Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

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

Modeling nature Task 1 Theory construction and Model-building skills (chapter 1-3) Scientific research is a process that is designed to extend our understandings and to determine if they are correct or useful. Science strives to operate according to a more rigorous set of rules. Realism: reality exists independent of any human presence‚ there is an external world comprised of objects that follow a myriad of natural facts and laws. --> mirror world.

Paper 2-Explanatory Synthesis Obesity and the overall public health are becoming increasingly large problems America. Many people are split on ideas as to what is causing this health crisis. “Don’t Blame the Eater” by David Zinczenko‚ and “What You Eat Is Your Business” by Radley Balko are two essays that discuss problems with the current system as well as potential solutions to these problems. While Zinczenko argues that the problem is coming from a lack of information on the products being consumed

The American Dream‚ a dream that all Americans have‚ for everything to be equal‚ and to have life‚ liberty‚ and the pursuit of happiness. This is the typical American dream and the overall outline of the American Dream but everyone’s can be significantly different. In the book of mice and men the lesson you learn is that just having an American Dream is what shapes your life and gives you the purpose to do things. Whereas in The Great Gatsby the lesson is more along the lines of showing you that

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

Plato vs aristotle theory of knowledge The theory of knowledge (Epistemology) is the philosophical study of the nature‚ scope and limitation of what constitutes knowledge‚ its acquisition and analysis. The fundamental issue that remains unsolved in epistemology is the definition of knowledge. Philosophers are divided on this issue with some analyzing it as justified true beliefs while others differ and say that justified true belief does not constitute knowledge. The objective of this paper is to

Sigmund Freud and B.F. Skinner One name that jumps out at the mention of psychology‚ or the study there of‚ is the name of Sigmund Freud. Sigmund Freud is also known as the “Father of Psychoanalysis.” Freud was also known for having the tendency to trace nearly all psychological problems back to sexual issues. Although only parts of his theory of psychosexual development are still accepted by mainstream psychologists‚ Freud’s theory of the Oedipal Complex has become a cultural icon (Freud‚ Sigmund

September 2013 Social Control Theory vs. Self-Control Theory According to the idea of control theories‚ an individual who has for some reason or another cut ties with the “conventional order” so that he or she is now free to commit any criminal or deviant acts (Cullen & Agnew‚ 2011 P216). Travis Hirschi‚ in 1969‚ created the Social Bond Theory of crime‚ aka Social Control theory; two decades later he joined Michael Gottfredson to create the Self-Control Theory. It seems that‚ over time‚ Hirschi’s
