Purpose 1. To prepare a dry-packed sample of product mixture of ferrocene and Acetylferrocene 2. To separate and purify the components in the product mixture by column chromatography. 3. To check the purity of the components by thin-layer chromatography (TLC). 4. To calculate the yield of acetylferrocene and the percent recovery of unreacted ferrocene.

Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy

Gas Chromatography Analysis of Product Mixtures Gas Chromatography Guidelines‚ Handout. Introduction Gas chromatography is a technique used to analyze chemical compounds that can be vaporized and separated in a gas phase column. Once separated‚ the analyzed substance is passed through a detector and data is obtained. The samples that we are going to analyze are: the EtOAc from Simple distillation‚ the Fraction 1‚ Fraction 2‚ and Fraction 3 from the Fractional Distillation. Experimental Procedure

9.1 Orbitals and Theories of Chemical Bonding 1. Which one of the statements concerning valence bond (VB) and molecular orbital (MO) bond theories is correct? a) MO theory predicts that electrons are localized between pairs of atoms. b) In VB theory‚ bonding electrons are delocalized over the molecule. c) MO theory accurately describes bonding in O2 and NO‚ VB theory does not. d) VB theory can describe molecular bonding in excited states. e) MO theory is used to accurately predict

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their physical and chemical attributes‚ such as speed and weight. To easily picture the process‚ the example will pertain to a paper chromatography process in which the liquid is moving over the paper‚ separating

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase‚ which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds‚ causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention

CHEM 3152-003 Experiment 2: Fractional Distillation and Gas Chromatography Introduction: The purpose of this experiment was to separate a mixture of ethyl acetate (EtOAc) and toluene by using the method of fractional distillation and to analyze the fractions using gas chromatography (GC). ethyl acetate toluene Distillation is a method known as separating or purifying a liquid or mixture by vaporization and condensation. In a simple distillation‚ the liquids being separated boil below 150 0C

It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with

Standing over fifty-eight feet high is the Marble Column from the Temple of Artemis at Sardis‚ known as one of the seven wonders of the world. The marble column that stands tall at the Metropolitan Museum of Art is different from the rest found at the site of the temple because the capital is slightly smaller than the rest. This indicates that it did not belong to the outer colonnade. The columns at the Temple of Artemis are found to be ionic orders‚ being one of the three different types of orders
