Methyl ethyl ketone is one of the top 100 chemicals produced worldwide due to its high demand and versatile end use. This paper will analyze and compare the production processes of methyl ethyl ketone using patent protected methods of two of the industry’s chemical production leaders, Maruzen Petrochemical Co. and ExxonMobil Corp. The analysis of the two methyl ethyl ketone production methods will enable us to bring to light the evolution of the production process over time and the impact which these processes have on energy consumption and waste production. By comparing the patent protected method for producing methyl ethyl ketone of world’s leading producer of methyl ethyl ketone, Maruzen Petrochemical Co., with ExxonMobil Corp.’s patented method, and the conventional method we will be able to determine the more favorable process based on their impact on the environment, turnover time, and energy consumption. There are many industries that have use for methyl ethyl ketone, specifically the automotive, electrical goods, and furniture industries. The main application of methyl ethyl ketone is in the paint and coatings industry which contributed to half the global demand. Methyl ethyl ketone exists in many consumer products available worldwide. A couple of consumer products containing methyl ethyl ketone will be selected and have their chemical composition broken down and analyzed to see what role methyl ethyl ketone plays in the composition of the products. Methyl ethyl ketone production by Maruzen Petrochemical Co. Maruzen Petrochemical Co., located in Tokyo, Japan, is the world leader in methyl ethyl ketone production. The Maruzen Petrochemical Co. patented process for producing methyl ethyl ketone is rather quite simple w... ... middle of paper ... ..., whereas in Europe and North America not much need or growth of methyl ethyl ketone is seen.1 The growth is expected to rise at an average rate of 1.9% in a span of 4 years from 2010-2014, with most of the growth coming within the Asian market.1 As we progress towards the future, it is evident that methyl ethyl ketone will continue to act as a key player in the chemical industry. New processes are being developed to produce methyl ethyl ketone in a much safer and faster manner, with less energy consumption and less environmental impact, as was exemplified by Maruzen Petrochemical Co.’s patented process. As more and more applications and uses of methyl ethyl ketone are discovered, the demand for the chemical compound will increase and thus inspire chemical manufacturing companies to research and develop new methods and tools in producing methyl ethyl ketone.
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
The goal of this lab is to exemplify a standard method for making alkyne groups in two main steps: adding bromine to alkene groups, and followed by heating the product with a strong base to eliminate H and Br from C. Then, in order to purify the product obtained, recrystallization method is used with ethanol and water. Lastly, the melting point and IR spectrum are used to determine the purity of diphenylacetylene.

The failure occurred during production and resulted in the death of 4 and injuries to 32 people, 28 of which were members of the community. (CSB, 2009)
Chemical Vapor Deposition is the most popular method for producing CNTs the process involved high temperature, hydrocarbon source such as methane which is decomposed in the presence of a metal catalyst (Ando, 2004). There are various types of Chemical Vapor deposition processes, but this method is recognized as Catalytic Chemical Vapor Deposition which is comparatively less expensive to Laser Ablation and Arc discharge methods (Ando, 2004). Chemical Vapor deposition is a flexible and lean way to produce Carbon Nano-tubes. It is very versatile process in which source hydrocarbon can be supplied in any form (Solid, Liquid or gas) and we can use substrates such as Ceramic bricks, cement, glass wool etc. The growth of C...
According to §2 para. 6 No. 2 of the German food law, cosmetic packaging materials are viewed as items for everyday and common use. The Regulation 1223/2009 provides assurance to consumers that the product they use is safe for application. The reference 1935/2004 was suggested to portray close formulation/packaging combinations that are already present in the market. Therefore, with this, food/packaging interaction may be contemplated. Since materials manufactured for the packaging of food products have already undergone several tests, suitable information regarding the stability of that material may already be accessible. Hence further experimental procedures may not be necessary. The 1935/2004 regulation is not normally used for cosmetic packaging. However, without the presence of any other established guidelines, this regulation is used to check the congruity of the packaging. For instance the packaging material of cosmetic products are compared with and judged against the packaging of food items. Verification in the shipping document is done by the food control agency or the supplier company to show that the packaging material

The most common form of polyethylene is petroleum based or olefins based; as before mentioned polyethylene compounds have a wide commercial applicability and are made from non-renewable resources (Harding, Dennis, von Blottnitz, Harrison, & S.T.L., 2007). Its manufacturing processes are regarded as energy intensive and release significant amount of CO2 and heat into the atmosphere (Broderick, 2008). Next a little more detailed description of polyethylene’s production processes will be presented, with a focus on the way the material inputs are extracted and synthesized.
Fossil fuels such as coal, petroleum, and natural gas are currently the world’s largest energy supply sources. However, all of it is non-renewable resources which means that it will take extremely long time to be formed and with the huge amount of consumption rate, one day the world will ran out of its main energy source. Therefore, alternative energy sources are needed to cut off the dependence on fossil fuels. One of the best alternative energy sources is ethanol. Ethanol is a renewable energy source as it uses sunlight, which will last almost forever, as a part of its production process. Ethanol is also an environmental-friendly energy source because it helps in reducing smog pollution and carbon dioxide emissions by up to 50%. This makes ethanol a perfect alternative energy source. Ethanol can act as a raw material for polymers such as polyethylene through the dehydration reaction. This dehydration reaction has been known and popular for many decades because of its simplicity, the reaction process is also claimed to be not cost-competitive, which is why ethanol can be used as a raw material for polymers.
In a small reaction tube, the tetraphenylcyclopentadienone (0.110 g, 0.28 mmol) was added into the dimethyl acetylene dicarboxylate (0.1 mL) and nitrobenzene (1 mL) along with a boiling stick. The color of the mixed solution was purple. The solution was then heated to reflux until it turned into a tan color. After the color change has occurred, ethanol (3 mL) was stirred into the small reaction tube. After that, the small reaction tube was placed in an ice bath until the solid was formed at the bottom of the tube. Then, the solution with the precipitate was filtered through vacuum filtration and washed with ethanol. The precipitate then was dried and weighed. The final product was dimethyl tertraphenylpthalate (0.086 g, 0.172mmol, 61.42%).

The process need toluene and hydrogen as a main reactor. Then, toluene and hydrogen are converted in a reactor packed with catalyst to produce benzene and methane. This reaction is exothermic and the operating conditions are 500 0C to 660 0C, and 20 to 60 bar of pressure. This process begins with mixing fresh toluene with a stream of recycle unreacted toluene, and the mixing is achieved in a storage tank. Then, the toluene is pumped to combine it with a stream of mixed hydrogen and fresh hydrogen gas. The mixture of toluene and hydrogen is preheated before it is introduce to the heater or furnace. In the furnace, the stream is heated to 600 0C, then introduced into the reactor. Basically, the main reactions occurs in the reactor.
Ethylene glycol is widely used in many sectors such as production of polyester fibre, polyester resins and others. Due to the various usage of ethylene glycol, the high and increasing demand of ethylene glycol is expected.
The growing relevance of Chemical Engineering in today’s world, from energy & oil industries to pharmaceuticals & biotechnology, and a keen desire for applying this knowledge in interrelated spheres motivates me to pursue a Master’s degree in this field. My interest in science goes back to the time when I was in school. We had a young and enthusiastic teacher who took us on field trips and visits to science fairs and museums. This nascent interest has only burgeoned through my years in school and high school, as I have learnt more about the subject. In the long run, I see myself as a part of a leading research group, either as a faculty member or in the R&D department of an organisation contributing my bit to the field of Chemical Engineering. As a research scientist, I hope to make a difference in this field and learn more through the innovative challenges.
