CHEMISTRY 101.1 Intermediate Chemistry Laboratory I Institute of Chemistry University of the Philippines‚ Diliman I. Synthesis of Salicylic Acid Purpose: Part I of the experiment illustrates the base hydrolysis of an ester‚ methyl salicylate‚ to form salicylic acid through nucleophilic acyl substitution. Procedure: Dissolve 12 g NaOH in 70 mL water in a 150 mL round bottom flask. Add 5.0 mL methyl salicylate and reflux the reaction mixture at its boiling point for 15 minutes using a stirrer

aqueous solution of formaldehyde is called formalin. The commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen

Toni Morrison‚ the author of “Sula‚” used the tradition of African naming numerous times throughout the entirety of her novel. With names ranging from Eva to BoyBoy‚ there are a profuse amount of ways to interpret the meaning behind her writing style and name selecting. Her characters Helene‚ Eva‚ and BoyBoy have the most prevalent parallels to African naming traditions. Once Helena married Wiley Wright‚ they relocated to a residence in Medallion. The people of ‘The Bottom’ then omitted the e from

Synthesis Essay In today’s society‚ language is one of the most important and most used things in everyday life. Language is one of the most effective and efficient ways of communicating with one another‚ animals‚ and God. It can be used as a mirror‚ tool‚ or a weapon. The reason I think language can be used as a mirror is because people use language to directly reflect who they are as a person. For example‚ if you have heard someone using improper grammar or slang‚ it may lead you to believe

Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized
