Organic Chemistry - Lab Report ExampleThe root of obscures from these infixed products is an example of solid/ smooth-spoken blood-the solid being the natural product and the politic being the resolvent into which the compounds are extracted. In research, a Soxhlet extractor is often used for solid/liquid extraction.Although solid/liquid extraction is the most commonalty technique for brewing beverages and isolating compounds from natural products, liquid/liquid extraction is a very common method used in the organic laboratory, specifically when isolating reply products. Reactions are typically homogeneous liquid mixtures and can therefore be extracted with either an organic or aqueous solvent. Organic reactions often yield a number of by products- whatsoever inorganic and some organic. Also, because some organic reactions do not go to 100% completion, a small amount of starting stuff and nonsense is present at the end of the reaction. When a reaction is complete, it is nec essary to do a workup, that is, separate and ameliorate the desired product from the mixture of byproducts and residual starting material. Liquid/liquid extraction is a common separation step in this workup, which is then followed by purification of the product. There are two types of liquid/liquid extractions neutral and acid/base. ... 2 CH3CH2CH2CH2OH +2NaBr +H2S042CH3CH2CH2CH2Br +2H20 +Na2S04The 1-bromobutane is isolated from the reaction mixture by extraction with t-butyl methyl radical ether, an organic solvent in which 1-bromobutane is soluble and in which water system and sodium sulfate are insoluble. The extraction is accomplished by simply adding t-butyl methyl ether to the aqueous mixture and shaking it. Two layers allow result an organic layer and an aqueous layer. The t-butyl methyl ether is less dense than water and floats on top it is easily removed/drained away from the water layer and evaporated to leave the bromo product unacquainted(p) of inorganic substances, which reside in the aqueous layer. Partition Coefficient The extraction of a compound such as 1-butanol, which is slightly soluble in water as well as very soluble in ether, is an equilibrium process governed by the solubilities of the alcohol in the two solvents. The ratio of the solubilities is known as the diffusion coeeficient, also called the partition coefficient (k), and is an equilibirium constant with a certain value for a given substance, pair of solvents, and temperatureThe tightness of the solute in each solvent can be well correlated with the solubility of the solute in the slight solvent, a figure that is readily found in solubility tables in reference books. For substance C K = concentration of C in t-butyl methyl etherConcentration of C in watersolubility of C in t-butyl methyl ether (g/100mL)Solubility of C in water (g/100mL)Consider compound A that dissolves in t-butyl methyl ether to the finale of 12 g/100mLand dissolves in water to the extent of 6g/100mL.K = 1 2g/100mL
