Isopentyl Acetate Synthesis Lab Report

1492 Words6 Pages

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 refluxing a carboxylic acid and an alcohol in the presence of a concentrated acid catalyst. The ester produced had a banana smell odor. The extraction of the crude product was conducted using sodium bicarbonate followed by distillation. The resulting product obtained was 4.491g of isopentyl Acetate, indicating a 70.02 percent yield. Based on the IR data, it was verified that the end products were as desired. The Isopentyl Acetate carbonyl bond …show more content…

Distillation usually works because organic compounds have boiling points which are different from each other. Usually a mixture of two compounds is placed in a round bottom flask. Heat is then applied to the mixture in the round bottom flask and as a result, the compound present in the mixture with the lower boiling point vaporizes first. The vapor then condenses in a condenser because the condenser has cool water to cool the vapor. The condensed vapor then travels into another flask at the other end of the distillation …show more content…

According to the IR spectra received for the sample of Isopentyl Acetate, there were three main signals present. The first of the three signals was present at a wavenumber of 2,961.70 cm^-1. A signal at this wavenumber indicates that there are hydrogen-carbon bonds present in this sample of Isopentyl Acetate. According to the structural formula of Isopentyl Acetate, carbon-hydrogen bonds are indeed present in its structure. The second of the three signals was present at a wavenumber of 1,742.88 cm^-1 . A signal at this wavenumber indicates that there is an ester group present in this sample of Isopentyl Acetate. According to the structural formula of Isopentyl Acetate, a carbonyl group is present in its structure. The final of the three signals was present at a wavenumber of 1,239.88 cm^-1 . A signal at this wavenumber indicates that there is a carbon-oxygen group present in this sample of Isopentyl

After adding the acetic acid and hydrobromic acid to the solution, and heating and recrystallizing the solution, the product triphenylmethyl bromide was created and had a mass of 0.103 g. The theoretical yield was calculated by determining the limiting reagent in the reaction. The triphenylmethanol was the limiting reagent in the reaction. The total amount of mass from the triphenylmethanol was converted to moles by using the molar mass of the triphenylmethanol. The amount of moles was then converted into grams to determine the theoretical yield, 0.125 g. The percent yield was then calculated by dividing the actual yield by the theoretical yield and multiplying the result by 100%. The percent yield was 82.4%.

The following lab period the solid was weighed (0.0483 g) and percent yield was calculated (65.5%) with the limiting reagent being tetraphenylcyclopentadienone. The melting point was determined. The first melting point was 204-204.9 °C and the second melting point was 215.6-215.9°C. Finally, an infrared spectroscopy was obtained for the

The unknowns were all basic except for the acetylsalicylic acid which was an acid and pseudoephedrine hydrochloride which was a neutral pH when tested. We tested our unknowns and found that both had a basic pH when tested. When we tested the ingredients for acetone solubility we found that most of the ingredients were acetone soluble except for acetaminophen, cornstarch, and sugar. For unknown A we

This supports the isolated product is majority made of the desired product and is largely pure. Mass spectrometry of the crude product shows the molecular ion peak is 162.1, which is the largest fragment in the mass spectrum (Figure 4) and corresponds to the molecular weight of methyl trans-cinnamate (Table 1). The base peak is 131, inferring the fragment lost is 31 m/z in size. This 31 m/z matches the OCH3 fragment of the ester, and would not result from a trans-cinnamic acid. This is evidence the product was successfully

Filtering, evaporating, centrifuging, and decanting something will only physically change it. Chromatography is used to separate different parts of a solution so that it can be identified. It can work because different substances have different attractions to things. Distillation can separate substances, such as salt water, as long as it has different boiling points. It can even be used to purify salt water but it is not cost efficient or energy efficient so it is not suitable for everyday use.

He described a cryoscopic method for synthesis and determination of molecular weight. He described the nature of glycosidic bond using changes in optical rotation and reducing power during methylation reaction of dextrins and ring conformation. He concluded that glucose was the only product of acid hydrolysis. However, he tried to prove the cyclic structure of dextrins [32, 33]. He also delivered the results of enzymatic hydrolysis, hydrolysis, and acetolysis with acetyl bromide pattern of dextrins.

The chemical and physical properties of a variety of chemicals work together to form a desired end product that is used commercially. Three chemicals that are used to form a bouncy ball in this experiment were; Polyvinyl Alcohol, Polyvinyl Acetate, and Borate. Polyvinyl Alcohol is a water-soluble polymer that is commercially used for paper and textiles products (Polyvinyl Alcohol PVA chemical Compound). Polyvinyl Alcohol is unique polymer, for it is only created with the dissolving of another polymer such as Polyvinyl Acetate, through hydrolysis (Polyvinyl Alcohol PVA chemical Compound).Polyvinyl Alcohol is an adhesive element. With the application of polyvinyl acetate that is formed from polyvinyl alcohol; is used as an adhesive in Elmer’s

14 vials were used for cotaining samples. When the distillation was proceeding at a moderate speed at about the wanted temperature, the receiver was replaced with a vial as the condensed vapour sample (V) and the thermometer was read. Half of the vial was filled with the sample. The stopper of the distillation flask was removed and using a dropper to collect the liquid.

In a simple distillation, the solution is brought to a boil and the vapours rise into a stillhead that directs them into a condenser. The vapour is condensed to the liquid phase and collected. This method works well for solutions that are composed of liquids with vastly different boiling points. However, if the liquids are similar in boiling points, fractional distillation is the preferred method of separation. In this technique, vapours are forced to pass through a fractional distillation column before reaching the stillhead.

The fractions in the fractional distillation such as N-hexane, isohexane, methyl cyclopentane have normal boiling point close to cyclohexane which makes the recovery of cyclohexane uneconomic and difficult. 2. Quantity of cyclohexane recovered is not enough to meet the current demand since the cyclohexane content of naphtha is about 5%- 15% by weight .3 Selection of Pathway to Cyclohexane (2) Hydrogenation of Benzene: C6H6 +3H2 →

The two primary hydroxyl functionalities provide excellent reactivity during both the esterification process and the subsequent crosslinking reaction. Although the cyclohexyl ring is completely saturated, the presence of labile beta hydrogens lowers the exterior durability of polyesters based on this diol. Generally, this diol is used for its excellent contribution to hardness and backbone rigidity. Ni et al [54] and Awasthi and Agrawal [56] can be considered in both works, 1,4 cyclohexanedimethanol was used for the synthesis of hydroxylated
