Cyclohexanol Lab Report

On a large scale ethanol and ethanoic acid is added to get the product ethyl ethanoate and water.

In an oxidation reaction, the number of C-H bonds decreases or the number of C-O bonds increases, while in a reduction reaction, the number of C-H bonds increases or the number of C-O bonds decreases. In the oxidation step of this reaction, 4-tert-butylcyclohexanone is formed from when a C-H bond is lost while a C-O bond is gained to create a carbonyl. In the reduction step, 4-tert-butylcyclohexanol is formed when the carbonyl is converted into an alcohol when a nucleophilic hydride attacks the carbonyl. Whether the OH is in the

This way, cyclohexane is converted to adipic acid or hexanedioic acid. Since the product is soluble in hot water, the two-phase systems (organic cyclohexane and aqueous hydrogen peroxide) slowly become a single aqueous phase. In the end, only H2O2 and cyclohexene can be changed, tungstate and the phase transfer catalyst can be tapped and reused. The phase transfer catalyst used were a mixture of aliquat 336 and potassium hydrogen sulphate.

The sodium hydroxide acts to pull the hydrogen off the oxygen in the 2-methylphenol so that the oxygen has a negative charge and can attack the sodium chloroacetate. Again, using a 1:1 molar ratio, 0.34 g (2.9 mmol) of sodium chloroacetate (the good leaving group) was added to 1 ml of water and dissolved. Following dissolving all of the 2-methylphenol (to avoid the sodium hydroxide reacting concurrently with the sodium chloroacetate and 2-methylphenol) in the sodium hydroxide, the aqueous solution of sodium chloroacetate was transferred to the reaction flask. This mixture was then heated to reflux, using a medicine dropper affixed to the top of the flask as an alternative method to boil without

We used TLC analysis to identify each product obtained from the dihydroxylation reactions by spotting a TLC plate with the product of our reaction, a solution of cis-cyclohexane, trans-cyclohexane, and a 50:50 mixture of the two. We then placed the plate in a beaker with ethyl acetate saturating the atmosphere to allow the TLC plate to develop. Finally, we compared Rf values of the components of the mobile phase, after the phase was completed. 100% ethyl acetate was used instead of 100% Hexane or a mixture of Ethyl Acetate, because ethyl acetate has high polarity and can separate the components of a mixture to elution, unlike hexane, which is non-polar, and therefore unable to separate the components of the mixture. A 50:50 mixture of both would not work, because the polar and non-polar compounds would neutralize the mixture, and thereby not separate the components of the mixture.

Introduction: Reaction of a compound with water can result in a splitting, or lysis, of the compound into two parts. Organic molecules containing a group of atoms called an ester can be hydrolyzed by water to form a –COOH group (carboxylic acid) and an HO-- group (alcohol) as follows:

The former compound is very reactive and therefore less selective, while the latter is less reactive and therefore more selective. NaBH4, which is used in this experiment, reduces only ketones and aldehydes. It produces primary alcohols from aldehydes and secondary alcohols from ketones. The reagent also reacts more rapidly with carbonyl groups than with the solvent, which is the reason it is used rather than catalytic hydrogenation or metal hydrides.

Abstract: Using hypochlorous acid to convert secondary alcohol called cyclododecanol to the corresponding ketone which is cyclododecanone by oxidation.

The goals in this lab were to have a reaction occur with 4-methylcyclohexanol and an acid catalyst to form our product of 4-methylcyclohexene via an E1 reaction. This reaction is accomplished by removing the –OH group on 4-methylcyclohexanol via dehydration and to have a double bond form via a loss of a hydrogen on a β-Carbon.

1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene, and to test the regiochemistry of the reaction between benzonitrile oxide and styrene.

The purpose of this lab was to carry out a dehydration reaction of 2-methylcyclohexanol by heating it in the presence of phosphoric acid and determining which alkene product would be the major product. Methylcyclohexanols were dehydrated in an 85% phosphoric acid mixture to yield the minor and major alkene product by elimination reaction, specifically E1. The alkenes were distilled to separate the major and minor products and gas chromatography was used to analyze the results and accuracy of the experiment. The hypothesis was the major product of the reaction would be the most substituted product. This conclusion was made because of

In this experiment, NaOH was the inhibitor used to stop the enzymatic reactions. NaOH is very basic and when added to a solution, will cause a drastic increase in pH, causing denaturation of the enzyme. The amount of product formed could be calculated by placing the test tube in a spectrometer after the addition on NaOH. A spectrometer measures the absorbance of a solution, which helps compare how much of a substance is in a solution.
