Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a

Synthesis of Isopentyl Acetate (Banana Oil) Using a Fischer Esterification Reaction Zhenshu Wang (Stan) TA: Aaron League September 23‚ 2012 Purpose: The purpose of the experiment was to perform the acid-catalyzed Fischer Esterification of acetic acid and isopentyl alcohol to form isopentyl acetate‚ or banana oil‚ which is used in flavor industries. The equilibrium of the reaction was changed by adding an excess amount of acetic acid. The reaction was refluxed and product was purified by extraction

Thus‚ acetyl anhydride was added to salicylic acid and the reaction synthesises acetylsalicylic acid‚ which contains an ester group. The addition of acetyl anhydride causes the phenolic group in salicylic acid to change to an acetyl group‚ R—OH R—OCOCH3 Hydroxyl group Acetyl group However‚ in order for

HDL cholesterol HDL is important because it removes free cholesterol from extra hepatic tissues. It also transfers cholesterol esters to VLDL or delivers them to the liver: There‚ HDL is degraded and cholesterol is released. These actions improve the ability to move cholesterol to sites where it is required. Additionally‚ the movement of free cholesterol and cholesterol esters help prevent cholesterol deposit and plaque buildup in blood
