In the formation of acetylsalicylic acid (Aspirin)‚ salicylic acid and acetic anhydride were made to react in the presence of an acid catalyst‚ namely sulfuric acid. In the formation of methyl salicylate (oil of wintergreen)‚ salicylic acid and methanol were reacted together in the presence of the same acid catalyst‚ sulfuric acid

Effects to the water quality Oils consist of a complex mixture of hydrogen and carbon which is used for fuel‚ lubrication‚ plastics manufacturing‚ and many other purposes. These petroleum products get into water mainly by means of accidental spills from ships‚ tanker trucks‚ pipelines‚ and leaky underground storage tanks Petroleum products affect surface water‚ impairing water quality with hydrocarbons‚ salts‚ nutrients‚ a host of organic compounds‚ and various heavy metals.

Name of the Experiment: Simple Distillation (Semimicroscale Procedure.) Abstract: Distillation is a method of process of separating 1:1 mixture based on differences in their volatilities in a boiling liquid mixture. Distillation is done with the use of simple distillation apparatus shown in Figure 1. In this experiment‚ simple distillation process was used to determine the identities of the unknown compounds in the solution through the obtained boiling points. The list of probable unknown volatile

A portion of the dimer (0.0305 g‚ 0.0514mmol) was quantitatively dissolved in 25ml of toluene. The solution was left for 60min until colorless. The UV-Vis spectra was recorded for the colorless sample. The solution was irradiated using a lamp resulting in a purple solution and the UV-Vis spectrum was retaken. UV (): 524.92nm ε colourless (45

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase
