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

Alum Synthesis: The Chemical Process of Recycling Aluminum Introduction By recycling aluminum cans‚ the costs and energy savings are dramatically more resourceful and efficient than producing aluminum from what it is naturally found in‚ bauxite ore. The process of recycling aluminum to produce potassium aluminum sulfate‚ a common alum‚ will be done through a serious of chemical reactions. Through this reaction‚ percent yield will be determined. Materials and Methods The mass of a 250 mL

But I’ll tell you‚ anyway. She was some sort of dumb they say. I don’t care. I loved her. And I still miss her; it’s just that I don’t know how to get there fast. All I know is that she won’t let me… It sure is hot today‚ and I still need to go pick up the groceries Anne bought. Anne is our maid

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

In modern day‚ man does not truly think about how much the earth means to life. On the contrary‚ humans aspire to cease Mother Nature’s beauty with the replacement of modern day cities made up of synthetic nature. Since the dawn of the twentieth century‚ a major theme in the American Arts has been the protest against man’s destruction of the natural world. With this in mind‚ as very well argued in Chief Seattle’s article “Respect”‚ humans fail to be conscious of the physical and sentimental value
