What is the content of ethyl acetate in a banana?
The smell of bananas comes from the ester 3-methylbutyl acetate. Ethyl acetate has a smell similar to that of bananas and is often used in banana fragrances as well as being naturally found in some wines. The ester 3-methylbutyl acetate (isopentyl acetate) is an artificial banana scent/flavor. While we perceive the smell of this compound as the smell of bananas, the chemical is not responsible for the scent/flavor of real bananas. Banana candies (runts for example) use 3-methylbutyl acetate as the artificial flavoring and any true banana lover could tell you that the candies taste different than the fruit.
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.
Can acetone substitute ethyl acetate?
No. In the biochemical World, ketones - of which acetone is just one example, [the -one suffix denotes a specific substance that has a special double bond configuration] - and acids and acetates are not interchangeable.

Is ethyl acetate a good solvent for using TLC plates?
Ethyl acetate is generally a good solvent for TLC. It is more polar than hexanes, but less so than acetone, alcohols, acids, and water. If you are doing a reaction for the first time and have no idea what solvent system to use for TLC, varying ratios of hexanes:ethyl acetate is always a good starting point (try 3:1, 2:1, 1:1, 1:2. 1:3, etc).
Is ethyl acetate bad for your health?
Ethyl acetate is considered safe for most people when used in small amounts, such as in food flavorings or cosmetics. However, inhaling large amounts of ethyl acetate vapor can cause irritation to the eyes, nose, and throat. Prolonged exposure to high levels of ethyl acetate may also affect the nervous system. It is important to use ethyl acetate in a well-ventilated area and follow safety guidelines when handling it.
How is polyvinyl alcohol made?
Polyvinyl alcohol (PVA) is made by the hydrolysis of polyvinyl acetate, which involves breaking down the acetate groups in polyvinyl acetate to form the alcohol groups in PVA. This process typically involves the use of a catalyst and water to facilitate the reaction. The degree of hydrolysis determines the properties of the resulting PVA polymer.

How can you remove water from ethyl acetate by using inorganic salt?
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.

What is hot ice used for?
Instant hot ice is a simple name for the chemical Sodium acetate. It can react with other chemicals to give out a lot of heat in a short time. Its heating property makes it ideal for making heat packs.
What can you use instead of nail polish thinner to thin out nail polish?
Looking at the various material safety data sheets (MSDS) in proprietary nail polish thinner, they all seem to be proprietary formulations with varying amounts of a range of "organic chemical" solvents including: acetone; ethyl acetate; butyl acetate; methyl ethyl ketone; hexane; etc. So the best solvent would be a proprietary nail lacquer thinner. Other options include: solvent acetone; paint thinner; shellite. (I use acetone and it seems to work fine.)
