Dehydration of Cyclohexanol Introduction In this experiment cyclohexene‚ an alkene‚ was prepared by the dehydration of cyclohexanol‚ an alcohol‚ using phosphoric acid‚ an acid catalyst. The reaction is as follows: [pic] The dehydration of cyclohexanol was performed in a simple distillation apparatus. As cyclohexene formed‚ it was distilled out of the mixture. Background Dehydration is an elimination reaction of an alcohol that takes place in the presence of an acid catalyst

Bacevich states that the call for a “comprehensive strategy” concerning what to do in Iraq has been gaining support in the U.S. However‚ the plan involving air strikes and surrogates on the ground is nothing more than a “whack-a-mole” to Bacevich. He states that the main problem in the Middle East is not ISIS‚ but the social‚ political‚ and economic problems plaguing the region. The problems remain without ISIS‚ and will more than likely reoccur with another group. He says that even if we succeeded

A multicenter trial was conducted to evaluate the efficacy of Lactobacillus GG administered in the oral rehydration solution to patients with acute-onset diarrhea of all causes. Methods: Children 1 month to 3 years of age with acute-onset diarrhea were enrolled in a double-blind‚ placebo-controlled investigation. Patients were randomly allocated to group A‚ receiving oral rehydration solution plus placebo‚ or group B‚ receiving

Running Head: DEHYDRATION IN HUMAN FACTORS Dehydration in Human Factors Allan Gorge Abstract Dehydration is an insidious disorder that plays a potentially deadly role in aviation and other aviation related specialties. We’ll take a look at the body’s composition of water‚ and the physiology of water loss and intake. We’ll also cover the different classifications of dehydration and there signs and symptoms. The dangers of dehydration in the role of

industry. The dried foods have long shelf life if the post process conditions are maintained thoroughly and effectively. The principal reasons behind this are the destruction of microorganisms which cause spoilage and decay of food by their growing and multiplying and also many of the enzymes that cause for undesired changes in the food cannot function properly at low water or no water level. But during drying there are two mechanisms which take place in the food‚ firstly heat is transferred to the

Today‚ the newer Natural Draft dehydrators use a 1‚000-watt element for heating as its heat source‚ or with the electric dehydrator using nine 75-watt bulbs totaling 675-watts‚ plus an electric fan. TYPES OF FOODS TO BE DEHYDRATED Solar dehydration or oven dehydration are good methods for meats‚ vegetables and fruits. If an oven is used‚ make sure there are numerous drying trays to fit on the oven’s racks‚ an accurate oven thermometer‚ and a small fan that is electric. The oven temperature should be

Causes and 2 Unipolar and bipolar disorders are fairly common and they can have devastating effects to an individual. There has been much study and documentation on these disorders. This paper will review the causes of both unipolar and bipolar disorders. The symptoms of both of these disorders will be highlighted and discussed. Treatment options will be reviewed that are available to individuals who find that they are suffering from these disorders. Unipolar disorder is characterized by an individual

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

Be Careful What You Sign There are many cases decided by courts across the country addressing the enforceability of evergreen clauses pertaining to different business transactions. In most cases‚ particularly in the context of commercial business-to-business contracts‚ courts strictly construe these provisions where the contract language is clear and unambiguous. If the contract language is not followed and notice is not given within the required time to terminate‚ the contract extends for another
