of acetic acid by-product.
How many moles are in acetic anhydride?
To calculate the number of moles acetic anhydride from its volume (cell D2) you need its density (1.08g/ml) and its formula mass (102.09g/mol). By typing the following formula in cell C2 you will get the mole of acetic anhydride: =(D2*1.08)/102.06.
What do you mean by acetylation reaction?
Acetylation is a reaction that introduces an acetyl functional group (acetoxy group, CH3CO) into an organic chemical compound—namely the substitution of the acetyl group for a hydrogen atom—while deacetylation is the removal of an acetyl group from an organic chemical compound.
When glucose reacts with bromine water the main product is a acetic acid B saccharic acid C glyceraldehyde D gluconic acid?
When glucose react with Bromine water, then it undergoes oxidation reaction to form Gluconic acid as a product.
What is the role of sodium acetate in imide synthesis?
For instance, in the reaction between aniline hydrochloride and acetic anhydride, sodium acetate is added to the reaction as it helps to release free aniline from its salt form to interact with acetic anhydride to form acetanilide.
Which reagent is used for acetylation?
Silica sulfuric acid as a mild and efficient reagent for the acetylation of alcohols in solution and under solvent-free conditions.
What happens when glucose is treated with sodium acetate and acetic acid?
When glucose reacts with acetic acid it gives Penta acetate. The reaction takes place under the presence of Zinc chloride.
What is meant by acetylation of glucose?
Acetylation of glucose with acetic anhydride gives glucose pentaacetate which confirms the presence of five-OH groups. Since it exists as a stable compound, five-OH groups should be attached to different carbon atoms. CHO CHO O (CHOH), Acetic anhydride, (CH-0-C-CH).
