EXTRACTION OF A KNOWN MIXTURE Separation of mixture of Acetyl salicylic acid (aspirin) and naphthalene Experiment # 6 Introduction A technique called extraction will be demonstrated in this experiment. Extraction relies on the solubility of substances into solvents and the insolubility of the solvents into each other. In this experiment, three organic compounds (aspirin and naphthalene) will be separated from each other. The two compounds are all soluble in ethyl ether (an organic solvent). By…

In Period 11 of lab, two experiments were conducted: one investigative and one preparative. Both experiments demonstrated the theory and concepts behind electrophilic aromatic substitution. As the term states, the experiments deal with the chemistry of six membered ring compounds and their transformations through electrophilic substitutions. This type of reaction transforms the aromatic compound by allowing various functional groups to be attached to it. The general process of this reaction is…

Purpose The purpose of this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in…

The MTBE operation consists of various units; the focal units are De Iso Butanizer (DIB), Butamer, Oleflex and Ethermax. Methanol produced from QAFAC, mixed butane from QP NGL facilities and water with power from KAHRAMAA and small amounts of chemicals to be used such as: 10% Caustic, DMDS, PERC and Chlorine are the required raw materials needed to generate MTBE. Producing MTBE starts with passing the Butane mixture that is in the storage sphere at QAFAC through the DIB unit where the…

The purpose of the experiment was to form ketones by electrophilic aromatic substitution through a Friedel-Crafts acylation reaction of an aromatic compound. In the synthesized Friedel-Craft acylation reaction mechanism, the double bond on the nucleophile anisole (methoxybenzene) attacks the acetyl electrophile. The acetyl compound is then bound to the anisole in the para position, which created the product p-methoxyacetophenone. Since anisole is an activator (electron donor), the acetyl could…

2. The gas phase catalytic oxidation of benzene reactor model and evaluation of the parametric sensitivity To illustrate the parametric sensitivity analysis, the case of gaseous phase catalytic oxidation of benzene to maleic anhydride was considered (Lupușor et al., 1981). The multi-tubular reactor (heat exchanger type) with the fixed bed catalyst inside a small diameter tubes (under 3 -4 cm) is continously cooled by molten salt mixture (nitrates and nitrites mixture; Maria , 2007). The raw…

in our environment. Benzene is one of them, it evaporates rapidly, it smells sweet, flammable, colorless liquid, it presents in gasoline, crude oil, and cigarette smoke. Benzene is one of the chemical contaminant which used in manufacturing many products like plastics, synthetic fibers and resin. Also, it is used to solve waxes, oils, resins, and rubber. We can get exposure to benzene from tobacco smoke, motor vehicle exhaust, gas station, glues, paints, and detergents. Benzene has many…

chemical contaminant in the substance that we are using every day. There is property or characteristic for some contaminants which is volatile, this lead to having like these contaminates in our environment. Examples of these substances include: benzene, pesticides, deodorants, and disinfectants. Chemical carcinogen are odorless, colorless, naturally or man-made substances responsible to cause harmful effects on the environment and the human. For example, these substances are considered…

b) A mixture of 50 mol % benzene and 50 mol % toluene is distilled under exactly the same conditions as in Part a. Using Figure 4.3, determine the distillation temperature and the percentage composition of the first few drops of distillate. The distillation temperature is 93 °C. The percentage composition is 75 mole percent of benzene and 25 mole percent of…

angles. Ethics will be at the forefront of this case with the how to go about getting justice for Mrs. Spirelli and her child as they were at the wrong place at the wrong time. There isn’t much doubt that if the State/Mr. Spirelli would sue Dr. Benzene and/or Mr. Johnson they would win. So the question really is who should they sue? The Doctor could be sentenced at a max to five years in prison plus assigned damages and at a minimum, probation. On the other hand Mr. Johnson could serve…
