Extraction of Caffeine from Tea Leaves Jaybee Balilea‚ Sharmaine Baysic‚ and Maria Anjelette Patricia Belen 3BIO7‚ Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Extraction is a technique for isolating and purifying organic substances. In this technique‚ a solution is combined thoroughly with a second solvent that is immiscible with the first solvent. The solute is extracted from one solvent into the other because it is more soluble in the second solvent

TITANIUM EXTRACTION ASSIGNMENT 1 1.TiO2+Cl2-----------------TiCl4+O2 2.Why is an atmosphere of argon used for this reaction ? The titanium (iv) chloride is added to a reactor in which very pure sodium has been heated to about 5500c -everything being under an innert argon atmosphere.During this reaction the temperature increases to about 10000 c . The reaction is carried out in an argon atmosphere to prevent magnessium and sodium from reacting with oxygen in the air. 3.Another gas used instead of

algorithms are implemented using C++ programming language‚ some algorithms use available functions of ArcObjects in ArcGIS. Based on VB .NET and ArcObjects programming‚ a graphical user’s interface has been developed to integrate and organize shoreline extraction routines into a software package. This product represents the first comprehensive software tool dedicated for extracting shorelines from remotely sensed data. Radarsat SAR image‚ QuickBird multispectral image‚ and airborne LiDAR data have been used

EXTRACTION OF TRIMYRISTIN FROM NUTMEG: Paul I. PURPOSE: The purpose of this experiment was to illustrate the extraction of a solid natural product from its natural source by partition with the aid of an organic solvent. Extraction is the process by which a compound or mixtures of‚ is transferred by separation from one phase into another. In this case‚ the major triglyceride contains a single fatty acid identified as myristic acid. It is a substituent

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example
