  • The Grignard Synthesis of Triphenylmethanol

    3162 Words  | 13 Pages

    Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

    4-d]thiazoles and antimicrobial activity. INTRODUCTION Benzothiazoles are heterocyclic compounds with multiple application and although they have been known from long ago to be biologically active.1-3 Recently, Racane et al4 have described the synthesis of bis-subsituted amidinobenzothiazoles as potential anti-HIV agents. The condensation of dithio-oxamide with aromatic aldehyde was described by Ephraim.5 More recently, Johnson and Ketcham6 studied the reaction and established the structure of

  • Multistep Synthesis Chemistry Experiment

    Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product, tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

  • Essay about Acoustic Theory and Synthesis

    1158 Words  | 5 Pages

    Acoustic Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20,000Hz. As the cycles per second increases, the smaller the wavelengths become, therefore there is a higher frequency which will cause

  • Example Of The Hegelian Dialectic

    to controlling an outcome. A dialectical (Divided) method of argument by 19th Century German philosopher, G.W.F. Hegel. It is a method Comprised of Thesis, antithesis, and synthesis. The Hegelian Dialectic. A process where the contradiction between the Thesis and Antithesis resolves to a higher level of truth, the synthesis. Also knows as the Problem, Reaction, Solution. Its getting to the truth by exchange of logical arguments. When manipulating this method a person or group of people are swayed

  • Synthesis Of Dulcin Synthesis

    are some sugars that fulfill the need for sweeteners to be of low caloric content. Some of the sweeteners, such as Dulcin, are now considered to yield undesirable health effects with long term use. Dulcin is 250 times sweeter than table sugar. The synthesis of Dulcin was done in order to calculate the percent yield. The lesson of this experiment was to learn how to synthesize Dulcin from phenetidine and potassium cyanate (KOCN). During the experiment, Dulcin was synthezided in the presence of water

  • Synthesis Of Aspirin Synthesis

    Synthesis of Aspirin Erin Chase Arellano CHEM 12A ABSTRACT Acetylsalicylic or most commonly known as Aspirin is made through a combination of salicylic acid and acetic anhydride. It is use to relieve mild to moderate pain such as muscle pain, headaches and common cold and reduce fever. The objective of this experiment was to synthesize aspirin from salicylic acid and acetic anhydride. The purity of aspirin was tested using the ferric chloride test and % yield was also calculated. Below drawing

    photocleavable protecting group at the N3 position of thymidine, and duplex formation was achieved by photoradiation at 365 nm for 5 h (Iwase et al., 2003). NPOM-caged dT (X) introduced by the Deiters group is of particular interest. Figure 2.1.39 shows the synthesis of NPOM-caged thymidine phsophoramidite S.62 (Lusic et al. 2007) from nucleoside S.63 using reagent S.64, and DNA incorporating NPOM-caged thymdine was prepared by standard phosphoramidite chemistry and irradiated at 365 nm to afford active
