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).

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
