This drug is found in a number of things ingested by people. It belongs to a group of nitrogen bases called purines. Because caffeine possesses these base-like properties‚ it is described as an alkaloid. They usually taste bitter and often are physiologically

Strategy is a plan of action which is designed to help achieve a long term goal. It is how the plan of action is decided that determines whether the strategy developed will be achieved.

3 STRATEGY In this section‚ we separate strategy into two components: the content of the strategy and the process of developing the strategy. The content describes how an organization will achieve its vision or strategic intent‚ i.e. it is a blueprint for winning. As such there is no one best strategy. A firm’s strategy ties together the different functional areas of the organization (e.g. marketing and finance) so that there is a consistency in action over time. It also drives implementation

Abstract This work describes the extraction of caffeine from tea leaves to determine its % caffeine. The extraction process selectively dissolves one or more compounds in a mixture into an appropriate solvent. In this experiment‚ it was visible in the process wherein the components of the tea leaves were dissolved in two solvents‚ water and dichloromethane (DCM)‚ with DCM used for multiple extractions. The organic layer was evaporated and the determined % caffeine was 0.12%. Furthermore‚ the purified

Strategy is the direction and scope of an organization over the long term‚ which achieves advantage in a changing environment through its configuration of resources and competences with the aim of fulfilling the stakeholder’s expectations.

collected‚ 5.758g of tea leaves contains 3.96% caffeine. After the purification process‚ 0.2279g of caffeine was obtained from 0.4948g crude extract with 46.06% yield. Melting point determination was used to characterize the caffeine yielded. However‚ the melting point range of the caffeine collected (190°C -215 °C) was lower than the melting point of the accepted value (238 °C) which may be due to experimental errors committed in the extraction and washing process.

Extraction 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 (CH₂Cl₂). Dichloromethane is less polar than water
