Synthesis of Methyl Salicylate from Aspirin Esters are a class of organic compounds. An ester compromises an organic or inorganic acid in which one or more hydroxy (OH) groups have been replaced by and alkoxy (O-alkyl) group. For example‚ the simplest ester‚ methyl formate (CHOOCH3)‚ is made up of formic acid (CHO-OH) in which the hydroxyl group has been replaced by a methoxy group (-OCH3). Similarly‚ ethyl acetate (CH3CO-OCH2CH3) is made up of acetic acid (CH3CO-OH) in which the hydroxy group

this experiment using 10mL solutions of phenol red with concentrations 10µM‚ 7.5 µM‚ 5.0 µM and 2.5 µM then the absorbance of each sample was measured using a spectrophotometer. This generated curve with resulting average absorbances of 1.273nm‚ 1.0275nm‚ 0.585nm‚ 0.285nm and 0.124nm provided a means to determine the phenol red concentrations of two unknown samples after experimentally identifying the absorbance of the two samples using a spectrophotometer. 2.

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

Synthesis Conclusion: Conclusion: As we can see‚ the sources show us that during the Enlightenment period money was very important. It shows that during the time people would do merely anything for money‚ even force their children into arranged marriages or‚ as Voltaire suggest satirically‚ sell them as a food source. Parents or even the brides and grooms themselves would arranged marriages for economic gain. This was not always the case. We have learned from She Stoops to Conquer that‚ although

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared
