Teradyne Corporation The Jaguar Project Case Summary

1,2,3,4-tetraphenylnaphthalene is prepared by first producing benzyne via the unstable diazonium salt. Then tetraphenylcyclopentadienone and benzyne undergo a diels-alder reaction to create 1,2,3,4-tetraphenylnaphthalene.

The main goal of this lab experiment is to synthesize acetylsalicylic acid through using different processes such as crystallization and filtration. Additionally, determining the purity of the synthesize product alongside with a commercial ASA provided in the lab, through using one of the melting point apparatus or conducting a USP test are also the objectives of this experiment.

In this experiment, the reaction kinetics of the hydrolysis of t-butyl chloride, (CH3)3CCl, was studied. The experiment was to determine the rate constant of the reaction, as well as the effects of solvent composition on the rate of reaction. A 50/50 V/V isopropanol/water solvent mixture was prepared and 1cm3 of (CH3)3CCl was added. At specific instances, aliquots of the reaction mixture were withdrawn and quenched with acetone. In addition, phenolphthalein was added as an indicator. The aliquots were titrated against sodium hydroxide (NaOH) solution until end point was reached, after which volume of NaOH consumed was recorded. The value of the rate constant, k, obtained was 0.0002 s-1. The experiment was then repeated with 40/60 V/V isopropanol/water mixture and a larger value of k = 0.0007 s-1 was obtained. We concluded that the rate of hydrolysis of (CH3)3CCl is directly proportional to water content in the solvent mixture.

Due to water’s polar structure, ions in some compounds attract and form bonds with water molecules, forming hydrates. A hydrate is a salt that has water molecules trapped within its crystals. Every hydrate has a certain number of water molecules weakly bonded to the salt as follows:

The objective of this experiment was to use an aldol condensation reaction to synthesize 3-nitrochalcone from 3- nitrobenzaldehyde. This was accomplished with a Diels-Alder reaction that utilized 3-nitrobenzaldehyde, acetophenone, ethanol, and sodium hydroxide.

Unlike other manufacturing industries, aircraft manufacturing is considerably large and complicated. It is a field with high risk involvement. Losses incurred can be quite huge due to the size of the industry. Being the case, the aircraft manufacturing industry calls for intrinsic planning and comparatively larger pool of skilled and cooperative manpower for successful production. The Boeing 767 case study focusses on the manufacturing of Boeing 767, which contains 3.1 million pieces and 85 miles of wiring. The case study lays out the project management approach of Boeing in detail. Some of the factors critical to project success are project mission, top management support, schedule and plans,

In cycle one, the double displacement reaction, Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) occurred, the result of the reaction was that the reaction mixture began to bubble with the copper filling dissolving and a vapor like substance leaving the reaction. Furthermore, when water was added, the color change, from brown to a blue color pigment. Then in Cycle two, another double displacement reaction occurred, Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq), which resulted in the reaction becoming cloudy and a darker shade of blue. Following cycle two, a decomposition reaction occurred as the result of heat being administered to the mixture, thus the following reaction occurred in cycle three, Cu(OH)2(s) → CuO(s) + H2O(l). As a

A hydrate is a compound, where water molecules are chemically bounded to another compound or element. An anhydrate is the substance remaining after removing water from a hydrate. The hydrate in this lab was Copper Sulfate. The hydrates formula is CuSO4 times xH2O. The purpose of this lab was to pull the water from a hydrate to expose the anhydrate and calculate what the hydrate is by finding the formula for the

On or about Tuesday, September 1, 2015 at 1941 hours your AFFIANT received a phone call from an off duty Shenandoah police officer William MOYER. MOYER stated he is on the 100 block of N. Market St. where a fight in progress is going on. MOYER stated the actors are Jennifer ADAMS and Stephen MACKERAVAGE.

Candidate Okane has a clear understanding of the five paragraph order and was confident and poised when briefing her fire team. SNC successfully covered most of the subparagraphs of the order but failed to brief an initial scheme of maneuver. During the execution, she quickly began to take action; however, she failed to think ahead and match the materials available with the different parts of the problem. Her failure to identify where to properly employ the equipment led her to spend a significant amount of time trying to get over the first part of the obstacle, eventually causing her to change her initial plan. Changing her plan demonstrated that she had the ability to identify and address friction areas. Throughout the execution, Candidate

SPC Hendricks’s ability to understand and retain information during a weeklong Call for Fire training set him apart from his peers. After receiving his training, SPC Hendricks called more fire missions than any other snipers or scouts and neutralized the most targets in the entire platoon. SPC Hendricks proven himself to be a subject matter expert by outperforming both infantryman and cavalry

Chevron Phillips Chemical Company is the major producer of Cyclohexane. This successful company hoses the three largest cyclohexane plants in the world. Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered. There are two methods of obtaining cyclohexane. These two methods are fractional distillation of naphtha and hydrogenation of benzene. Research suggest that the hydrogenation of benzene is the most economical way to create our chemical of choice. According to ICIS, cyclohexane is used in the production of adipic acid used to
