Introduction In this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic

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

[pic] Trimyristin (glyceryl trimyristate) is a triglyceride easily obtained from nutmeg by extraction with boiling ether (3). Saponification of trimyristin produces the salt of myristic acid (CH3-(CH2)12-CO2Na) (3)‚ which is a soap (4).

1. Provide a general discussion of the solubility/miscibility behavior observed in procedure A-D. For part A of the procedure we worked with the solubility of solid compounds in various solvents. The three solid compounds that were worked with during this procedure were benzophenone‚ malonic acid‚ and biphenyl. These three solids were then mixed with water (highly polar)‚ methyl alcohol (intermediately polar)‚ and hexanes (nonpolar). When benzophenone is mixed with water the results turned out to

Finally‚ addition of diethyl ether to the mixture then distillation took place to be purified and to obtain the final product‚ cyclohexanol (McFadden‚ 2012). Diethyl ether was used to extract alcohol from salt-water mixture because diethyl ethers solubility in water is lower than cyclohexanol which helps remove alcohol from the salt-water mixture (Merzougui‚ A‚ et al.‚ 2011).

Diethyl ether‚ dichloromethane (methylene chloride)‚ trichloromethane (chloroform)‚ pentane‚ hexane‚ petroleum ether are some of the solvents commonly used for extracting aqueous solutions. Petroleum ether and ligroin are mixtures of hydrocarbons whereas the other liquids mentioned earlier are pure substances. The most excellent liquid for extracting organic solutes is diethyl ether.
