High Purity Ethyl Acetate Production with a Batch Reactive Distillation Column using Dynamic Optimization Strategy Abstract—Ethyl acetate with the minimum purity of 85 0 by mole is inevitably needed as an active solvent used in a wide range of applications across many industries

Is industrial manufacture of ethyl ethanoate preferred method of production?

- The gas produced should not be smelled directly instead be wafted to avoid interaction with the respiratory system. Conclusion and evaluations In conclusion, industrial manufacture of ethyl ethanoate is more preferred method of production, as large amount of output of the products is obtained.

What are ethyl ethanoate & ethanol ester?

Esters can be made from carboxylic acids and alcohols. This is discussed in detail on another page; in general terms, the two combine together, losing a molecule of water in the process. Consider a very simple ester such as ethyl ethanoate. The figure below shows its formation from ethanoic acid and ethanol.

What is the maximum purity of ethyl acetate?

It is normally produced by the esterification of ethanol and acetic acid. Due to the equilibrium limitation, it has been reported that the ethyl acetate with the maximum purity of 52.0% can be obtained in a batch reactor. To achieve higher purity, further purification unit is added with the use of some energy.

What does ethylethanoate smell like?

Abundance acid and alcohol bothdissolve and are tucked securely away under the ester layer. Little esters like ethylethanoate smell like ordinary natural solvents (ethyl ethanoate is a common solventin, for example, glues). As the esters get greater, the smells tend towards artificialfruit flavouring - "pear drops", for example.

Vocational Scenario or

Context

You are a lab technician working in the research and development department of a cosmetics company. One of the products made by the company is nail polish remover.

The nail polish remover contains ethyl ethanoate.

You are investigating how to produce and test the purity of ethyl ethanoate so that the company can make it efficiently. You will produce a sample of ethyl ethanoate and test its purity. You will have to compare your laboratory technique with the industrial process used by the cosmetics company to manufacture ethyl ethanoate on a large scale.

Task 1

Prepare a sample of ethyl ethanoate and test its purity, demonstrating skilful application of the techniques you use (ie reflux and distillation using QuickfitTM apparatus, addition of chemicals to purify the ethyl ethanoate and testing its purity by measuring its boiling point and infrared spectrum and comparing with reference information). Write a report detailing your production and testing of ethyl ethanoate in the laboratory. The report must: Explain the scientific principles behind your practical work techniques Give detailed conclusions from your practical work Identify factors that affect the yield and purity of ethyl ethanoate in your laboratory preparation and analyse how significant these factors are Research and describe the industrial manufacture and testing of ethyl ethanoate, including raw materials, equipment and scale of production 2

BTEC Assignment Brief v1.0

BTEC Internal Assessment QDAM January 2015

Compare the laboratory and industrial manufacture

and testing of ethyl ethanoate, explaining principles, similarities and differences in the equipment and techniques used Analyse how relevant the factors you have identified as affecting yield and purity are in the industrial manufacture of ethyl ethanoate

Analyse whether boiling point measurement and

infrared spectroscopy are effective ways to assess purity of a liquid, and draw a conclusion on whether other methods used industrially, such as chromatography, are more reliable.

Checklist of evidence

required A report on the practical work and the detailed conclusions from this, including the analysis of factors affecting yield and purity, and research on industrial manufacture and testing An observation report by the teacher of making and testing the liquid safely.

All information sources should be referenced.

Criteria covered by this task:

Unit/Criteria

reference To achieve the criteria you must show that you are able to: B.D2 Analyse the factors affecting the yield and purity of an organic liquid in the laboratory and their relevance to its industrial manufacture. B.M2 Demonstrate skilful application of techniques in preparing and testing the purity of an organic liquid and draw detailed conclusions. B.M3 Compare the laboratory and industrial manufacture and testing of an organic liquid. B.P3 Prepare and test the purity of an organic liquid and draw conclusions. B.P4 Describe the industrial manufacture and testing of an organic liquid.
