Discussion In this experiment, the synthesis of p-di-tert-butyl benzene was achieved by using the Friedel-crafts Alkylation. How the purposes were or were not accomplished For this experiment, 0. 02356 grams of p-di-tertbutyl benzene were recovered. The theoretical percent yield was 0. 616 grams of the product. This gives a 38. 2% yield. The product obtained…

For my final project the first compound I synthesized was Dulcin. Dulcin is an artificial sweetening agent that is 200 times as sweet as sucrose. It is also, the second synthetic sweeter that was discovered. The first synthetic sweetener, saccharin, was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately…

The body uses cholesterol to make vitamin D and various hormones, such as estrogen, testosterone, and cortical. The body can produce all the cholesterol that it is needs, but it also obtains cholesterol from food. Lieberman-Bernhard test: The Lieberman-Bernhard or acetic anhydride test is used for the determination of cholesterol. The formation of a green…

Abstraction This experiment was conducted to synthesise methyl benzoate signifier benzoic acid and methyl alcohol by utilizing the Fischer esterification method. The Fischer exterification technique is utilized in the academic and industrial scenes due to the simplified synthesis and safety parametric quantities of the overall reaction. Both benzoic acid and methyl alcohol are comparatively inexpensive…

The objective of the experiment was to produce two azo dyes: p-nitrobenzene azoresorcinol and methyl orange. The initial step involved mixing p-nitroaniline and resorcinol to create p-nitrobenzene azoresorcinol. In order to form the diazonium salt, we combined a solution containing p-nitroaniline dissolved in hydrochloric acid and water with a sodium nitrite solution. Subsequently, the resulting…

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

The organic compounds that are most common in foods that come from plants are carbohydrates. However, the organic compounds that are most common in animal meat are proteins. The original colors of the food substances did affect our test results. For example, if the substance was yellow, such as apple juice, and we were trying…
