Synthesis of Aspirin from Oil of Wintergreen Objectives: In this experiment‚ the Oil of Wintergreen is put into an Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. The solution is then refluxed which means that the solution will be boiled in a base‚ then condensed in a condenser. This replaces the carbon on the ester at carbon 1‚ with an oxygen atom which will have an ionic bond with a sodium anion. This yields sodium salicylate which will be acidified in methanol

Emulsification of Oil Prepared for: Mrs. Elena Gallagher By: Anna Villanella March 25‚ 2014 Oil is a nonpolar molecule. Polar molecules have charged groups or atoms. Nonpolar molecules have no charged groups or atoms. Polar molecules‚ like water‚ are good solvents for other polar molecules. This means they molecules that react with the water disperse into the water. Nonpolar molecules don’t disperse in water because nonpolar molecules and polar molecules don’t interact.

of the ’Peak Oil’ theory‚ the world is expected to face severe oil shortages in the near future. Then‚ how can mankind meet its energy needs? Peak oil is the point in time when the maximum rate of global petroleum extraction is reached‚ after which the rate of production enters terminal decline. The concept is based on the observed production rates of individual oil wells‚ and the combined production rate of a field of related oil wells. The aggregate production rate from an oil field over time
