The goals of this experiment are to determine if the products derived from amide synthesis and Williamson Ether Synthesis are identical‚ and if one of the synthetic routes is more advantageous than the other. In Part 1‚ an attempt to synthesize acteophenetidin crystals by amide synthesis was made. We began by removing the colored impurities from the p-Phenetidine (reddish-brown) by placing 2g of the sample in 38 mL of hydrochloric acid and heating the solution to boiling point. Upon reaching just

Bankruptcy: Its Prediction and Accounting Indicators One major assumption in accounting is the Going Concern. It states that an accounting entity is viewed as continuing in operation indefinitely‚ thus‚ financial statements are normally prepared in the assumption that the entity will continue its operations for the forseeable future. But then it is inevitable that one shall come to an end. So if there is evidence that the entity’s operations are to be terminated‚ the going concern assumption

Social scientists have studied it‚ lawyers have tried to fix it and post-feminist society is over it. But women are still outnumbered by men in math‚ science and engineering fields. Most overt discrimination against women in the sciences has been reduced or eliminated in recent decades through legal‚ academic‚ corporate and government measures. But a climate that is less than fully friendly to women remains‚ and its texture is often still so taken for granted that it tends to be invisible. The

this essay‚ I will briefly review the history‚ definition of Green IT‚ approaches to implement green IT with examples‚ benefits and costs of Green IT. History and Definition of Green IT History of Green IT started with energy star program in 1992 which was designed to encourage and recognize the energy efficiency in the monitors and printing product. Green IT was emerged shortly after the energy star program and the goals of green IT are to reduce the use of hazardous materials‚ maximize energy

Green Technology: Future of power generation NEED FOR GREEN TECHNOLOGY Recently concluded Copenhagen conference on climate change and green house emission expressed concern over the amount of CO2 being released. This would in turn heat up the atmosphere and cause global warming that will result in the melting of glaciers and hence the sea level will rise that is a threat to several coastal cities of the world. So one can imagine how the amount of CO2 emissions can cause problems of displacing

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

What is green building? As the global climate warming‚ more and more people focus on building energy efficiency. There is more awareness that CO2 produced by building energy use is the main source of climate warming. Energy-saving buildings become inevitable trend of development‚ the green building also arises in time. Green building can be define as to the construction of the whole life cycle‚ for maximize resource conservation (epa.gov‚ 19/12/2012). It includes energy saving‚ land saving‚ water

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

CHEM3412 Synthesis of a Porphyrin Porphyrins are hetereonuclear‚ macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants‚ chlorophyll uses the vast conjugation to allow absorption of light for photosynthesis. The characteristic colors of porphyrins is also due to the conjugation. An examination of the porphyrin structure
