Anesthetic ether is the actually diethyl ether CH3CH2OCH2CH3. It has been used as an anesthetic in medical surgery for over 150 years‚ though the hypnotic effects of ether was already discovered 500 years ago. The historical development of ether anesthesia is very dramatic and interesting. Ether anesthesia: The historical development Ether was discovered in 1275 by Spanish chemist Raymundus Lullius‚ and was named ¡§sweet vitriol." In 1540‚ a German scientist Valerius Cordus described the synthesis

rhetorical analysis‚ and synthesis‚ instructed by Dr. Tina Giovanielli. Although I believe all four arguments were strong‚ for the purpose of this reflective assignment I am going to choose one argument that I think is my strongest piece of writing then analyze it and explain why I think that is my best work. I believe my last assignment (synthesis) was very challenging at first but it ended up to be my strongest piece in the whole semester. Since I have never done any synthesis before this one‚ I found

Multistep Synthesis of Benzilic Acid The synthesis of several complex organic compounds follows a multistep synthesis. "Multistep synthesis" refers to the procedure in which the product of one reaction serves as the starting material in the subsequent reaction. The multistep synthesis of benzilic acid begins with a conversion benzaldehyde to benzoin through a condensation reaction. The benzoin then oxidizes into benzil‚ which undergoes rearrangement to give benzilic acid. Benzoin Synthesis * When

5.4. Synthesis of Poly L-Lactide (PLA) PLA was synthesized by the ring opening polymerization of L-Lactide in presence of stannous octoate. L-Lactide (1.44 g (0.01 mol)) was dissolved in 20 mL of toluene; 1.5 mg of stannous octoate was added to this solution. The mixture was refluxed under continuous stream of nitrogen at 110ºC for 12 h. A white product was obtained. The product was dissolved in 15 mL of chloroform and an excess of cold ether (~32 mL) was added to the solution

Synthesis of Aspirin Ling Tecson Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order

unconscious mind He thought that a large part of the mind is non-accessible and is completely hidden. He referred it as the unconscious mind. The unconscious mind may contain something that is repressed by a person to help him forget or to avoid from facing it in reality. The conscious mind tends to push or repress something into the unconscious part of his mind. People may not be aware of the “secrets” they were repressing into their unconscious mind as they do not deliberating repress those
