causing hardships‚ increased food prices‚ and other problems. Ethanol has been blamed for the rise of food prices. Since corn is used for many different things such as food for us‚ ethanol gasoline and food for animals. Even though ethanol lowers our gas mileage corn is being used more for ethanol and making it more expensive for the people who would like to eat corn on a cob. In 2013‚ 40% of corn and other crops went to produce ethanol‚ 45% was used for feeding livestock and other animals‚ and only

tertiary alcohols are the most likely to follow the SN1 pathway. In SN1 reactions‚ the formation of a carbocation can lead to rearrangements. Also‚ elimination to form an alkene can occur. In this experiment‚ t-amyl alcohol (2-methyl-2-butanol) in the presence of concentrated HCl will undergo a substitution reaction to form t-amyl chloride. In order to confirm the presence of a halide‚ use the Beilstein test. By cleaning a piece

hand sanitizer or hand antiseptic is a supplement or alternative to hand washingwith soap and water. Various preparations are available‚ including gel‚ foam‚ and liquid solutions. The active ingredient in hand sanitizers may be isopropanol‚ ethanol‚ n-propanol‚ or povidone-iodine. Inactive ingredients in alcohol rubs typically include a thickening agentsuch as polyacrylic acid for alcohol gels‚ humectants such as glycerin for liquid rubs‚propylene glycol‚ and essential oils of plants. Alcohol based

the mass and the given percent mass of ethanol‚ we found the density of pure ethanol for each known concentration of alcohol‚ and averaged the three calculated densities to give us a density of pure ethanol (0.8391 g/mL) that we could use to calculate the concentration of the unknown solution. We used this to calculate the volume of ethanol in the unknown test tube (7.918 mL)‚ and used the calculated density of ethanol to convert volume ethanol to mass ethanol in the unknown test tube (6.644 g). Since

Introduction 2 Literature review 2 Conclusion 3 Bibliography/References 3 Price Elasticity of Demand Introduction Ethanol production in the U.S. has grown tremendously in the last decade. Production was averaging one billion gallons per year in the early 1990s‚ grew to four billion gallons in 2005‚ and in 2007 exceeded six billion gallons (Renewable Fuels Association (RFA)). If current plans for new construction and expansion come to completion‚ production capacity will exceed

Distillation of an Ethanol- water Mixture Abstract The purpose of this experiment is to understand the process of distilling a solution. Thesolution of 50/50 ethanol-water was used in the experiment. Using fractional distillationapparatus ethanol-water mixture was separated. The fractional use of copper sponge wasused in distillation process which created the heat exchange area between the vapor of ethanol and liquid water. The fractional distillation process yield 9.5 ml of ethanol incollecting flask

Mohideen 1 Darik A. Mohideen Professor Jarrod Stringer English 1301 24 June 2012 Effects of Ethanol in the Society Ethanol‚ also called ethyl alcohol is a volatile‚ flammable‚ colorless liquid. The largest single use of ethanol is as a motor fuel and fuel additive. Ethanol is considered to be better for the environment than gasoline. It is a renewable source of energy and it has been seen as a promising alternative to fossil fuel consumption. However‚ there are some negative aspects in the

| Reactions of Grignard Reagents with Carbonyls | | | Tuesday 1:30 | 2/28/2012 | | Introduction This experiment explores the reactivity pattern for the addition of Grignard reagents to three different carbonyl groups: a ketone‚ an ester‚ and a carbonate. Grignard reagents are organometallic compounds that have a carbon-metal bond‚ such as carbon-magnesium. Grignard reagents are formed from the reaction of an alkyl‚ cycloalkyl‚ or aryl halide and magnesium metal in dry ether

The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected. Controlling

A Comparative Study On The Combustibility Of Ethanol (C2H5OH) And Hydrogen Peroxide (H2O2) Mixtures As Fuel Chemistry January 31‚ 2013 Revised February 15‚ 2013 Abstract In this experiment‚ the proponents used mixtures with varied proportions of ethanol and hydrogen peroxide to know which would make a more efficient‚ clean‚ and stable combination. Compared to conventional fuels‚ ethanol contains 36% oxygen thus resulting in more complete combustion. This greatly lowers
