Why acetylsalicylic acid is not a phenol group?
ASA (acetylsalicylic acid) or Aspirin is synthesised by reacting Salicylic Acid with Acetic Anhydride. During this esterification, the dehydration occurs on the hydroxyl group attached to the benzene ring. As a result, the product no longer possesses the Phenol functional group.
What is the difference between a hydrolysis and neutralization reaction?
Esterification involves the reaction between an alkanol and alkanoic acid while neutralization involves an acid and a base.2. Esterification produces ester and water as product while neutralization produces salt and water only. 3. Esterification is a reversible reaction while neutralization is not.Esterification occurs in the presence of a mineral acid which act as a catalyst and also a as a dehydrating agent while neutralization can occur without been in the presence of a mineral acid.
What is the difference between trans-esterification and esterification processes in methyl esters?
esterification -----> ROH + R'-COOH -------> R'COOR acid with alcohol gives ester transesterification ROH + R'COOR'' -------- > R'COOR change of alkyl group present with R'COO by using a alcohol if you want to http://en.wikipedia.org/wiki/Transesterification Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. H3C-COOH + HO-CH2-CH3 → H3C-COO-CH2-CH3 + H2O Transesterification is the process of exchanging the alkoxy group of an ester compound with another alcohol. These reactions are often catalyzed by the addition of an acid or base.
Could dilute sulfuric acid be used as a catalyst for esterification?
Yes - but it is not very efficient - concentrated is much better. Dont forget that by adding dilute sulfuric acid you are adding water which is produced by the esterification reaction. Although a catalyst does not affect the position of equilibrium, adding a product does (and water is a product) - and so it is not ideal at all as the position of equilibrium is shifted back to starting materials by Le Chetalier's Principle.
What is the product of 1-propanol and acetic acid?
The product of 1-propanol and acetic acid is the compound propyl acetate. This compound is formed through the esterification process, which is a reaction of a carboxylic acid with an alcohol in the presence of a substance like sulfuric acid.
What product has salicylic acid?
You can find Salicylic Acid in a lot of Acne medications.
Why is it necessary to dry your product after esterication?
Water will be the byproduct of esterification and hence the product should be dried (to remove water).
Why is an esterification reaction referred to as an elimination reaction?
Because a water molecule is a product of the reaction
What is another product name for salicylic acid?
salicylic acid is most commonly known as Aspirin (it is the main ingredient in Aspirin)
Can you use a salicylic topical product while taking aspirin?
no

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.
What components in a face cream would prevent pimples?
Most of the time it is salicylic (sp?) acid. Depending on the product.

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)
