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 the

They are many Criminal Theories from Psychological theories‚ social theories‚ deterrence theories and a few more but let focus on‚ Choice Theory‚ known as‚ rational choice theory. People will engage in delinquents and criminal behavior after weighting consequences and benefits of their actions. According to this review in‚ motivated people‚ after consideration‚ will commit crime if they believe that it will provide immediate benefits without the threat of long-term risk (David‚ et al‚ 2006).

moles of the purified aspirin product after extraction was 7.77 x 10-4 as shown in Equation 4. These two moles calculated a chemical yield of 54.3% as shown in Equation 5. The melting point of the pure aspirin product was ranged at 117.8-125.2C as shown in Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed

Why did Mrs. Endo die? On the 17th of January 1995‚ a great earthquake struck the Japanese city of Kobe at 5:40 am. Over 80% of the quake victims died together with Mrs Endo‚ her husband‚ however‚ did not! There are numerous reasons why‚ the aim of this essay is to explain them to you. The earthquake started due to the fact that Kobe is situated among 3 of the Earth’s tectonic plates (The Eurasian‚ the Pacific and the Philippine plates).Stress had been strengthening in the rocks of the Philippine

Synthesis of Aspirin Ling Tecson Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order

result in criminal charges being filed. If carried out by individuals unskilled at chemistry they could result in serious bodily harm. MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which can be followed by an amateur with very little knowledge of chemistry. However‚ people with less than 2 years of college chemistry experience would probably not be capable of sucessfully synthesizing MDMA‚ and would either
