...Chapter 22- Oxidation Reaction: Cyclohexanol to Cyclohexanone Carlos E. Gonzales (William Bridges) March 18, 2015 CHM 246, Sec L02B Purpose The oxidation of a secondary alcohol to a ketone is accomplished by many different oxidizing agents, including sodium dichromate, pyridinium chlorochromate, and sodium hypochlorite (household bleach). In this experiment, we use sodium hypochlorite because it is much safer from an environmental standpoint. The mechanism of the reaction is not clear. It is not a free radical reaction, the reaction is much faster in acid than in base, elemental chlorine is presumably the oxidant, and hypochlorous acid must be present. It may form an intermediate alkyl hypochlorite ester, which by an E2 elimination gives the ketone and chloride ion. The purpose of this experiment is to oxidize an alcohol to a ketone with household bleach. The product is isolated by steam distillation and is extracted into the distillate with ether that is dried in a column of drying agents. Removal of the ether leaves the product cychohexanone. Theory Cyclohexanone is used as a precursor for nylon. This makes it one of the largest mass produced chemicals in the industry. Billions of kilograms of cyclohexanone are produced each year for the making of nylon. The synthesis of cyclohexanone is simple. First, sodium hypochlorite and acetic acid are reacted to yield hypochlorous acid. Second, hypochlorous acid is added to cyclohexanol to synthesize cyclohexanone. After...

...naturally occurring biological, geological, and man-made chemicals are capable or stabilizing the environment’s pH. This may allow organisms to better survive in diverse environments found throughout the earth. In this investigation, you will test a number of substances using pH paper and a pH electrode to determine pH values of household substances. You will also examine the difference between qualitative and quantitative data. Objectives In this experiment you will: • Add an acid to a material and note the changes in pH • Add a base to a material and note the changes in pH • Work with classmates to compare the ability of different materials to test pH [pic] Figure 1 Materials Computer Vernier computer interface LoggerPro Vernier pH sensor Paper towel Wash bottle with distilled water Goggles Beaker 24-well plate pH paper Procedure Part 1: pH tests using pH paper 1. Obtain and wear goggles. 2. Notice the 24-well plate is labeled with A-D for the rows and 1-6 for the columns. 3. Have ONE group member go to the back lab bench and fill the wells halfway with the various household substances. 4. Take a piece of the pH paper and touch it to the substance in well A1. 5.

...Vinegar as a battery of Calculator Uba, Terrence L. Navarro, Loyd V. Ebabacol, Ruben S. Baa, Margaux Eve P. Ompoc, Shamira Jasmine C. Submitted in partial fulfillment of the requirements in Research 1 Alubijid National Comprehensive High School Special Science Class Alubijid, Misamis Oriental January 8, 2014 Mrs. Ma. Romila D. Uy Research Adviser Abstract Battery is a device used to store electrical energy. Battery can also be called a cell in which the reaction between two different substances can be made to occur in such a way that some of the chemical energy is converted into a useful electricity. Since its invention and inception, battery has become the most common power source for many household and industries. The vinegar battery is constructed out from simple components or materials. Adding an amount of vinegar to a strip of different metals like copper, from copper wires and zinc, from nails can form a simple battery. This battery has a low amperage output which can supply power on a low amperage/low voltage device like a calculator. It is easy to construct. The following steps should be followed in constructing the vinegar battery: 1. Prepare all the materials needed like: * Vinegar * Strip of Zinc from nails * Strip of copper from copper wire * Vinegar container (non-metallic) * Multi-tester 2. Place the vinegar inside the container. Make sure that it is deep enough to suspend the two different metals on it. 3. Cut a piece of copper...

...\CONSUMER BEHAVIOUR Basic concepts and definition Objectives: By the end of this lesson you will be able to: Explain why marketing managers should understand consumer behavior Define and explain basic concepts in the study of consumer behavior. Introduction Why is it difficult to market any product to consumers? The reason is simple: Consumers are complex and constantly changing. Not only is it difficult to figure what marketing program will work but also what worked yesterday may not work today. Thus marketers must constantly improve their understanding of customers. Understanding consumer behavior and knowing your customers is never simple. Customers may say one thing but do another. They may not be in touch with their deeper motivation. They may respond to last minute influences. Some companies like Kenya Airways, Equity Bank, Microsoft, Coca-Cola e.t.c have stood to profit from understanding how and why their customers buy. On the other hand not understanding your customer’s motivations, needs and preferences can hurt. In Kenya, companies like Elliott’s and Sang Yong Motors failed. Consider also the case of Kodak when it introduced its Advantage camera and proudly marketed it as a high-tech product but to a generation (usually referred to as middle-aged baby comers) for which the bells and whistles of new technology had lost their appeal. It was a costly bust. Basic definitions and concepts Marketing: Just to remind ourselves we can say that...

IKEA AND THE NATURAL STEP In September 1995, Jan Kjellman took over as president of IKEA North America, the U.S. and Canadian subsidiary of the Swedish furniture giant. At IKEA s headquarters outside Philadelphia, Pennsylvania, Kjellman sat at his desk, located in an open, brightly sunlit bay. His assistant, also the service center office manager, sat at a nearby desk a few feet away. Co-workers walked through one side of the bay, heading for the coffee room. On the landing below the president s office was a pedestal bearing a large gray rock. It was from the rocky and poor land in ˜lmhult, a small village in the province of Sm land, Sweden, where IKEA s founder was born and...

...BACKGROUND TO PRINCIPLES OF MARKETING INTRODUCTION TO MARKETING Every business, service or product oriented organization must complete its operation by disposing of its products or rendering its services to the customers. Various marketing concepts hold that customers will generally not buy a product they don’t know or they have not been asked/convinced to buy. It is therefore the role of the marketing function in any business to fill this gap and complete the business operation. Definition of Marketing The Chartered Institute of Marketing of the United Kingdom defines marketing as, “The management process which identifies, anticipates, and supplies customer needs efficiently and profitably.” Kibera (1996) defines marketing as “the performance of business and non-business activities which attempt to satisfy a target individual or group needs and wants for mutual benefit or benefits.” Kotler (2006), the American marketing guru provides the definition of marketing as “A social and managerial process whereby individuals and groups obtain what they need and want through creating and exchanging products and value with others.” Kotler and Armstrong (2008) define marketing as “The process by which companies create value for customers and build strong customer relationships in order to capture value from customers in return.” Core Marketing Concepts 1. Needs – The basic concept underlying marketing is that of human needs. Needs comprise of those things...
