be found in other organisms. The purpose of this lab was to synthesize the ester isopentyl acetate via an acid catalyzed esterification (Fischer Esterification) of acetic acid with isopentyl alcohol. Emil Fischer and Arthur Speier were the pioneers of this reaction referred to as Fischer Esterification. The reaction is characterized by the combining of an alcohol and an acid (with an acid catalyst) to yield and ester plus water. In order to accomplish the reaction‚ the reactants were refluxed for

for my theater course. I saw a play that was set in 1904 at 1839 Wylie Avenue in Pittsburgh‚ Pennsylvania. Aunt Ester who lives on 1839 Wylie Avenue with Black Mary‚ Aunt Ester maid‚ welcomes Solly Two Kings and Citizen into her home. Citizen is from Alabama is in search for a new life and is asking help from Aunt Ester. He is in need of redemption from his past. In the play‚ Aunt Ester takes him to a spiritual awakening to the City of Bones. The play was about two hours long with a ten-minute intermission

Raisio’s Research and Development program further developed a medical use of a byproduct of pine-wood pulp or stanol ester. Raisio had found a unique way of processing the plant stanol which allowed it to become refined and fat-soluble. They studied it further and found it to have a profound cholesterol-reducing effect when consumed. The findings were published in New England Journal of Medicine in November 1995; “after a 14-month trial‚ a daily intake of 25 grams reduces total cholesterol in

The present invention relates to polyvinyl chloride plastisol compositions‚ for example sealant compositions. In the manufacture of automobiles‚ the automobile body is initially primed with a coating composition to prevent corrosion of the metal. This can be done in a number of ways although generally it is performed by cationic electrodeposition using the auto body as the cathode. Once the automobile body has been primed in this manner‚ subsequent steps in the assembly are carried out. These

Then‚ ketene was reacted with a chiral and nonracemic (S)-ethyl lactate produces a mixture of diasteromeric esters of ibuprofen derivatives where (S) configuration is predominantly. Finally‚ hydrolysis of the ester then provides (S)-ibuprofen in a relatively high yield. all reaction were monitored by TLC at room temperature with appropriate solvent system which states in experiment section.

commercial light stick there is a mixture of hydrogen peroxide solution and a solution containing a phenyl oxalate ester and a fluorescent dye. Here’s the sequence of events when the two solutions are combined: 1. The hydrogen peroxide oxidizes the phenyl oxalate ester‚ resulting in a chemical called phenol and an unstable peroxyacid ester. 2. The unstable peroxyacid ester decomposes‚ resulting in additional phenol and a cyclic peroxy compound. 3. The cyclic peroxy compound decomposes

purified product identified the Arene strand of 2969.71 indicating C-H stretch. Ester which indicated a C=O stretch of a 1750-1735. Aliphatic amines showed an absorption band of 1217.62 indicating a C-N stretch. (This makes no sense‚ look at the molecule you have and relate the points. Furthermore‚ you need to compare your results to a literature source) An example of a practical application would be using the ester to produce flavors in products. It could be used in a laboratory where they are trying
