Ethyl acetate is commonly abbreviated EtOAc. Formula and structure: The ethyl ethanoate chemical formula is CH 3 COOCH 2 CH 3 and its condensed formula is C 4 H 8 O 2. These schemes are accessible even at relatively low centrifugation speed for molecules that float and sediment with apparent molar masses several hundred times larger than the molecular mass. Ethyl acetate, also known as ethyl ethanoate, is an important chemical compound very used as solvent in many chemical reactions. These findings open new possibilities of centrifugal separation, even if control is delicate during temperature cycles. Nevertheless, they are usable when accompanied by temperature cycles.
The concentration gradients are small except near the critical point, as expected for small molecules.
The experimental equilibrium composition profiles behave qualitatively as expected and can be predicted using a phenomenological theory of mixing. The molecular weight of ETHYL ACETATE is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be: 88. While you may not have heard of ethyl acetate, you’re likely familiar with some of the products it’s used in: Nail polish remover. This chemical is used commonly due to its low cost and agreeable aroma.

The expected composition profiles of samples after centrifugation can be represented by bent lines in a ternary phase diagram when gravitational energy is added to the free energy of mixing. The ETHYL ACETATE molecule consists of 8 Hydrogen atom (s), 4 Carbon atom (s) and 2 Oxygen atom (s) - a total of 14 atom (s). Ethyl acetate is manufactured on a large scale, as over 1 million tons are produced annually in the world. We show that two different types of phase separation can be induced upon centrifugation in this ternary system using ethanol as a co-solvent of water and ethyl acetate (EA): centrifuge-induced criticality and centrifuge-induced emulsification.
Water-ethyl acetate-ethanol is widely used as “green” extractant system.
