    The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the

    Cyanide Fishing Recently‚ cyanide fishing for tropical and exotic species has become more prevalent in the South Pacific‚ causing harm to not only the marine life that is targeted‚ but their habitats as well. Many people in South East Asian countries rely solely on this fishing practice for income‚ in which they chase these tropical marine species and spray them with a cyanide solution to stun them and aid in their capture. These fish are then put into bags and exported to places like North America

    In the reaction mechanism‚ a carboxylic acid‚ m-toluic acid is used to synthesize N‚N-diethyl-m-toluamide‚ also know as DEET‚ through a nucleophilic acyl substitution reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a

    nanoparticles have unique properties which help in molecular diagnostics‚ in therapies‚ as well as in devices that are used in several medical procedures. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. The problem with the chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto them. To overcome this‚ the biological method provides a feasible alternative. The major biological systems involved in this are

    At the beginning of the lab‚ a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass‚ crucible‚ and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the

    Figure 6: Imatinib The first imatinib drug synthesis was done by Zimmermann (figure 7) in 1993‚ he used a chain of the reaction to reach to imatinib but the important part is that both guanidinium nitrate 7 and aminopyrimidine 8 are precipitated from the respective reaction mixtures by the addition of Figure 7: imatinib synthesis by Zimmermann insolubilizing solvents‚ so we got a condensation reaction between guanidinium salt 7 with enone “9” to form the aminopyrimidine “8” then “8” is

    crystals 18.287g Claim: Based on my calculations‚ the theoretical yield of Aluminum was 18.160g‚ and the actual yield was 18.287g. This gives a percent yield of 100.699%. Evidence/ Reasoning: By looking at the overall reaction involved in the lab‚ we can see that two moles of Aluminum are needed to react in the reaction‚ producing 2 moles of KAl(SO4)2 ·12H2O. This lets us know that however many moles of Aluminum there are in the original sample will be equal to
