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

A Struggle to Learn From the time when I was a little boy‚ growing up in Graves County‚ Kentucky‚ I have had problems with my reading and writing. Things never seemed to click for me‚ a trait that the teachers attributed to a mild case of dyslexia mixed with a healthy dose of attention deficit disorder. I knew‚ however‚ that no disorder was the cause of my distaste of reading and writing. Rather‚ there was nothing really interesting surrounding me that would grab my interest in the classroom

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

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

Synthesis of Information In summary‚ the articles researched were divided into four main categories. The categories all focused on something different. The categories were; the perception kids have on food‚ communities raising healthy kids‚ nutritional awareness and the school context. The first two articles had the common theme of how children view food and to find what children thought and felt about healthy food. The third article was aimed towards parents. The theme of this article was how
