  • Synthesis Of Aspirin Synthesis

    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 to create the powder form of aspirin, the process of crystallization was conducted and was run through vacuum filtration. After running through the help of an electronic instrument, the result that was achieved in this experiment was met due to the presence of esters in the graph in Figure 5; with a peak of 1297.89 at 1300-1100. There is also a match of 35.48 with ethyl salicylate. The objective, which is to create aspirin, has been completed due to the results shown by the data provided by an electronic instrument.A recommendation would be a more exact amount of reactants to be used. In this experiment, there was an excess of water and more acetic anhydride was used due to the salicylic acid not being able to dissolve at the amount of 0.3mL. Overall, this was a successful experiment where aspirin was synthesized properly. The melting point, using the meltemp, was at 146º-158 º. Introduction Aspirin is among the most fascinating and a versatile drug known to medicine and it…

  • Synthesis Of Trans-Cinnomine Synthesis

    Bromination of trans-cinnamic acid Purpose and Introduction The halogenation of of trans-cinnamic acid using pyridinium tribromide was connected in the organic solvent glacial acetic acid in order to verify and test which addition mechanism the reaction would follow. In the anti-addition mechanism, bromines attach themselves on opposite sides of the alkene functional group in a compound. In a syn-addition, the attach to the same side of the alkene. The reaction synthesis was completed by using a…

  • Synthesis Of Ethyl Cinnamate Synthesis Essay

    Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…

  • Synthesis Reflection

    As the third quarter comes to a close, it’s an important time to reflect on the quarter and the year as a whole. In the past two months, I have been able to learn how to write a whole new type of essay, the synthesis essay, and improve my reading comprehension skills through reading A Farewell to Arms and multiple choice practice sets. With these new skills and the knowledge I have gathered from the first semester of the class, I feel like I am well on my way to take the AP Language &…

  • Phenacetin Synthesis

    Phenacetin (C10H13NO2) can be synthesized from various organic compounds. The two primary compounds used for synthesis in this lab were Acetaminophen (C8H9NO2) and p-Phenetidine (C8H11NO). Both of these compounds have similar organic structures, however, Acetaminophen resulted in a more pure form of Phenacetin. Additionally, both of these compounds had to undergo specific chemical reactions, in order to form the same molecular structure as Phenacetin. Finally, these compounds had to be…

  • Si3n4 Synthesis

    A novel synthesis method to prepare Si3N4 nanowires from the amorphous silicon nitride (a-Si3N4) powder synthesized by low-temperature vapor-phase reaction method was investigated. Highly crystallized α-Si3N4 nanowires were synthesized from the heat-treatment of a-Si3N4 powder under ammonia atmosphere. The surface of the nanowires was smooth and clean without any attached particles. The thickness of the nanowires was in the range ~200–300 nm with the lengths of tens of micrometers. The…

  • Synthesis Of Aspirin

    Introduction The synthesis of aspirin is an organic experiment which salicylic acid and acetic acid is used to make aspirin. In addition, aspirin is purified and the percentage yield is measured. Salicylic acid is a compound used in some medical products. Aspirin is an acetylsalicylic acid and it does not upset the stomach like Salicylic acid because of its bitter taste. Aspirin passes through the stomach unchanged, then to the small intestines and finally absorbed in the bloodstream. Testing…

  • Synthesis Of The Mazeway

    as humanity strives to create meaning and significance from the emerging changes. Umair Haque writes: Social is significance. The real promise of social tools is societal, not just relational; is significance, not just attention. You’ve got to get the first right before you tackle the second — and that means not just investing in “gamification,” a Twitter account, or a Facebook group. It means thinking more carefully how to utilize those tools to get a tiny bit (or a heckuva lot) more…

  • Blackfish Synthesis

    Analysis and Synthesis The controversial practice of capture killer Whales train for entertainment purposes have risen an outrage to the public in 2013 by a documentary “Blackfish.” Since then, the growing uneasiness with the concept of that as humans, can we maintain a balance of respect for nature and desire capture and train spectacular things up close, for entertainment? The documentary “Blackfish” makes strong appeals to the audience focused on an orca performer Tilikum that killed…

  • Terpenoids Synthesis

    terpenoid biosynthesis. It has been suggested that this monophosphate pool regulates downstream carbon flux by inhibiting farnesyldiphosphate synthase (FPPS). By utilizing MPD from the archeabacterium Roseiflexus castenholzii, we can see how an increased isopentenyl (IP) pool affects downstream terpenoid biosynthesis. To do this, RcMPD was overexpressed in the background of Arabidopsis thaliana T-DNA insertion lines of a knockdown of IPK. These lines were tested for expression of MPD/IPK using…
