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

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 Paper By: Shineka Bell July 11‚ 2010 Water is an essential part of our every day lives‚ whether we know it or not. In the body water bathes the cells of the body and lubricates and cleanses internal and external body organs. Watery tears lubricate the eyes and wash away dirt‚ saliva lubricates the mouth‚ making it easier to chew and swallow foods. Water resists compression so it cushions body compartments such as the joints and eyeballs against shock. In addition‚ water functions

Dehydration of 2-Methylcyclohexanol February 10‚ 2013 Introduction This experiment was done to demonstrate the practical use of dehydration reactions and produce three different products. Dehydration reactions are reactions that involve the leaving of an “-OH” or “-H” group resulting in the formation of a double bond between two carbons. For the experiment we used 2-Methylcyclohexanol as a beginning reagent to dehydrate and possibly form 3-methylcyclohexene‚ 1-methylcyclohexene‚ or methylenecyclohexane

vaporisation and secondly mass transfer is taken place as the water goes away from the food stuff (Earle‚ 1983). The Rate of drying depends on the type of food‚ the processing conditions and the design of the drier (Fellows‚ 2000). The practical of dehydration of tomatoes was carried out in a cabinet dryer that was operated at the temperature of 80°C. In the cabinet dryer the food material was spread out on the trays and heating was facilitated by an air current sweeping across the trays (Earle‚ 1983)

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is

Dehydration and hyperthermia Dehydration is a deficit of total body water‚ with an accompanying disruption of metabolic processes. dehydration can also cause hyperthermia. Dehydration occurs when water intake is insufficient to replace free water lost due to normal physiologic processes and other causes. Hypovolemia is a related condition specifically meaning a decrease in volume of blood plasma‚ not of total body water. Bothe are regulated through independent mechanisms in humans and should not

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 Paper Water is one of the most important things we need in order to live. Water is everywhere; you can find it at any store or home. If it’s not free then it’s cheap to buy. In this paper we will discuss how water affects your body and many other issues relating to water and ourselves. Your body is made of about 70% of water. That is a big percentage of your bodies’ makeup. If you don’t drink water for a few days you will die. This fact alone should tell you how important it

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
