Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

A principle concern in the fracking debate lies over the content of the “fracking fluid.” This fluid is used to increase pressure in shale formations and cause fractures that increase permeability and allow greater access and capture of liquid natural gas or other hydrocarbon products that would be otherwise inaccessible or require numerous more wells be drilled (He‚ Li‚ Liu‚ Barbot‚ Vidic‚ 2014). This fluid consists of water and chemical additives such as‚ “ friction reducers to optimize flow characteristics

environment have resulted in numerous ripple effects including the acidification of the ocean. The ocean is a complex mixture of chemicals primarily consisting of water‚ sodium chloride and trace elements of magnesium‚ sulfur‚ potassium‚ calcium and bromine. Calcium is the most important constituent as it is important in sustaining marine life and plays a role in the chemical balance of the ocean. The acidification of the ocean‚ precipitated by global warming‚ is causing a change in the chemical interactions

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

separate these two compounds column chromatography can be used to exploit the weaker polarity of 4-bromonitrobenzene. 4-Bromonitrobenzene has a weaker polarity due to its nitro group being in a para position thus lessening the electronegative effects of bromine on the other side of the ring by pulling electron density toward the ring1.

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.
