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
In this lab 2-methyl-butyn-2-ol is hydrated to 3-hydroxy-3-methyl-2-butanone. This process was preformed by using a strong acid which created an enol, and then the enol tautomerized. Due to this being a terminal alkyne, only one product will be formed. Techniques such as simple distillation, reflux, and gravity filtration were used to produce and separate the product from the mixture that it was in. When performing this lab using only one equivalent of alkyne produced a low percent of 1%. The low
peaks (Experiment VII). The reaction with 2-butanone produced a one and five percent trans isomer fr0m GC and NMR respectively. Water as a solvent produced 79 and 80 percent trans isomer from GC and NMR (Kimmell). Both relative percentages feel within the accepted range of similarity (5-10%). The class data showed similar trends to the experimental data of relative percent mentioned above. The trans isomer relative percent for the solvent of 2-butanone is six percent and the trans isomer relative
pKa is 9. Its half-life is two hours. Nicotine is converted to its metabolites by the P450 enzyme system and by aldehyde oxidases. Nicotine and its metabolites, such as cotinine, Nnitrosomornicotinine (NNN), and 4-(methylnitrosamino)-1-(3-pyridyl)1-butanone (NNK) are toxic to humans. As is shown in P4, many people in the United States smoke. The average mg of nicotine per cigarette has declined in the United States in the1980... ... middle of paper ... ... of Epidemiology.124.633-640(1986). 23
Esters are defined as molecules consisting of a carbonyl group which is adjacent to an ether linkage. They are polar molecules which are less polar than alcohols but more so than ethers, due to their degree of hydrogen bonding ability. Most often derived from reacting an alcohol with a carboxylic acid, esters are a unique, ubiquitous class of compounds with many useful applications in both natural and industrial processes 1. For example, within mammals, esters are used in triglycerides and other
The American people love fast food, but little do they know about what is really in their “hamburger” or “chicken nuggets”, and what damage the real ingredients in these foods can cause. Fast food has become a great part in many people’s lives today because you could get it fast and on the move and it’s also cheap. Everyone has eaten fast food at one point in their lives, unless of course they don’t eat meat, but they really don’t have a clue as to what they’re ingesting. This paper will inform
Introduction: Food dyes were originated from nature in the past and they were first used cover poor quality or spoiled food. Over the years, scientists during the 1800’s started to search for methods in which to colour food artificially, when people started to consume these coloured foods, this led to many injuries and deaths unfortunately. Nowadays, colours used in foods have to be regulated by the government before they can be used . These synthetic food dyes are added to many types of food to
