The eluent used was ethyl acetate containing 05 - Course Hero

This eluent was used because ethyl acetate is a semi-polar solvent and acetic acid is a polar solvent. This type of polarity is needed in order for the TLC plate to efficiently develop. The plate itself is polar because of the silica therefore, this makes it difficult for any polar compound to separate do to their attrition to the silica.

Ethyl acetate - Wikipedia

Ethyl acetate is used primarily as a solvent and diluent, being favored because of its low cost, low toxicity, and agreeable odor. [5] For example, it is commonly used to clean circuit boards and in some nail varnish removers ( acetone is also used). Coffee beans and tea leaves are decaffeinated with this solvent. [10]

Ethyl Acetate - an overview ScienceDirect Topics

Ethyl acetate is an important organic compound with the formula CH3 COOCH 2 CH 3, which has a special sweet smell. As a chemical reagent, ethyl acetate is always used in glues, decontaminants, and oil removers. In addition, for the low cost, low toxicity, and agreeable odor, ethyl acetate is mainly used as a solvent or diluent.

What are TLC plates made of? Hasorno

Why is ethyl acetate a good solvent for TLC? Ethyl acetate is a polar solvent, but it is often used in TLC. TLC''s stationary phase is usually silica gel, which is polar. I thought the whole point of TLC is to separate the polar compounds (travels less, low Rf) and nonpolar compounds (travels farther, high Rf).

What is the use of ethyl acetate in extractions? - Quora

Why is ethyl acetate highly used as a solvent to run TLC? In TLC the component of the mixture is separated. This is achieved by using a stationary phase (normally silica) and a mobile phase. The mobile phase (Solvent) rises through the column by capillary. When it rises (Elutes) it carries the sample also. Here polarity plays an important role.

Ethyl Acetate - Structure, Formula, Properties, Production and …

Ethyl acetate is synthesized on a large scale because it is widely used as a solvent for many compounds. In industries, it is synthesized by the Fischer esterifiion reaction. In this reaction, ethanol and acetic acid are used as reactants. The reaction takes place at room temperature which gives 65% yield. The reaction is given below –
