Abstract: 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.
Marissa De la Paz 29 October 2015 Landstrom T/R, 8am Experiment 13B: Phenyl Grignard Addition to Benzophenone The objective of this experiment is to first generate a Grignard reagent, then use that to synthesize triphenylmethanol. The Grignard reagent is necessary to create a new C—C bond. The formation of triphenylmethanol is broken down in several steps.
The recovered benzoic acid’s boiling point was within the accepted range of 120C; meaning that the recovered compound was
Abstract: The purpose of this experiment was identifying two compounds in an unknown mixture via liquid-liquid extraction and acid-base reactions. The compounds in the unknown mixture isolated by using recrystallization, and then their identity was determined by comparing the experimental melting point values with actual melting points. Unknown mixture 5 contained a carboxylic acid, 4-methylbanzoic acid, and a non-ionizable organic compound, 1,2-diphenylethane-1,2-dione.
Initial Results and Interpretation After testing whether the experiment ran the whole way on a TLC plate , it was determined that there were distinct differences among the co-spots and mixtures. Because of this, Para-fluorobenzaldehyde and acetophenone were chosen based on the results from the TLC plate as seen in figure three. The spots showed that the reaction ran to completion as the starting material, acetophenone and the final product had distinctly different RF values. As a result, this helped support the initial hypothesis that was made due to the
A 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.
To prepare for the lab, fill one 600 mL beaker ⅔ full with tap water (roughly 400 mL full) and place on a hot plate with a thermometer. This beaker’s temperature needs to stay constant at 60℃ so the hot plate settings may need to be adjusted throughout the lab. Next, fill the 1000 mL beaker ⅔ full with cool tap water (roughly 700mL full) and place a thermometer in it. Set this beaker aside and maintain a temperature of roughly 25℃. Place the test tube of benzoic acid/lauric acid in the 60℃ water on the hot plate and when the solid solution begins to melt place the thermometer that was in the water into the test tube.
In other lab procedures, benzoic acid is sometimes substituted for anisole in the Friedel-Craft acylation. However, the reason benzoic acid
This particular experiment is done as part of my Organic Chemistry course. I was really interseted to do this experiment and I worked out well in this experiment. This experiment was related to the preparation acetaminophen. Acetaminophen is an analgesic compound.
Objective: The purpose of this lab is to show the relationship between chemical decomposition and exothermic reactions, as well as applying the scientific method. This is shown through the construction and launching of popper rockets. Introduction: Crucial things to know are exothermic reactions, Scientific method and chemical decomposition. The scientific method is a series of steps used by scientists to solve a problem.
Bisphenol A, also known as BPA, is an industrial chemical which has been utilized for common plastics. BPA has been found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are used to produce containers that people store food and liquids in, such as water bottles. Epoxy resins are used to cover food cans, water supplies and etc. Research has shown that BPA is capable of leaking into foods and beverages that they are in.
Organic 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.
Purpose/Introduction The process of recrystallization is an important method of purifying a solid organic substance using a hot solution as a solvent. This method will allow the separation of impurities. We will analyze Benzoic Acid as it is dissolved and recrystallized in water and in a solvent of Methanol and water. Reaction/Summary
Abstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). 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.
