Those are important topics that should be familiar to you after Thursday's introduction.
In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings.
In order to determine how well this process had worked we employed: IR spectra analysis, column chromatography, and a little TLC.
This experiment is relevant in today's highly industrialized world. By utilizing many of the techniques we employ in this lab, a company can synthesize new types of materials or composites that could revolutionize an Want to read the rest of this paper?

As one recalls, polarity is a measure of the electronegativity of a compound determined by their placement in the periodic chart.
Specifically, in this lab we are talking about the difference in polarity between the atoms of oxygen and carbon. Ferrocene is relatively low to none in polarity.
Acetylferrocene, because of the carbonyl functional group, is more polar than the ferrocene. Moreover, diacetylferrocene, because of the 2: Both methods have an extremely polar stationary phase; specifically, silica or alumina gel is used.
Through this polar stationary phase, a mobile liquid phase is passed. Now, one can think of a polar stationary phase as a bully that waits in the high school halls for his hooligan friends.

The DMSO used in the experiment should be deaerated to minimize the psychological realities of characters in the novel life of pi the amount of oxygen in the reaction. Dec 05, · Instructional video for the University of Sheffield, department of chemistry, level 2 laboratory experiment ‘The synthesis and reactivity of ferrocene’.
Video . Ferrocene has extensive chemistry. An interesting reaction of ferrocene is the facile displacement of bromide from ferrocenyl bromide by a variety of nucle- ophiles.
In addition, it very readily undergoes Friedel—Crafts acylation and al- kylation reactions. In fact, ferrocene is times more reactive than benzene towards acetylation. Ferrocene Lab In the course of this synthetic sequence, the student will encounter operations such as sublimation, distillation, and execution of reaction under an inert atmosphere, all common techniques in synthetic chemistry.
