Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
In normal-phase TLC, the most common solvent mixtures include ethyl acetate/hexanes (EtOAc/Hex) for less-polar compounds and methanol/dichloromethane (MeOH/DCM) for more polar compounds. [14] Different solvent mixtures and solvent ratios can help give better separation. [15] In reverse-phase TLC, solvent mixtures are typically water with a less ...
After the paint has lost some of the solvent while in storage due to evaporation, paint can become too thick for use, and so paint thinners can be used to dilute or re-dissolve paint to an appropriate consistency. They can also be used as in a paint-brush cleaner to remove or clean items that have become caked in dried-on paint.
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
The solvent also modifies the curing rate and viscosity of the paint in its liquid state. There are two types of paint: solvent-borne and water-borne paints. Solvent-borne paints use organic solvents as the primary vehicle carrying the solid components in a paint formulation, whereas water-borne paints use water as the continuous medium.
Lacquer thinner, also known as cellulose thinner, is usually a mixture of solvents able to dissolve a number of different resins or plastics used in modern lacquer. [ 1 ] Previously, lacquer thinners frequently contained alkyl esters like butyl or amyl acetate , ketones like acetone or methyl ethyl ketone , aromatic hydrocarbons like toluene ...

Ethyl acetate, a nail polish solvent. [1]A solvent (from the Latin solvÅ, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution.A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
