Estimation of Parameters of Arrhenius Equation for Ethyl
In this scientific research a Saponification Reaction between Ethyl Acetate and caustic soda is carried out in a Batch Reactor at STP Conditions The aim of this scientific research is to estimate the parameters of Arrhenius equation which are rate constant and activation energy for ethyl acetate saponification
Is saponification reaction of ethyl acetate and sodium hydroxide irreversible?
- Reaction Kinetics: Saponification Reaction of Ethyl Acetate and Sodium Hydroxide is an irreversible 2nd order overall, 1st order with respect to reactants furthermore reaction order decreases and become sequential rather than 2nd order when equimolecular concentrations of both reactants are used7-10.
What chemicals were used in the saponification reaction?
- Chemicals: Analytical reagent (AR) - grade chemicals were utilized to conduct the experiments using PFR and CSTR. Ethyl acetate with 99.5% purity and sodium hydroxide with 98.0- 100% purity were used to carry out the saponification reaction.
What is the alkaline hydrolysis of acetate esters?
- The alkaline hydrolysis of acetate esters, also know as the saponification reaction can be written as: AcO-R + Na+ + OH- ? AcO- + Na+ + R-OH (1) As the reaction proceeds, hydroxide ions are consumed and acetate ions are produced.
What is an example of a reverse saponification reaction?
- is an example of a saponification reaction (the reverse reaction would be esterification). This reaction may be either reversible or irreversible. For the irreversible case, the rate equation for a batch reactor may be written: where k is the rate constant and [A] and [B] are the concentrations of the reactants in the appropriate units.
