Cochin, also known as Kochi, is a major port city located in the Indian state of Kerala. The city has a strong industrial base, with a number of chemical companies operating in the area. These companies play a vital role in the economy of Cochin, as they manufacture a wide range of products that are used in a variety of industries.
One of the major chemical companies operating in Cochin is FACT, or the Fertilizers and Chemicals Travancore Limited. Established in 1943, FACT is a public sector company that produces fertilizers and chemicals for agricultural and industrial use. The company has two manufacturing units in Cochin, and its products are sold both nationally and internationally.
Another well-known chemical company in Cochin is Kochi Refineries Limited (KRL). KRL is a subsidiary of Bharat Petroleum Corporation Limited (BPCL), and it was the first refinery in India to be set up in the private sector. The company produces a wide range of products, including gasoline, diesel, kerosene, and LPG, which are sold to customers in the domestic and international markets.
In addition to these larger chemical companies, there are also several smaller firms operating in Cochin. These companies produce a variety of chemicals for use in industries such as pharmaceuticals, textiles, and plastics. These smaller companies often specialize in the production of specific chemicals, and they play an important role in the local economy.
Overall, the chemical industry in Cochin is an important contributor to the city's economy. These companies provide employment opportunities for local residents and generate significant revenues for the region. In addition, the chemicals produced in Cochin are used in a variety of industries, which helps to drive economic growth and development.
Methyl Acetate Hydrolysis Reaction Lab Report
This indicated that the carbonyl from acetic acid had been utilized. It is also found naturally in plants, tress, volcanic gases, and forest fires and as a by product of the breakdown of body fat. Although these esters can undergo many different important reactions, this lab is particularly interested in the hydrolysis of esters into carboxylic acids and alcohols. Carbonyl Also, in this experiment a process of distillation was used where the banana oil was separated from the crude ester mixture. All the synthesized aminocellulose tosylates were soluble in water, and their transparent films formed complexes with Cu2+ ions, and used to immobilize glucose oxidase enzyme86, scheme 34. The iconic aspect of creating a synthesis of this chemical compound is its strong odor of bananas. Â 5mL of saturated sodium chloride was added to the contents of the separatory funnel.

Isopentyl Acetate Synthesis Lab Report
Based on the experiment that was conducted the synthesis of isopentyl acetate from a carboxylic acid and an alcohol could be done by a Fisher Esterification reaction, and the percent yield of the product is about 61. Procedure First, a reflux apparatus was set up with a round bottom flask at the bottom. It is also necessary to utilize organic chemistry techniques, such as distillation, and analyze infrared and gas chromatography spectrums. Amines will produce medium and broad signals at a frequency of 3500cm-1. Theobromine is also known as a diuretic, which promotes the removal of excess fluids accumulated in the body from edema, or the flushing of excess salts through the increase production of urine Judelson, 2013. By this method, esters are produced by refluxing a carboxylic acid and an alcohol in the presence of a concentrated acid catalyst.

Isopentyl Acetate Synthesis Lab Report Essay Essay
This is because the ester formed is the equatorial position, which makes the compound more stable than cis-4-tert-butylcyclohexanol. The continuous process involves the continuous flow of the reactants through a series of reaction vessels, where the reaction takes place. This was done through a fischer esterification reaction with acetic acid and isopentyl alcohol using sulfuric acid as a catalyst. The isopentyl acetate was synthesized first by refluxing, than by distilling. The percent yield was 70 percent. Remember, you used an excess of glacial acetic acid.

Another way to upset the equilibrium in favor of esterification would be to remove the water produced in the reaction. This reverse reaction is the reasoning behind why esters are not used to produce perfumes. According to the structural formula of Isopentyl Acetate, a carbonyl group is present in its structure. The water layer was then discarded with the mixture from the round bottom flask was retained in the flask. Isoamyl acetate, also called banana oil, is specific for delivering a sweet and fruity odor that attracts fruit flies and other insects. Pigments choose the organic layer over the tomato paste with water, which allowed for their extraction. Isopentyl acetate is prepared though fisher esterification of acetic acid with isopentyl alcohol.

Cutting down or adding the number of carbons affects the smell, such as if we rid isopentyl acetate of one carbon and end up with isobutyl acetate whose smell resembles that of a raspberry. Typically, only primary and secondary alcohols are used in the Fisher method since tertiary alcohols are prone to elimination. Attach a drying tube with a small plug of cotton inside of it on top of the water condenser odor control Preparation 1. In this experiment you will prepare two esters of o-hydroxybenzoic acid, more commonly known as salicylic acid. The solution also produced a smell similar to banana. The resulting product obtained was 4.

Synthesis of Isopentyl Acetate Lab Report
Synthesis of Isopentyl Acetate In modern times, the cosmetic industry has employed the use of esters in the production of self-care and vanity products such as perfumes and make-ups. The percent yield of the isopentyl acetate was 61. A signal at this wavenumber indicates that there is an ester group present in this sample of Isopentyl Acetate. Our academic experts are ready and waiting to assist with any writing project you may have. A clean, dry, empty graduated cylinder was weighed, and its weight was recorded. Add 5% sodium bicarbonate until the bubbles cease if it has not ceased after 3 mL 5.

Fischer Esterification of Isopentyl Acetate
Turn on the water, the heat, and the stirrer in that order 2. In a publish literature describing the hydrolysis of Chirality of Ethyl-3-Hydroxybutanoate Generated from a Biological Pathway Introduction: This experiment was preformed to study the chiral selectivity of the reduction of the ketone portion of Ethyl acetate to a secondary alcohol. It is also found naturally in plants, tress, volcanic gases, and forest fires and as a by product of the breakdown of body fat. The reaction mechanism involves the protonation of the carbonyl of the acetic acid, followed by the nucleophilic attack on the acetic acid, by the isopentyl alcohol. Low molecular weight esters tend to have characteristic flavors and pleasant odors that are most often associated with essential oils, even though essential oils are a complex mixture.

The sulfuric acid was used as a catalyst in the reaction. Procedure First, a reflux apparatus was set up with a round bottom flask at the bottom. Since sodium carbonate is a base, it is used in the extraction of acetic acid because it turns acetic acid into a conjugate base or sodium acetate which is more soluble in water. For the duration of reflux, the solution turned from a yellow color to a deep amber color. The technique used for this reaction is reflux. The amount will be the baseline for activities C and D.

This may be due to molecular nature of inulin and its interaction with water and other solute molecules. These scents are often produced synthetically by the food industry as additives for fruity flavors and scents in foods, such as candies. Esters are derived from carboxylic acids. This experiment was successful because the smell of bananas was achieved along with the percent yield attained of 61. This is because the pheromones produced by these insects are composed of isoamyl acetate.

Esters occur naturally in flowers, fruits, and spices. The purification was conducted using distillation. Nearly all world production of acetone is via cumene peroxidation, as a coproduct with phenol. The water could then be used in the final step to deprotonate the hydrogen connected to the oxygen with a positive charge resulting in the formation of Isopentyl Acetate. Overall, the synthesis of isopentyl acetate is a useful and widely employed process that is used in the production of flavors, fragrances, and various industrial materials.
