Reuven Ilyayev Lab Instructor: Maciej Domaradzki Labs 3 & 4 09/19/11 Objective: In steam distillation lab (lab 3)‚ we must obtain pure Eugenol from cloves through the process of steam distillation. In the crystallization lab (lab 4) part 1‚ we must acquire the best possible pure crystallization of acetylsalicylic acid from aspirin and in part 2 we must obtain a similar pure crystallization of benzil from an impure mixture of benzil. Materials: In lab 3‚ we used 75 g of cloves from
Premium Distillation Solvent Ethanol
This process allows to isolate or concentrate the desired analyte or to separate it from species that would interfere in the analysis. The most used process is the extraction of an aqueous solution with an organic solvent. Diethylether‚ toluene‚ and hexane are common solvents that are immiscible with and less dense than water. They form a separate phase that floats on top of the aqueous phase. Chloroform and carbon tetrachloride are common solvents that are denser than water. In the two-phase mixture
