Benzocaine Synthesis
In the experiment, the primary initial chemical used was a 2.019 g mixture of benzocaine, and benzoic acid. Furthermore, the outcome of the experiment was 0.310 g of pure benzocaine, and 0.145 g of pure benzoic acid. Therefore, the percent recovery of the benzocaine and benzoic acid compounds was found to be 15.35%, and 7.18% respectively. In addition, later on in the process the melting points of the pure compounds were measured. The data of the benzocaine received from the lab was 93.2˚C, which is extremely close to the one reserved in literature (89˚C). Also, the data of the benzoic acid received from the lab was 131˚C, which is similar to the one retained in literature (122.41˚C). As a side note, the recovery of benzocaine required it to
Triphenylethanol Synthesis Lab Report
1804 Words | 8 PagesAbstract: In this experiment, triphenylmethanol was synthesized in two steps. First, the bromobenzene was reacted with dry magnesium turnings to produce Grignard reagent. Second, the Grignard reagent was reacted with methyl benzoate and concentrated sulfuric acid to produce an alcohol. The end result of the experiment was not very successful because only 17% yield of final product triphenylmethanol was recovered, and the final product was impure based on the melting point and the IR spectrum results.

Camphor Reduction Lab Report
1420 Words | 6 PagesA mixture of 0.25 g of camphor (1.64 mmol), 1.5 mL of methanol, and 0.25 g of sodium borohydride (6.60 mmol, NaBH4) was boiled for 2 minutes. Moreover, the addition of 10 mL of ice deionized water resulted in a white solid after the organic solution was vacuum filtered. The organic solid was dissolved in 10 mL of dichloromethane (CH2Cl2) and small amounts of anhydrous sodium sulfate (NaSO4) to dry. The organic solution was decanted and evaporated for melting point (203.3-203.8 °C), NMR, and IR spectroscopy. Product formation and heats of formation (borneol = -1.203675E6 kJ/mol, isoborneol = -1.203687E6 kJ/mol) were analyzed.

Two Components Of An Unknown Mixture Lab Report
760 Words | 4 PagesThe purpose of this experiment was to identify the two components of an unknown mixture through diverse experimental techniques such as recrystallization, extraction, melting point, and acid-base reactions. From this, the group to which these two compounds belong to had to be determined. These groups are: Carboxylic Acids, phenols, and neutrals. By determining the melting points of the two unknown compounds, these values were compared to the values of melting points in the chart and the proper compound was selected. For the case of this experiment, the unknown mixture contained, 4-methylbenzoic acid.

Unknown White Compound Lab Report
1367 Words | 6 PagesAbstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
Heptane Lab Report
963 Words | 4 PagesIt is possible that the discrepancy of the molecular weight of both acetone and the unknown volatile liquid was caused by the deviation of mass in each trial. During the trial of the experiment aluminum foil was used as a cap for the Erlenmeyer flask and by using a pin, a hole was made into the cap to insure that the gas vapors would escape during the heating process, later the Erlenmeyer flask was measured after the heating process when the gas was fully condensed; however, this procedure effected the results collected. With the usage of the aluminum foil it had resulted the presence of excess moisture build up from the water bath which then had increased the mass of the gas that had been condensed due to it being measure with both the foil and elastic band. Since, the Erlenmeyer flask was left behind with the water moisture contained in the foil; therefore, it had affected the final mass of the condensed vapor inside the flask. Although the procedure was effective and adequate results were obtained, there are some improvements that can be made towards the experiment to make it exceptional.

Recrystallization Of Acetanilide Essay
920 Words | 4 PagesThe melting point range for the crude product was 113-115.3℃. the melting point range for the purified product was also 113-116℃. This melting point range was almost perfect to that of the theoretical melting point which is 113-115℃ proving that the product was in fact created. When looking at the percent yield of the crude acetanilide, there was an 81% yield which was a very good yield because the average percent yield is between 80-90%. The percent recovery of the acetanilide was 88% which is also very good because much of the product was recovered meaning that the product was in fact

Organic Chemistry Experiment 3: Chromic Acid Oxidation Reaction
702 Words | 3 PagesOrganic chemistry II Experiment 3: chromic acid oxidation reaction Introduction: Camphor is very compact and its molecular structure is symmetrical which gives it the property to change directly from a solid to vapour when heated. Therefore, camphor can easily be purified by sublimation technique. Sublimation is a phase change in which a solid phase passes directly into the vapour without going through an intermediate liquid phase. Solids which have vapour pressure below melting points can be purified by 1) heating the solid to sublime it 2) condensing the vapour on a cold surface 3) scraping off the condensed solid. Sublimation is not a very accurate method as recrystallization or chromatography.
Benzoic Acid Lab Report

With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
