Compilation of “Dehydration of Methylcyclohexanol” Blog entries: A common Sophomore Organic Chemistry laboratory experiment that has great potential for further research is the acid catalyzed dehydration of simple alcohols. The classic dehydration of 2-methylcyclohexanol experiment that was introduced in Journal of Chemical Education in 1967 Taber(1967)JCE:44‚p620. The rather simple procedure of distilling an alcohol with an aqueous acid has spawned several investigations that have resulted

Dehydration of Methylcyclohexanols Balie Zander Date Conducted: March 27‚ 2013 Date Submitted: April 3‚ 2013 Introduction: The purpose of this experiment was to demonstrate the application of Zaitzev’s rule‚ the Evelyn Effect and the occurrence of an E1 mechanism in an alcohol dehydration reaction. Specifically this experiment involved the dehydration of 2-methylcylcohexanol by heating this alcohol in the presence of phosphoric acid and then to based on the results of the gas chromatography

Dehydration of Methylcyclohexanols 1. Introduction The purpose of this experiment was to carry out the dehydration of 2-methylcyclohexanol or 4-methylcyclohexanol by heating the alcohol in the presence of phosphoric acid. The alcohol was a mixture of cis and trans isomers‚ so it might have exhibited an Evelyn effect. It was also looked at if the products showed the Zaitsev’s rule‚ where in an elimination reaction‚ the most stable alkene was favored‚ which was usually the most substituted one and

DEHYDRATION OF 4-METHYLCYCLOHEXANOL PURPOSE Perform an acid-catalyzed dehydration of 4-methylcyclohexanol to produce 4-methycyclohexene. TECHNIQUES • Dehydration of an alcohol • Preparation of an alkene • Distillation • Unsaturation tests THEORY An acid-catalyzed dehydration is a common way to synthesize an alkene from an alcohol. Use of a strong acid like sulfuric or phosphoric acid serves to protonate the alcohol "OH" group‚ forming an H2O molecule that is a much better leaving group

IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

Dehydration In 1994‚ thousands of starving people died in the Africa nation of Rwanda. It wasn’t lack of food that killed most of these people‚ but cholera‚ a bacterial infected that cripples the ability of intestinal mucosal cells to reabsorb water. The severe diarrhea that develops can kill in days‚ sometimes even hours. Dehydration is deadly. Dehydration is a deficiency condition that occurs when output of water exceeds intake. It is a great problem for athletes‚ military personnel‚ and certain

Dehydration is when your body has lost too many fluids. Water is one of the most important nutrients to our body; the human body is from 55 percent to about 78 percent of water. The average person loses water consistently by doing everyday activities and sweating‚ breathing and eliminating waste. Water removes toxins and waste products from the body and puts nutrients into the body. Dehydration affects many people for many different reasons. Water has a HUGE effect on people when it comes to dehydration

its proper functioning. Our bodies require that we consume at least one liter of water each day. When we lack the necessary about of fluid‚ dehydration-which is when a person loses more bodily fluid than he or she takes in‚ occurs. Dehydration can occur quickly‚ gradually over a period of time. In this paper‚ I will discuss the various effects of dehydration on the human body. I will discuss the importance of water to our health‚ compare and contrast the various functions of electrolytes‚ potassium

In 2010-11‚ fruit production stood at 74.877 million tonnes and vegetables production at 146.554 million tonnes. On the other hand 18% of fruits and vegetables from India are going to waste for want of adequate storage facilities. The amount

Dehydration Jazmen Spratling SCI/241 Derrick King 04/15/2012 Dehydration Dehydration is the loss of water and salts essential for normal body function‚ the free dictionary (2012). Dehydration occurs when the body loses more fluid then it takes in. This is very dangerous to the body. Dehydration cans results from a hot‚ dry climate; prolonged exposure to sun or high temperatures; not drinking enough or other medications that increase urination. Dehydration can upset the delicate fluid-salt
