Copper-Catalyzed Oxidation of Benzoin to Benzil prepared by Carl T. Wigal, Lebanon Valley College PURPOSE OF THE EXPERIMENT Oxidize benzoin to benzil using ammonium nitrate and copper(II) ion as a catalyst, monitoring the reaction by thin-layer chromatography. Characterize the product using melting point measurement and infrared spectroscopy.

PBX simulated wastewater before and after the ozone oxidation was extracted thrice with dichloromethane. The obtained dichloromethane extract was dried over anhydrous sodium sulfate and then analyzed using an Agilent Technologies 7890A-5975C Gas Chromatography-Mass Spectrometry (GC/MS) (Agilent Technologies, America) for the final product analysis of gas phase system. Approximately 1.5 mL sample was heated from room temperature to 330 °C and kept at this temperature for 15 s. The chromatographic

3.1 REPSA I Inspection Findings On July 7, 2015 the EPA and MARN inspected the REPSA I facility, including the oxidation lagoon treatment system. This wastewater treatment system treats the wastewater generated from REPSA I palm tree oil processing. The system consists of five oxidation lagoons, which included cooling stabilization lagoons, anaerobic (an anaerobic lagoon is a deep impoundment, essentially free of dissolved oxygen that promotes anaerobic conditions (USEPA 2002)), and facultative

Extended Essay in Group 4 – Experimental Sciences: Chemistry An Investigation on the Temperature and Environment in Which Commercial Orange Juice is Stored and its Effect on Ascorbic Acid Content with the Influence of Time XXXXXXX XXXXXX Candidate Number: 000166-XXX Seoul Foreign School, South Korea Word Count: 3772 May 2013 Exam Session 000166-XXX 1 Abstract   Ascorbic acid, commonly known as vitamin C, is considered one of the most essential vitamins for our bodies. With the popular belief

Through an oxidation-reduction reaction sequence, Borneol is converted to isoborneol. First, borneol is oxidized through a reaction with sodium hypochlorite at 400C to form camphor. When the camphor is then reduced by sodium borohydride, isoborneol is formed. The percent yeild of isoborneol collected was 56.4%, and the melting point range was found to be between 174.2-179.90C. Through analysis of the product through 1H NMR spectroscopy the percent purity is found to be 77.2% pure isoborneol.

Matthew Potzler CHEE 569B Term Project Zeolite-Based Sorbent Coated with Iron for Advanced Oxidation of Trace Organics in Treated Wastewater Abstract Zeolite with an iron loading of 0.11% was used in a set of experiments to determine the possibility of using zeolite in conjunction with Fenton’s reagents in order to destroy p-Cresol in an aqueous solution. The results were compared to a homogenous system at a pH of 2.5 using iron salt with an equivalent iron concentration of iron-amended zeolite

Introduction The purpose of this lab was to discover the effects that an alkyl group and solvent have on the rate of SN1 and SN2 reactions. Two separate mechanisms can be used to perform the nucleophilic substitution of alkyl halides: SN1 and SN2. A SN1 reaction, or unimolecular displacement, is a 1st order, nucleophilic substitution that involves two steps. The rate law for this reaction, Rate = k[Rx], doesn’t include the nucleophile in it.1 These two step reactions have a carbocation intermediate

The objective of this lab was to create a ketone through an oxidation reaction using a using a secondary alcohol and oxidizing agent in order to use that ketone in a reduction reaction with a specific reducing agent to determine the affect of that reducing agent on the diastereoselectivity of the product. In the first part of this experiment, 4-tert-butylcyclohexanol was reacted with NaOCl, an oxidizing agent, and acetic acid to form 4-tert-butylcyclohexanone. In the second part of this experiment

1.4 Methodology 1.4.1 Process definition Advance Oxidation Process is a set of chemical treatment where the organic waste and some inorganic waste are removed from industrial wastewater, pharmaceutical wastewater by oxidation through reactions with hydroxyl radicals (·OH). In real world it is applicable for the removal or treatment of wastewater. This reactive spices are strongest oxidants which can be used to virtually oxidize any compound which is present in the water matrix and also can be
