Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent, while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

binds more tightly to Cu+ than Cu2+ and that it is important to the in vivo oxidation state. Plus, they showed in an earlier study that the slowness of the Cu+ Aβ helps to slow down the production of ROS, which would slow the neurodegeneration seen in AD. Also, the amount of ascorbate that is present in extracellular fluid could generate Cu+, even though in plasma extracellular copper is thought to only be in the Cu2+ oxidation state. The authors acknowledge that this is a controversial finding and that

I’ve learned mny topics in Consumer Chemistry but one of the mot important lesson and the hardest (for me) is the Redox or Oxidation-Reduction Reaction. Why is it the hardest topic for me? Well, at first, while our teacher was discussing this, I thought that this lesson is pretty easy because I understand all her lessons and I had no problem absorbing the lessons. Butwhen the

INNOVATION OF HYDROTHERMAL SYNTHESIS FRON THE PAST & PRESENT Traditional Hydrothermal Synthesis since the end of the 19th century, hydrothermal synthesis of inorganic materials has been carried out. It is defined as the precipitation of these materials from aqueous solutions at temperatures above the boiling point and at pressures greater than ambient pressure. This method is actually environmentally because it does not require any organics or additional processing such as calcinations. That is

which has attracted notable attraction among the researchers. This field has emerged as one of the most promising ways for photo conversion-related technologies by harvesting sun light in environment and energy fields. In general photocatalytic oxidation has been applied broadly in the process of removal of organic pollutants in water and air as a cost-effective and environmentally friendly technology, which could decompose organic compounds into CO2 and H2O under lenitive conditions. The optimal

based on their respective oxidation states. Periodic trends suggest that group 14 oxidation states are normally - 4 as it is increasingly energetically favorable for them to accept electrons in order to complete their valence shells 3. However, due to the metallic properties of tin and lead, they generally lose electrons and therefore have a positive oxidation state. It is a characteristic trend to see heavier elements of the p block forming compounds in which their oxidation number is 2 (less than

Study of the oxidation of 3,5-di-tert-butylcatechol with molecular oxygen catalyzed by of 5, 10, 15, 20-tetraphenylporphyrinatocobalt(II). M. Hassanein, S. El-Khalafy*, S. Shendy Tanta University, Faculty of Science, Department of Chemistry, Tanta 31527, Egypt. Abstract 5, 10, 15, 20-tetraphenylporphyrinatocobalt(II) showed good catalytic activity towards oxidation of 3,5-di-tert-butylcatechol to 3,5-di-tert-butyl-benzoquinone by dioxygen in dimethylformamide. The oxidation reaction was followed

My FFA Life Unlike many teenage boys in highschool I’m apart of our FFA program. I’m in several ag classes including both shop, and welding class. I can pretty much weld anything and everything. It doesn’t matter what it is, I can weld it. This is one of the many things I enjoy in my life. No matter if my day is going bad that’s what I get to look forward to. If I could do this Monday through Sunday I totally would. It all started when my ag teacher asked me why I wasn’t in any of his ag classes

Introduction NyL Thompson is a 20 year old Junior Social Work major. She attends a Historically Black University. She resides off campus in her own apartment. NyL grew up in a supportive and loving home which consisted of herself, her older brother & sister, her mother, and her step father. When NyL was in the fourth grade she moved from the only home, school, and friends she had ever know and into a new neighborhood and school, she did not understand why her mother would do such a thing and began

What is Aged coffee? Recently, there has been an increase in aging of coffee. According to the saying, “Aged wine looks great, Aged whiskey taste good so is aged coffee.” The saying is not all about aged coffee or aged whiskey. Also, aged coffee is not that exceptional, and it does not deserve the credit. Here is the history, hype, and truth about aged coffee. The History of Aged Coffee Coffee was introduced to Europe in the mid-1500’s, it was referred to as aged coffee. During that period, Mocha
