What is the mechanism of the salicylic acid and acetic anhydride reaction?
The reaction between salicylic acid and acetic anhydride involves the substitution of a hydroxyl group in salicylic acid with an acetyl group from acetic anhydride. This reaction is catalyzed by an acid, typically sulfuric acid, and results in the formation of aspirin and acetic acid as byproducts.
What is the chemical reaction between acetic anhydride and salicylic acid?
The chemical reaction between acetic anhydride and salicylic acid is called esterification. This reaction forms acetylsalicylic acid, which is commonly known as aspirin.
What is the balance chemical equation of acetic anhydride?
The balanced chemical equation for the reaction involving acetic anhydride (C4H6O3) is: 2C4H6O3 → 4CH3COOH + (CH3CO)2O
What is the balanced equation for the reaction of salicyclic acid and sodium hydroxide?
The balanced equation for the reaction between salicylic acid and sodium hydroxide is: C7H6O3 + NaOH → C7H5NaO3 + H2O
Is the reaction between salicylic acid and acetic anhydride exothermic?
A reaction between an alcohol and an anhydrid is usually exothermic, so I would say it is.

What percent salicylic acid in aspirin?
37.16% is the expected yield in the reaction of salicylic acid and acetic anhydride used to form aspirin.
How do you know which OH group on salicylic acid reacts to form aspirin?
Aspirin is formed in a reaction between salicylic acid and acetic anhydride. In this reaction it is the phenolic alcohol group that reacts to form the aspirin.
What is the equation for the reaction of salicylic acid with Acetyl chloride and pyridine?
The reaction of salicylic acid with acetyl chloride and pyridine results in the formation of acetylsalicylic acid (aspirin). The general equation for this reaction is: salicylic acid + acetyl chloride → acetylsalicylic acid + hydrogen chloride
What chemicals are needed to produce aspirin?
The ingredients needed to produce aspirin are salicylic acid and acetic anhydride. Acetic acid is also produced as a byproduct during the chemical reaction.
Aspirin is made by the reaction of salicylic acid with acetic an hydride what is the theoretical yield of aspirin if 85.0 grams of salicylic acid is treated with excess acetic an hydride?
Since salicylic acid is being reacted with excess acetic anhydride, salicylic acid is the limiting reactant of the reaction. The balanced equation of the reaction of salicylic acid and acetic anhydride indicates that their is a 1:1:1:1 ratio between every reactant and product. Based on this, it can be concluded that the moles of salicylic acid, if reacted entirely, will yield an equivalent amount of moles of aspirin. To find the theoretical yield, you must know the molecular weight of aspirin and salicylic acid. First, the amount of moles of salicylic acid must be calculated by dividing the gram amount of salicylic acid, which is 85 grams, and dividing it by its molecular weight, which is 138.12 grams per mole.85.0/138.12= 0.615 moles of salicylic acidThis is the mole amount of salicylic acid as well as the theoretical mole amount of aspirin. To convert the mole amount of aspirin into grams, this figure be multiplied by the molecular weight of aspirin, which is 180.15980.615 x 180.1598 = 111 grams of aspirin (when rounded to 3 significant figures)
What is mechanism reaction between salicylicacid and acetic anhydride?
acetic an hydride formula is (CH3CO)2O in salicylic acid for benzene ring OH and COOH are present ortho to each other. When we terate the acetic an hydride with salicylic acid, Hydrogen as a positive charge from slicylic acid (from OH not from COOH) and CH3COO as a negetive chare will replaces and finally acetyl salicylicylic acid will form,it is also called as ASpirin.acetic acid is also forms
