The separatory funnel was shaken three, times, and off-gased after each time.
Isoborneol is one of its corresponding secondary alcohols such that this carbon atom has a bond with hydrogen and a bond with the hydroxide ion (H-C-OH).
A top face, nucleophilic attack results in the product borneol and a bottom face nucleophilic stack, The first part of the experiment was the oxidation of isoborneol. it.
The sodum chloride acts as a catalyst to the process described….CONTINUED, IMPORTANT!!! If isoborneol is oxidized to camphor, and then camphor is reduced, it will form two, products (isoborneol and borneol) due to the fact that there are two possibilities for a, : Figure one shows the mechanism for the oxidation of isoborneol to form, : Figure two shows the mechanism for the reduction of camphor.

Lastly, the beaker was placed in a, warm bath at 37.5°C to allow the ether to evaporate. Reduction was achieved by reducing camphor to isoborneol and borneol.
Week 1 Reading The background reading for this experiment is in Pavia (5th edition), Experiment 31, Parts A, B and C, and Technique 17 (Sublimation). 1 Camphor is a model compound in its ability to produce isomeric secondary alcohols, such as isoborneol and borneol, when it is reduced.
This reaction is shown in figure 2. Then, the bleach was added and the mixture was swirled. The reaction scheme is illustrated by the drawing shown below; As per the lab manual, the green oxidizing agent utilized in this experiment has the capability to oxidize the chloride ion from the sodium chloride into molecular. Then, 10 mL of, sodium bicarbonate was added to the funnel, the funnel was shaken, and the aqueous, layer was removed. The test strip, turned blue, indicating that the layer was basic.
Paulerni G. Date Performed: 1/27/16, 2/3/16 CH 26AA Date Submitted: 2/10/16 EXPTS.
1 AND 2: REDUCTION OF CAMPHOR TO ISOBORNEOL and OXIDATION OF ISOBORNEOL TO CAMPHOR DATA AND RESULTS Table 1.1. in figure 1.
If you are author or own the copyright of this book, please report to us by using this DMCA Let camphor be called C. Let isoborneol be called B. Next, anhydrous sodium sulfate was, added to the organic layer to remove any water present.

Next, 15 mL of diethyl ether was added to the separatory, funnel, along with 1 mL of sodium bisulfate. This preview shows page 1 - 4 out of 8 pages. For a limited time, find answers and explanations to over 1.2 million textbook exercises for FREE! The properties of camphor
The purpose of this lab report is to demonstrate the green approach of oxidizing (1S)-borneol to (1S)-camphor. So the theoretical yield is 0.5g also.
1. report form. Camphor was reduced by using the reducing agent sodium borohydride. Camphor and Isoborneol differ only by the bonds of a single carbon atom. Then, the aqueous layer was removed from the, funnel and 10 mL of sodium bisulfate was added to the organic layer.
It is one of the active ingredients in Vicks VapoRub and is used to reduce pain and inflammation.
Report DMCA, COLOYAN. Camphor and its reduction products, borneol and isoborneol, come from a bicyclic family called terpenes. It replaces them with environmentally friendly Oxone and benign triple salt. The oprocedure for Part A given below is based on a modified procedure from Dr. Donald Watson at the University of Delaware Prelab strip, which was negative. Then, the solution was tested with a starch iodine test. Oxidation of Isoborneol to Camphor Procedure: Measure out 2.5 grams of isoborneol and fully dissolve it in 6 mL of glacial acetic acid in a 125 mL Erlenmeyer flask. The purpose of this lab report is to demonstrate the green approach of oxidizing (1S)-borneol to (1S)-camphor. The green approach of camphor synthesis is beneficial since it replaces the use of traditional oxidizing agents such as the chromium reagent and organic peracids. A new green oxidation procedure was developed for the undergraduate organic teaching laboratories using Oxone and a catalytic quantity of sodium chloride for the conversion of borneol to camphor. Add 25 mL of chlorox bleach , slowly, dropwise over five to ten minutes maintaining the temperature between 5-15 degrees celcius using a cold bath. 0.5gC x 1molC/152.23 x 1molB/1molC x 154.25gB/1molB = 0.507g isoborneol (theoretical yield) Because the weight of camphor is given as 0.5g, you are only allowed one significant figure. During such process, the oxidation was carried out in small scale to enable the extraction of the product and the subsequent desiccation and sublimation. Introducing Textbook Solutions. Then, 15 mL of water was added to the mixture and the mixture was transferred to a, separatory funnel apparatus. Such a process has numerous applications within the medical and pharmaceutical world.
achieved by oxidizing isoborneol to camphor. Oxidation is the increase of carbon-oxygen, bonds, or a decrease of carbon-hydrogen bonds.
