Depending on the Quantity of ethyl acetate, use a DESSICATOR.
In the bottom of the dessicator place a crucible of phosphorus pentoxide put in the perforated separating try. In another crucible put in the 'wet' ethyl acetate', on top of the separating try.
Using silicon grease, grease the edges of the dessicator bowl and the dessictor lid. Place the lid on the bowl so that it snugly fits. The dessicotor lid should have an evacuation value, to which attached a gas tight, but flexible hose, and the other end to the evacuation pump.
Turmn the pump on and leave for say 24 hours. , until the phosphorus pentoxide goes black. This should dry out the ethyl acetate, suitabloe for IR or nmr analysis.
Another way, is to put the sample in a 'Muffle Furnace' at about 95 oC. However, this might thermally decompose the ethyl acetate.
NB To dispose of the phosphorus pentoxide safely, slowly place spatula amounts in flowing cold water.
NNB Whilst phosphorus pentoxide is NOT a salt, it will absorb water.
A salt to try is anhydrous calcium chloride.
You can remove water from ethyl acetate by adding anhydrous inorganic salt, such as magnesium sulfate (MgSO4), which will absorb the water. After adding the salt, the mixture needs to be stirred and then filtered to separate the dry ethyl acetate from the solid salt and water.

How do you separate mixture of methanol and ethyl acetate?
You can separate a mixture of methanol and ethyl acetate by using fractional distillation. Since they have different boiling points (methanol: 64.7°C, ethyl acetate: 77.1°C), you can heat the mixture to a temperature between the two boiling points to selectively vaporize and collect each component.
Why it is more useful to make ethyl acetate with acetic acid and alcohol rather than using other compounds like ketene alcohol or acetamide alcohol?
The reaction between acetic acid and alcohol to produce ethyl acetate is a simple and cost-effective process. These starting materials are readily available and less hazardous compared to using ketene or acetamide, which are more complex and toxic. Additionally, the acyl substitution reaction between acetic acid and alcohol is more selective and yields higher purity of ethyl acetate.
What are the chemical tests to distinguish between ethyl ethanoate and butanoic acid?
One way to distinguish between ethyl ethanoate (ethyl acetate) and butanoic acid is by using litmus paper. Ethyl ethanoate is neutral, so it will not affect the color of the litmus paper. Butanoic acid is acidic and will turn blue litmus paper red. Another test is to conduct a smell test - ethyl ethanoate has a fruity smell, while butanoic acid has a strong, rancid smell.

What would the result be if while carrying out TLC chromatography you used a solvent of 200 is to 1 ethyl acetate and aqueous ammonia instead of 200 is to 1 ethyl acetate and acetic acid?
Using ammonia instead of acetic acid as the aqueous component in the solvent mixture for TLC could result in different selectivity and polarity interactions between the stationary and mobile phases. The choice of ammonia may affect the separation efficiency and resolution, leading to different migration distances and spots on the TLC plate compared to using acetic acid. It is important to consider how the change in solvent composition may impact the separation of the compounds being analyzed.
How do you remove moisture from ethyl acetate?
You can remove moisture from ethyl acetate by using drying agents such as anhydrous magnesium sulfate or molecular sieves. Simply add the drying agent to the ethyl acetate, stir or shake the mixture, and then filter the solution to remove the drying agent. This process will help remove any remaining moisture present in the ethyl acetate.

How do you break down caffeine?
There are many different methods to remove the caffine. one way is below, it is a long process and not easy. It would be much easier to just buy decaf at your local market.In the direct method the coffee beans are first steamed for 30 minutes and then repeatedly rinsed with either methylene chloride or ethyl acetate for about 10 hours. The solvent is then drained away and the beans steamed for an additional 10 hours to remove any residual solvent. Sometimes coffees decaffeinated using ethyl acetate are referred to as naturally processed because ethyl acetate can be derived from various fruits or vegetables. However for the purpose of decaffeination it is not generally possible to create such a large quantity of ethyl acetate, thus the chemical is synthetically derived.WOW Gouch53 you are a brainiact i didn't even know you could.-Lovestinks10

How do you make a 3M HCl solution in Ethyl acetate?
To make ethyl acetate, react ethanol with ethanoic acid in the presence of concentrated sulphuric acid. Another method is by preparing industrially using the Tishchenko reaction by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst.
How does twinings decaffeinate their tea?
Twinings decaffeinates their tea using a process called the ethyl acetate method. In this method, the tea leaves are steamed to open their pores, then rinsed with ethyl acetate to remove caffeine. Ethyl acetate is a solvent that selectively binds to caffeine molecules, leaving the other compounds in the tea intact. The tea leaves are then dried to remove any remaining solvent, resulting in decaffeinated tea.

Is ethyl acetate a good solvent for using TLC plates?
Yes, ethyl acetate is a common solvent used in thin-layer chromatography (TLC) due to its moderate polarity and volatility. It is particularly useful for separating organic compounds that are not very polar. However, the choice of solvent also depends on the specific compounds being analyzed on the TLC plates.
What is the Rf value of salicylamide?
It will depend on the solvent system you are using.
What is the RF value for paracetamol?
That depends on many factors including the elution solvent used, the type of TLC plate used, etc.. When using .5% of acetic acid in ethyl acetate as your elution solvent and on a plastic backed plate, the Rf-value should be around 79.82%
