Which catalyst is used in any esterification?
An acid catalyst is used can be in many forms such as sulfuric acid or ion-exchange resin.
Which catalyst is used in esterification of glycerol and butyric acid?
for glyceriol it is HNO3
Is sulphuric acid a positive catalyst?
Yes, it sometimes can catalyze esterification and nitration reactions
What type of alcohols is fischer esterification limited to?
Primary and secondary alcohols are commonly used in the process and work efficiently with an acid catalyst but tertiary alcohols can also be used in some cases under the right conditions. One the reasons that it is more difficult to use tertiary alcohols is because of the steric hinderance which exists in the molecule so there is too much molecular interaction for a stable compound to form.
How you can synthesise procaine?
Try an acid catalyzed esterification of p-aminobenzoic acid with 2-diethylamino-ethanol. Use ~3.5 equivalents of sulfuric acid as the acid catalyst (note 2 of these will be used up to protonate nitrogens while the esterification takes place). reflux for ~2 hours, quench with sodium carbonate to mop up the acid afterwards, then recrystallize from a suitable solvent (maybe ethanol/water mix).Note the above is just a guess and may need further refinement.

Why Sulfuric acid added to the esterification reaction?
works as a catalyst to speed up reaction

Yes, it sometimes can catalyze esterification and nitration reactions
Which catalyst is used in esterification of glycerol with acetic acid?
Usually, the catalysts used for the acetylation (esterification with acetic acid) of glycerol are transition metallic oxides.For instance - ZrO2, WO3, TiO2, MoO3 and others.
What is the equation of the formation of 1-Pentyl Acetate?
If formed by esterification from pentanol and acetic acid it would be C5H11OH + CH3COOH (plus acid catalyst)------> C5H11OOCCH3 + H2O
What is the role of the mineral acids in the esterification process?
esterification is between an organic carboxylic acid and alcohol but sulphuric acid is required in mechanism which converts the carboxylic acid molecule into a carbonium ion which reacts with alcohol and forms an ester.
What is the process of making aspirin?
Aspirin is made when salicylic acid and acetic anhydride is reacted in the presence of an acid catalyst such as H2SO4. Acetylsalicylic acid (aspirin) and acetic acid is formed. The reaction is an esterification reaction.
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.
Meaning of esterification?
esterification is the formation of esters between the reaction of alkanol and alkanoic acid
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.

Primary and secondary alcohols are commonly used in the process and work efficiently with an acid catalyst but tertiary alcohols can also be used in some cases under the right conditions. One the reasons that it is more difficult to use tertiary alcohols is because of the steric hinderance which exists in the molecule so there is too much molecular interaction for a stable compound to form.
