The following is a modification of previously reported methods. 3‚4-Diaminothiophene (2.85g‚ 25 mmol) was dissolved in 20mL of absolute ethanol. Diethyl oxalate (30mL‚ 220 mmol) was added to the solution. The reaction mixture was refluxed for 8h. After the reaction mixture cooled to room temperature‚ the solid residue was recovered by vacuum filtration. The

Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

Ether is an anesthetic that works on the brain and puts it to sleep. The same symptoms operating patient experiences under ether are those experienced by a person drinking alcohol.intro Ethanol is commercially produced using a process called fermentation. Many other alcohols can be made this way‚ but are more likely
