antioxidant. Lycopene is found in various fruits and vegetables. The purpose of this experiment is the isolation of Lycopene from tomato paste. This is done using liquid/solid extraction and chromatography. Once the Lycopene is isolated‚ IR spectroscopy will determine its percentage actually obtained by chromatography. Procedure: A massed sample of 1.012g of tomato paste was placed in a 125mL Erlenmeyer flask. To the flask‚ 5mL of 50:50 hexane-acetone was added into the flask. After the 50:50

Ferrocene and Acetylferrocene will be separated using column chromatography. Column chromatography is a separation technique that is used among many disciplines including biology‚ biochemistry‚ microbiology and medicine. Many common antibiotics are purified by column chromatography.1 Column chromatography allows us to separate and collect individual compounds. In this experiment‚ lumen will be the stationary phase‚ and the more polar substance will be retained on the stationary phase longer

A paper chromatography was used to separate the pigments that make up chlorophyll to analyse‚ identify‚ and quantify the components‚ using paper (stationary phase – the part of the apparatus that does not move with the sample) and chromatography solvent that was 90% petroleum ether and 10% propanol (mobile

occurrence of an E1 mechanism in an alcohol dehydration reaction. Specifically this experiment involved the dehydration of 2-methylcylcohexanol by heating this alcohol in the presence of phosphoric acid and then to based on the results of the gas chromatography of the product to determine whether the alcohol exhibited the Evelyn Effect. The reaction taking place for both the Cis and the Trans isomers for Methylcyclohexanol are as follows: E1 Mechanism for Cis Methylcyclohexanol E1 Mechanism for

Chemical Equation: Fluorene (1) Fluorenone (2) Mp 114C mp 83C MW 166.22 MW 180.21 Introduction: Column chromatography was invented by Tswett in 1906 so that his study of the chemistry of chlorophyll could be facilitated. Tswett made significant advances in the method and demonstrated its applicability to the separation of many different kinds of mixtures. Column chromatography rapidly found application in all areas

Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained‚ but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is also used to describe some biological processes‚ especially in water treatment and sewage

Performance Liquid Chromatography but is also referred to as High Pressure Liquid Chromatography. It is used for separating mixtures either to analyse the mixture or to separate a required product from others in a reaction mixture. It can also be used to find the relative amounts of different components in a mixture. HPLC works along the same lines as paper chromatography. In paper chromatography a liquid (mobile phase) moves past a solid (stationary phase). In paper chromatography the stationary phase
