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 An ester compromises an organic or inorganic acid in which one or more hydroxy (OH) groups have been replaced by and alkoxy (O-alkyl) group.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the simplest ester‚ methyl formate (CHOOCH3)‚ is made up of formic acid (CHO-OH) in which the hydroxyl group has been replaced by a methoxy group (-OCH3).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

Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion

Synthesis Paper Introduction Exercise can be very challenging to commit to. As a young adult my ideas and hopes were to always begin and maintain a routine that would help me to stay active and healthy. I regretfully report that I have not yet committed to this effort. In high school‚ I ran with the track team and was faithful the Reserve Officer Training Corps which helped me to stay in shape and remain fit with much effort. This was just a part of my life and I enjoyed it

Synthesis Essay The Puritans dream was to create a model society for the rest of the Christians. Their goal was to make a society in every way connected to god. But to really understand what the aspirations of the puritans were‚ we must first understand their beliefs. These beliefs were expressed through their writings which have been read through the years by American students.
