Extraction Of Caffeine From Tea - 1878 Words

EXTRACTION OF CAFFEINE FROM TEA Abstract The method used to separate the organic compound from a mixture of compound is the extraction. It is done by the dissolving of one or more compounds in a good solvent. The solvent which was used in this experiment was 15 ml of dichloromethane into 125ml of water. Caffeine was extracted from 9.19 g of TAZO Awake English Breakfast. Caffeine is soluble in water in 2.2 g/ml at 20 C; it is more soluble than dichloromethane which has 10.2g/ml at 20 C, and the method used for the extraction was the liquid-liquid extraction method, followed by evaporation. The objective of going through all these steps was to be able to obtain caffeine from tea and to see how pure or how the caffeine was not pure in comparing the standard values of Melt Point and RF values of the result of the experiment. Introduction It is well known that tea is one of the greatest frequently used caffeinated drinks in the world. The caffeine (C8H10N4O2) which was extracted from the tea was harsh and white. Caffeine is known as being a great stimulant which is mostly used by the majority of people, and caffeine has a power in people’s organism. It creates many different kinds of problems, such respiratory problems, heart rate problems, anxiety and insomnia problems. On the other hand, caffeine has some good effects for people, such as improving alertness, learning capacity and exercise performance (NCBI, 2013). Tea Also contains other components such asShow MoreRelatedExtraction of Caffeine from Tea Leaves1151 Words   |  5 PagesExtraction of Caffeine from Tea Leaves Introduction Caffeine is soluble in boiling water and as a result it is easily extracted from tea bags by steeping in hot water. This process leaves behind the water insoluble portions of the tea bag. However, water extracts more than just caffeine, so a final separation is done with an organic solvent that will dissolve primarily caffeine. The organic solvent used in this experiment is Dichloromethane (CHâ‚‚Clâ‚‚). Dichloromethane is less polar than waterRead MoreUsing Solid Liquid Extraction Of Caffeine From Tea Leaves867 Words   |  4 PagesThe purpose of this experiment was to use solid-liquid extraction to isolate a crude sample of caffeine from tea leaves and then subsequently purify the isolated sample via sublimation. The two solvents used in the extraction were water and dichloromethane. In addition to caffeine, tea leaves also contain other compounds that must be dealt with including cellulose, proteins/pigments, tannins, and saponins. Cellulose is not soluble in water as a result of its high molecular weight and thereby doesRead MoreEffectiveness Of An Extraction Process And Purification Process955 Words   |  4 Pageseffectiveness of an extraction process and purification process by sublimation is observed and used to selectively separate caffeine from teabags. In the first part of the experiment, water soluble materials, including caffeine, within the teabags are extracted into hot water because the solubility of caffeine in water increases as temperature increases. This is due to the concept that increasing kinetic energy through increasing temperature will allow the molecules in the solute to break apart from the intermolecularRead MoreEssay Separation of Benzoic Acid and Acetanilide1243 Words   |  5 PagesReport 13 October 2011 Table of Contents Separation of Benzoic Acid and Acetanilide 3 Extraction and Purification of Caffeine from Tea 4 Extraction of Trimyristin from Nutmeg 5 Conversion of t-butanol to t-butyl chloride 6 Appendix 7 Calculations 8 Literature and Experimental Values of Benzoic Acid and Acetanilide 9 Experimental Caffeine IR 10 Literature Caffeine IR 11 Experimental Trimyristin IR 12 Literature Trimyristin IR 13 Experimental Tert-Read MoreCaffeine Lab Report769 Words   |  4 Pagesthe experiment caffeine [C8H10N4O2], is based on a series of procedures. Firstly, it is important to examine the structure of caffeine which is an alkaloid. Typically alkaloids are nitrogen based and found in plants, caffeine itself is composed of a purine ring with functional groups of a amide, amine and alkene respectively. Furthermore, Caffeine includeds a lone pair on the nitrogen atom asserting several functional properties(Zhao et al. 206). Under examination of the caffeine structure severalRead MoreEssay Acid Base Extraction1511 Words   |  7 Pages Acid Base Extraction The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities. Introduction: Acid/base extraction involves carrying out simple acid/base reactions in order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic substancesRead MoreThe Role of Caffeine in Society Essay970 Words   |  4 PagesCaffeine plays an enormous role in society today, from coffee to cokes to candy bars. Companies have made billions off the desire for that extra kick. Caffeine is the most widely consumed behaviorally active substance in the world making it one of the world’s most popular drugs. It’s known for the ability to stimulate the brain and central nervous system. The Chemical structure of caffeine is C8H10N4O2. Before the popular use of caffeine one can assume that people were sleepier, and less alert.

The majority of people consume caffeine as part of their everyday lives. It helps us feel â€Å"alive† in the morning, by giving us the energy and focus that we need throughout the day. Caffeine has many benefits, some of which most people do not even know about. For a drug so commonly used, little attention is paid to the dangerous properties of caffeine products.
