Preparation Of Triphenylmethanol Objectives 1. To study the preparation of triphenylmethanol using through Gridnard reaction 2. To study the operations of anhydrous reaction‚ water vapor distillation. Principles Alcohol is widely used in organic chemistry‚ not only as solute but also as intermediate to synthesize halide‚ alkene‚ ether‚ aldehyde and ketone etc. In laboratory‚ an important method of synthesizing alcohol is though the addition reaction of Gridnard reagent and carbonyl compound‚ whereas

Lab #24- Preparation 4-Methylcyclohexene Introduction: 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. Many techniques and skills were developed in this lab. Among them were dehydration‚ isolation‚ drying

Preparing Isopentyl Acetate by the Fischer Esterification Preparing Isopentyl Acetate by the Fischer Esterification Leah Monroe May 8‚ 2003 Organic Chemistry Lab II Experiment performed on April 29 and May 1‚ 2003 Abstract: The purpose of this experiment was to synthesize isopentyl acetate via an esterification reaction between acetic acid and isopentyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water

organic compounds that consist of only C and H atoms. They include the alkanes‚ alkenes‚ alkynes‚ and aromatic hydrocarbons. Because of their relatively non-polarity‚ all hydrocarbons are insoluble in water. When hydrocarbons burn in sufficient oxygen‚ carbon dioxide and water are the sole products. The main structural difference among hydrocarbon families is the presence of double or triple bonds between carbon atoms. The alkanes are saturated organic compounds‚ or those with only single bonds. Unsaturated

Cyclohexene Synthesis by Dehydration Reaction of Cyclohexanol Gjulia Vokrri 02-15-2013 Abstract Alkenes can be produced by heating and dehydrating an alcohol in the presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was

representing an aromatic ring (Webbook.nist). Table 2 also exemplifies a peak was present at 2943 and 2970 cm^(-1). Alkanes have a literature range ranging from 3000-2800 cm^(-1)‚ therefore‚ these two peaks are representing alkanes present in the molecule. The literature IR spectrum of N‚N-diethyl-m-toluamide has two peaks at approximately 2970 and 2950 cm^(-1)‚ representing alkanes (Webbook.nist).

The percent yield of the isopentyl acetate was 74.3% and this low percent yield could have occurred due to some amount of gas escaping from reflux apparatus’ top or apparatus was not fully closed so that some of the heat escaped and did not proceed the reaction well‚ leaving reagents. Another source of error could be that some of the organic layer could have been transferred along with the aqueous layer when the aqueous layer was getting separated from the organic layer by a pipette.

5. POTASSIUM PERMANGANATE Potassium permanganate (KMnO4) is used primarily to control taste and odors‚ remove color‚ control biological growth in treatment plants‚ and remove iron and manganese. In a secondary role‚ potassium permanganate may be useful in controlling the formation of THMs and other DBPs by oxidizing precursors and reducing the demand for other disinfectants (Hazen and Sawyer‚ 1992). The mechanism of reduced DBPs may be as simple as moving the point of chlorine application further
