Elaboration Of Instant Coffee And The Extraction Process Essay

14 mL of 9 M H2SO4 was added to the separatory funnel and the mixture was shaken. The layers were given a small amount of time to separate. The remaining n-butyl alcohol was extracted by the H2SO4 solution therefore, there was only one organic top layer. The lower aqueous layer was drained and discarded. 14 mL of H2O was added to the separatory funnel. A stopper was placed on the separatory funnel and it was shaken while being vented occasionally. The layers separated and the lower layer which contained the n-butyl bromide was drained into a smaller beaker. The aqueous layer was then discarded after ensuring that the correct layer had been saved by completing the "water drop test" (adding a drop of water to the drained liquid and if the water dissolves, it confirms that it is an aqueous layer). The alkyl halide was then returned to the separatory funnel. 14 mL of saturated aqeous sodium bicarbonate was added a little at a time while the separatory funnel was being swirled. A stopper was placed on the funnel and it was shaken for 1 minute while being vented frequently to relieve any pressure that was being produced. The lower alkyl halide layer was drained into a dry Erlenmeyer flask and 1.0 g of anhydrous calcium chloride was added to dry the solution. A stopper was placed on the Erlenmeyer flask and the contents were swirled until the liquid was clear. For the distillation

The fictional story “Drinking Coffee Elsewhere,” by American author ZZ Packer, is about an African American college student that encounters many behavioral issues throughout her freshman year at Yale University. The main character of the story, Dina, is an insecure, immature, and selfish young adult who has gone through tough moments in her life. Dina is the narrator of the story; it is told through her eyes. After Dina mother’s death, her attitude gets worse and she tries to be isolated from everyone as much as she can. During Yale orientation, Dina introduced herself violently to the class, the dean of the college gets worried about her behavior, and she is assigned to attend counseling sessions with a psychologist. Dina then meets one of her poetry classmates accidently; after Heidi knocks at Dina’s door, they share time together, and become good friends. The main character sometimes may appear aggressive and uncaring do to the fact that she is dealing with self-identity problems. In the end, she suddenly appears upset and starts making many mistakes that end up costing her friendship. After losing the only friend she has, she wishes to go back and fix the mistakes she made.

Filtering coarsely ground coffee beans after mixing it in cold water after several hours, results in cold coffee brew.

The alluring aroma of freshly brewed java is both tantalizing and calming to the senses, so much so, that most individuals are unable to fathom a morning or a day without a cup of fragrant, hot coffee in hand. Coffee is one of life’s little indulgences that have become a necessity for some, who find it increasing difficult to live without, as a result, Keurig created an innovative, and unique form of preparation. The Keurig machine makes it possible for a single serving of coffee, tea, hot chocolate, or water without the need to clean the machine in between its use. It eliminates the “stale-tasting” waste that results from the remnants of old coffee, which no coffee drinker desires, and it eradicates the need to clean the pot or brew basket, all this in less than a minute!

Coffee is then sent to roasting facilities where it is blended. By “manipulating the composition of the blend, roasters

In this experiment, distillations were done. This is a technique that utilizes the differing boiling points of two or more compounds in a mixture in order to separate the compounds from the mixture. The way fractional distillation works is that the initial mixture is boiled up to the point of the lower boiling point compound; this compound then evaporates. This compound is then

Every human being having to start the morning with a cup of coffee or tea with hot and delicious breakfast, and mid-morning or afternoon. The great hot coffee or tea is sharing with family, friends and co-workers. Some people are like to drink coffees or teas as taste bold to medium and mild with any types of products. In 19th centuries to now, there are so many food businesses open in the market such as coffee stores, food restaurants, retail grocery stores and food industries. There are different country’s coffees or teas with flavors find in the coffee or cafe stores. The coffee businesses are open such as Starbucks coffee, Dunkin Donut, McDonald, Panera, Caribou café etc. All these coffee businesses have the own corporate stores,

There are a number of significant competitive barriers within the coffee bean and coffee grind industry. While virtually any firm can purchase the raw materials or even the finished product in the form of ground coffee, the packaging and distribution of the product is a much more sophisticated endeavor. The most significant

Essentially the warm water will run through the coffee beans and extract its properties. The flavor of the coffee beans would disperse into the water. The water would change color and smell like the coffee beans as these properties are drained from the coffee beans.

100 mL of whole milk was measured in 250 mL flask and put on a hot plate in the hood. A thermostat was used to make sure that the milk did not go over 40 ͦC. When the Milk reached 39.2 ͦC, 11.0 mL of 10% acetate acid solution was added and stirred form 1 minute. Three coffee filters were nested into one another and used with a funnel to filter the solution into a clean 250 mL flask. A vacuum filter was set up while the solution was

The purpose of this experiment was to separate a two component mixture using fractional distillation. Distillation is a process of vaporization than condensation of a substance, used primarily to separate substances from a mixture when there are different boiling points. Fractional distillation is when the mixture has multiple substances with similar boiling points, and a fractional column is used to create multiple vaporization/condensation cycles. Fractional distillation is important when two or more substances need to be separated, but they have similar boiling points.

An abundance of people like to enjoy a steaming cup of coffee in the morning, myself included. There are various ways one could make a cup of coffee. Personally, I like to use a Keurig coffee machine. The quick process makes it easy for me to savor my morning cup of coffee.

For each cup of fresh coffee, coffee beans should be grounded just before brewing. Therefore, for each customer, the coffee is treated as fresh produce. Coffee should not be overexposed to oxygen, light, heat and moisture. In order to save customer from the time of waiting for the clerk to grind their coffee, customers can grind their own coffee beans in the store. Instead of walking in to wait in line, customers can help the process by grinding their own coffee beans before getting in line. The grinder will be pre-set to grind the coffee beans to the perfect texture of fineness.

Once cooled, the mixture was then transferred to a separatory funnel using the funnel while avoiding adding the boiling chip. 10 ml of water was then added to the mixture. The mixture was gently shaken and the phases were allowed to separate. The funnel was then unstopped and the lower aqueous phase was drained into a beaker. 5 ml of 5% aqueous NaHCO3 was added and then shaken gently. A great deal of caution was taken into consideration because of the production of carbon dioxide gas which caused pressure to develop inside the funnel. The pressure needed to be released so the funnel was vented frequently. The phases were allowed to separate and the lower aqueous phases was drained into the beaker. After draining, 5 ml of saturated NaCl was added to the funnel and then shaken gently. Once again, the phases were allowed to separate and the lower aqueous phase was drained into a beaker. An ester product was produced and was transferred into a 25 ml Erlenmeyer flask. This organic product was then dried over anhydrous Na2SO4 to trap small amounts of water in its crystal lattices thus removing it from the product. Finally the ester was decanted, so that the drying agent was excluded from the final product.

Imaging if there was no more coffee in this world, how would you feel? Nowadays, coffee becomes an important part of people’s life. People who often work overtime, they drink coffee because caffeine can make you awake; people who have to wake up early in the morning, they drink coffee because instead of making breakfast, coffee is more convenient; people drink coffee during the free time, because it also tastes good.
