Ethylene Glycol was first discovered in 1859 by a French chemist named Charles Adolphe Wurtz. Ethylene Glycol original purposes were to use them as raw material that manufactured polyester fibers and for antifreeze formulations. It's mainly used for industrial coolants for gas compressors, heating, ventilating, air conditioning systems, and ice skating rinks. Ethylene Glycol is an organic compound belonging to the diols family. The chemical properties are its melting point which is 8.78F, boiling point 387.1F, state at room temperature -12.9C, and its density 1.11g/cm3. The common name is Ethylene Glycol but also know has ethanediol, 1,2-Hydroxyethanal, and Monoethylene Glycol.
Some of the uses for Ethylene Glycol is that it helps your car
engine from freezing in the winter and used as a coolant to reduce overheating in the summer. Also is used for antifreeze, in hydraulic fluids, and in the manufacture of low-freezing dynamites. Then the applications for Ethylene Glycol is that it’s commonly used in many commercial and industrial applications. It is the most important glycol commercially available and is manufactured on a large scale in the United States. It was first synthesized in 1856 by French chemist Charles Adolphe Wurtz. During WW1 Germans used Ethylene Glycol in explosives. Ethylene Glycol can give you many symptoms when exposed to, such as vomiting, drowsiness, coma, metabolic changes, and many others. In the air, Ethylene Glycol reacts to photo-chemically produced hydroxyl radicals with a resulting atmosphere half- life of two days. Ethylene Glycol isn't persistent in air, surface water, soil, is practically non toxic to aquatic invertebrates. Ethylene Glycol has many uses in antifreeze, cooling, heating systems, and hydraulic brake fluids. Ethylene Glycol by ingesting large amounts of the chemical it can affect the human body by depression, nervous system, and renal damage. Various studies show that rodents that are exposed orally or by inhalation showed Ethylene Glycol to be fetotoxic
The goal of this two week lab was to examine the stereochemistry of the oxidation-reduction interconversion of 4-tert-butylcyclohexanol and 4-tert-butylcyclohexanone. The purpose of first week was to explore the oxidation of an alcohol to a ketone and see how the reduction of the ketone will affect the stereoselectivity. The purpose of first week is to oxidize the alcohol, 4-tert-butylcyclohexanol, to ketone just so that it can be reduced back into the alcohol to see how OH will react. The purpose of second week was to reduce 4-tert-butylcyclohexanol from first week and determine the effect of the product's diastereoselectivity by performing reduction procedures using sodium borohydride The chemicals for this lab are sodium hypochlorite, 4-tert-butylcyclohexanone
Alcohol, which is the nucleophile, attacks the acid, H2SO4, which is the catalyst, forming oxonium. However, the oxonium leaves due to the positive charge on oxygen, which makes it unstable. A stable secondary carbocation is formed. The electrons from the conjugate base attack the proton, henceforth, forming an alkene. Through this attack, the regeneration of the catalyst is formed with the product, 4-methylcyclohexene, before it oxidizes with KMnO4. In simpler terms, protonation of oxygen and the elimination of H+ with formation of alkene occurs.
What makes a T.V. commercial memorable? Is it the product you remember or just the commercial itself? Many times it could be both, depending on the person that’s watching the commercial. Sitting down to watch the television is more than just enjoying your favorite TV show; it’s about seeing the different types of commercial that comes with it. Commercials will play a huge role in today’s society.
A weak peak was at a position between 1600-1620 cm-1 can also be seem in the IR, which was likely to be aromatic C=C functional group that was from two benzene rings attached to alkynes. On the other hand, the IR spectrum of the experimental diphenylacetylene resulted in 4 peaks. The first peak was strong and broad at the position of 3359.26 cm-1, which was most likely to be OH bond. The OH bond appeared in the spectrum because of the residue left from ethanol that was used to clean the product at the end of recrystallization process. It might also be from the water that was trapped in the crystal since the solution was put in ice bath during the recrystallization process. The second peak was weak, but sharp. It was at the position of 3062.93 cm-1, which indicated that C-H (sp2) was presence in the compound. The group was likely from the C-H bonds in the benzene ring attached to the alkyne. The remaining peaks were weak and at positions of 1637.48 and 1599.15 cm-1, respectively. This showed that the compound had aromatic C=C function groups, which was from the benzene rings. Overall, by looking at the functional groups presented in the compound, one can assume that the compound consisted of diphenylacetelene and ethanol or
The boiling point of the product was conducted with the silicone oil. Lastly, for each chemical test, three test tubes were prepared with 2-methylcyclohexanol, the product, and 1-decene in each test tube, and a drop of the reagent were added to test tubes. The percent yield was calculated to be 74.8% with 12.6g of the product obtained. This result showed that most of 2-methylcyclohexanol was successfully dehydrated and produced the product. The loss of the product could be due to the incomplete reaction or distillation and through washing and extraction of the product. The boiling point range resulted as 112oC to 118oC. This boiling point range revealed that it is acceptable because the literature boiling point range included possible products, which are 1-methylcyclohexene, 3-methylcyclohexene, and methylenecyclohexane, are 110 to 111oC, 104oC, and 102 to 103 oC. For the results of IR spectroscopy, 2-methylcyclocahnol showed peaks at 3300 cm-1 and 2930 cm-1, which indicated the presence of alcohol and alkane functional group. Then, the peak from the product showed the same peak at 2930 cm-1 but the absence of the other peak, which indicated the absence of the alcohol
An emulsifier is some sort of ingredient that helps the stabilization of an emulsion. The emulsifier coats the oil droplets and allows mixing, shaking, etc. It also stops the clumps between the oil and water. The most common emulsifiers are proteins, gums, and fatty acids. Some of the most commonly known emulsifiers are egg yolk, dry mustard, and cornstarch. Several foods contain emulsifiers like cakes, breads, margarine, mayonnaise, peanut butter, caramels, milk, and ice cream. Emulsifiers also help the food by helping it stay fresh and preserving good quality. In spreads like butters or margarines, it helps prevent mold.
Before using ethylene to produce polyethylene, the compound needs to be purified to almost 100%. In order to reach this level of purity the ethylene needs to be freed of olefins, acetylenes, dienes and water through several processes such as: driers are used to take out the water, a demethanizer is used to remove methane, etc. ...
Normally, emulsified water is generally present in crude oil as a result of the mixing occurring during production operations and referred to as oil field emulsion. This emulsion can be encountered at numerous stages include during drilling, producing, transporting and processing of crude oil. However, the formation of emulsion creates problems in oil field industry. They might increase the cost of production and also transportation; accumulate in the refinery tank age, pipeline corrosion, equipment failure, plugged pipeline. For economic and operational reasons, it is necessary to remove water completely from the crude oil emulsion before refining and transporting those. In order to separate the water content of the produced crude oils, the emulsions have to be broken through demulsification process.

Methanol and Ethanol have differences as Methanol melts at a higher temperature and boils at a lower temperature than Ethanol. Higher alcohols, which include Butanol and Propanol, have a higher molecular weight and this is why Butanol is used in perfumes. Ethanol, which is sugar based, with its low freezing point, has a specific use as an antifreeze for cars and other vehicles. GRAPH Tripod Matches Goggles Method: To begin with, I choose one of the four different alcohols. I weigh beforehand in the spirit burner.
