Synthesis of Adipic Acid

In the 1 equivalence trial, the product was never elected due to the round bottom flask being dropped at the end of the reflux stage. The 1 trial was a little more successful but not enough product was collected to analyze. The 1:5 trial seemed more successful until the rationalizations was performed and the product would not recitalist due to the high PH. After crashing with 1. MM HCI (?ml) to drop the pH and letting set for 48 hours, a lengthy vacuum filtration (product was very viscous) a white crystal formed and dried and a melting point analysis was performed.

The m. P. Showed the product to be very impure and he product starting melting at ICC and by ICC the white crystal was not finished melting yet. Trial 1- In experiment 1 (experiment 2 in notebook) the procedure was changed to give a solution to the problem of not receiving product in all three equivalences. The solution the group came too was to heat the reaction in a water bath to help facilitate better control of the temperature that the reaction is proceeding at, as opposed to using a round bottom flask on a round bottom heating element.

The new method of heating the reaction vessel seemed to have a significant effect on the yield. The mount of Cyclones used was changed to 1. 0 g due to a limited amount being available. The 1:3 trial showed no significant yield, this being expected because the minimum equivalence to obtain results is 1:4. In the trial for 1:4 a yield of 0. 361 g (0. 0025 mol) at 20. 3% yield seemed like a successful experiment. Upon analysis a m. P. Of 146-ICC showed a bit of impure product, the purity could have been effected by GA, AS, or CHAD.

More trials would need to be performed at different equivalence ratios to properly discern a clear optimal equivalence for production of DAD. It is unclear whether it was the temperature, equivalence or time reacted that resulted in the production of such impure samples, and would need to be explored more in the future with many more data sets. In conclusion, when the equivalence of Hydrogen Peroxide is varied in the green synthesis of Dipodic acid via oxidation of cyclones, there will be an increase in product yield from 1:3 to 1:4 due to the molar ratio of H2O ?+ SOCIO and complete oxidation of the cyclones ring.

When the equivalence increases to 1 a decrease in product yield occurs and could be caused by over-oxidation of the cyclones and impurities would ensue. This shows that there may be an optimal equivalence in the 1:4. 1 to 1:4. 9 range which is supported by (Penn Jinn, 2010) at al, and could have wide ranging implications in the medical field or production of synthetic polymers. In the production of any synthetic material yield is extremely important to a business owner; in which the higher the yield, the lower the cost to the consumer.
