Methyl Benzoate
In this experiment, we used methyl benzoate from the last experiment with HNO3 and H2SO4 to synthesize methyl 3-nitrobenzoate. First we added methyl benzoate to 12 mL cooled conc. Sulfuric acid in a flask. In a separate flask, we made a solution of 4 mL conc. Sulfuric acid and 4 mL nitric acid and then added dropwise to the solution of methyl benzoate in an ice bath on a stir plate while maintaining the temperature of reaction between 5-15 °C. After the addition was complete we took the flask out of the ice bath and placed it back on the stir plate for about 20 minutes to complete the reaction. Then we poured the mixture in the beaker filled with ice and white solid started to precipitate out. After all the ice melted we used suction filtration

    The reaction mixture initially was a brown color which then turned a milky white color with the addition of bromobenzene and ether. The mixture turned back to a brown color with the addition of the remaining bromobenzene and ether added at a dropwise rate. The reaction vessel became warm at this point. The mixture then turned a reddish, pink color with the addition of 9.1g benzophenone in 100mL anhydrous ethyl ether. During the reflux the reaction mixture first turned a “pepto bismal” pink color then became a thick white liquid/solid. When the sulfuric acid was added the solution turned a yellow…

    Both reactants, the m-aminobenzoic acid and the 1-chloro-2,4-dinitrobenzene, were mixed together and were dissolved using dimethylformamide. The resultant solution was heated, mixed with deionized H2O and vacuum filtrated in order to separate our formed product form the solvent. This technique was further repeated after our product was washed with heated ethanol. The final product was m-(2,4-dinitroanilino) benzoic acid. The reaction mechanism for the overall reaction in question is as follows:…

    Dry, sublimed ferrocene (93 mg) was added to a reaction tube. Later, 0.35 mL of acetic anhydride and 0.1 mL of 85% phosphoric acid were also added. The reaction tube was capped using a septum, and a syringe needle was poked through. This was warmed over a steam bath and stirred for 10 minutes after it began to boil, forming a dark brown color. The tube was then cooled to room temperature, then further cooled in ice. A solution of 0.5mL was added, dropwise w/ mixing. 3M NaOH was added until the pH of the solution was neutral. The product was vacuum filtrated and pressed dry.…

    The electrophilic aromatic substitution reaction is the attack of a benzene ring on an electrophilic species resulting in the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product, methyl nitrobenzoate, was determined to be meta-substituted and the acetanilide reaction product, nitroacetanilide, was determined to be para-substituted.…

    The nitrating agent was prepared by slowly adding cold concentrated sulfuric acid (1.7 mL, 0.0319 mol) to cold concentrated nitric acid (0.6 mL, 0.0141 mol) in a 50 mL Erlenmeyer flask. The mixture was carefully swirled in an ice bath to ensure that the two concentrated acids were thoroughly mixed together. In a second 50 mL Erlenmeyer flask, acetanilide (1.0 g, 0.0074 mol) was dissolved in concentrated sulfuric acid (1.5 mL, 0.0281 mol) by having the acid slowly added to the solid while the mixture was swirled. Heating with a hot plate was also required to dissolve the acetanilide. When all of the solid had dissolved, the flask was cooled in an ice bath. The cold nitrating agent was added drop-wise to the cold acetanilide mixture. The flask was swirled after each addition of the nitrating…

    To study the affect of pH on a food preservative. Sodium benzoate changed into benzoic acid once the 3 M of HCl was added making it a pH of 2, making the solution acidic. The hydronium ion concentration was high enough that it gave a yield of benzoic acid, which, is very insoluble in water and it formed a precipitate in the solution. The end percent yield was 132.352%, this was due to a few flaws in the experiment. During the filtration process of the experiment the funnel was not working properly and not all the…

    MDMA (3,4-methylenedioxymethamphetamine) is a synthetic, psychoactive drug that is chemically similar to the stimulant methamphetamine and the hallucinogen mescaline. MDMA produces feelings of increased energy, euphoria, emotional warmth, and distortions in time, perception, and tactile experiences. The origin of the drug MDMA was patented in 1913 (patent #274.350) by the German chemical company Merck supposedly to be sold as a diet pill (the patent does not mention any intended use), the company decided against marketing the drug and had nothing more to do with it. The US army experimented with MDMA in 1953, possibly as truth serum. They have not revealed their reasons.…

    2. Usually LSD is taken by mouth. It is dissolved into a liquid and soaked into blotter paper, which is then cut into quarter inch sized doses. These are also called tabs, trips, or hits. Although it is less common, LSD powder can also be squeezed into tiny pills, called microdots, or placed into capsules. The liquid itself can be squeezed into the eye.…

    Oxybenzone

    • 667 Words
    • 3 Pages

    When I learned about the issues regarding oxybenzone, I was appalled. To think that something so potentially dangerous has been so widely accepted for so long is nothing short of troubling. My goal in this is as follows: create a campaign which will start a movement away from toxic suntan lotions and usher in a wave of sustainable products. This is important for a multitude of reasons. First of all, chemicals like oxybenzone are detrimental to coral reefs. Research has found that these chemicals can kill of juvenile coral, cause color bleaching, mutate their DNA, and even cause the prevention of new coral buds forming (sunscreen chemical, 2014). And without coral reefs, scientists are worried about what could occur to the oceanic ecosystem. Beyond the loss of its natural beauty, coral reefs are an important “mini-ecosystem.” Reefs provide shelter for some fish, rooms for algae to grow, and are a buzz of activity for hungry creatures. Without the reefs, scientists fear it could lead to species being wiped out. Second, there is the humanitarian aspect of oxybenzone. This is a known endocrine disruptor. Government tests have shown it to cause reduced…

    1,3,5-Trimethylbenzene

    By studying and calculating state variables from equations of state, such as the Peng-Robinson equation, the Clausius-Clapeyron equation, and the Antoine equation, one can see its dependence on thermodynamic properties of 1,3,5-Trimethylbenzene. After researching critical, triple, and melting point properties, other constants, and enthalpies of sublimation, fusion, and vaporization, many quantities were able to be calculated. The programs used to solve for these quantities were the Peng-Robinson Solver and Excel. These programs allowed for the calculations and comparisons of enthalpy versus temperature, specific heat versus temperature, the Joule-Thompson Coefficient versus temperature, pressure verses temperature, and pressure versus. molar volume. Having isotherms and isobars in these calculations allowed for the clear depiction of the relationship between two different variables and to see how the chemical compound 1,3,5-Trimethylbenzene, or Mesitylene, behaves thermodynamically.…

    Lysergic Acid Diethylamide (LSD) was created by chemist Albert Hofmann in Switzerland while attempting to create a blood stimulant. The drug was utilized for psychological experiments for many years and this even led to the military experimenting with it as a biological weapon in the 1960’s. During the 1960’s, as a result to the wide dispensing of the drug for experimental purposes, it wound up being the “…counterculture used the drug to escape the problems of society…” (LSD: A Short History). Due to its vivid hallucinations the drug was banned by the United States government in 1966.…
