The first synthetic sweetener‚ saccharin‚ was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately seven years after it’s discovery‚ J.D. Reidel‚ of Berlin‚ was able to synthesis Dulcin at a reasonable cost. Once it became possible to synthesis at a reasonable cost‚ mass production of the sweetener began. Dulcin was favored over its competitor‚ Saccharin‚ because it did not possess a bitter aftertaste. For a very brief period of time Dulcin was marketed

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 is not expensive and can easily be removed for the reaction. The acetic acid

In the 5th century B.C.‚ Hippocrates ground the bark into a powder‚ and later‚ the Natives Americans chewed on the bark to alleviate fever and pain1. In the 19th century‚ a German chemist by the name of Felix Hoffman wanted to find a medication that would ease

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

Alum Synthesis: The Chemical Process of Recycling Aluminum Introduction By recycling aluminum cans‚ the costs and energy savings are dramatically more resourceful and efficient than producing aluminum from what it is naturally found in‚ bauxite ore. The process of recycling aluminum to produce potassium aluminum sulfate‚ a common alum‚ will be done through a serious of chemical reactions. Through this reaction‚ percent yield will be determined.

That is the sentence that defines what the teenagers’ worth to the country is. We are supposed to change what the country is now. But the question is . . . Can we? From what I observed is happening now‚ instead of being the country’s biggest hope‚ we seem to be one of its burdens. There’s pre-marital sex‚ prostitution‚ juvenile delinquencies‚ and the list

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
