filtered and recrystallised from ethanol. 4.6.General procedure for Preparation of the N-methylation of piperidin-4-one oximes: The piperidone (0.1mol)was dissolved in ethanol(50ml). saturated solutions of hydroxylamine hydrochloride and sodium acetate in water were added. The mixture was refluxed on a water bath for one hour. Then it was cooled ‚ poured into water and the solidoxime obtained was filtered. All the oximes were recrystallised from ethanol. S.

Abstract: The goal of this experiment was to synthesize aspirin. In this experiment aspirin‚ also known as acetylsalicylic acid‚ was synthesized from salicylic acid and acetic anhydride. In the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group. This method of forming acetylsalicylic acid is an esterification reaction. Since this esterification reaction is not spontaneous‚ sulfuric acid was used as a catalyst to initiate

gathered near the Lincoln Park conservatory. Materials and Methods: For data collection of insects‚ the class went to the North Pond Nature Sanctuary. A large and small net were used to catch various insects. Gauze that was previously soaked in ethyl acetate was used inside of a sealed glass jar to euthanize the insects that were caught. The insects were then placed into a ziplock bag to be stored in a freezer to preserve DNA structure. Environmental data was also collected regarding each insect
