Organic Chemistry Labs: Wittg Synthesis Of 1,4-Diphenyl-1,3-Butadiene
http://ochemisty.blogspot.com/2009/03/wittg-synthesis-of-14-diphenyl-13.html
Organic chemistry labs. University at Buffalo. Monday, March 30, 2009. Wittg Synthesis Of 1,4-Diphenyl-1,3-Butadiene. The purpose of this experiment was synthesize 1,4-Diphenyl-1,3-butadiene from benzyl triphenylphosphonium chloride and pure trans-cinnamaldehyde using Wittig reaction process to convert the carbonyl group in trans-cinnamaldehyde into a carbon carbon double bond. Below is the percent yield of the product obtained :. 1mmol )/(206.29g/mol) = 0.206grams of 1,4-Diphenyl-1,3-butadiene. The lowe...
Organic Chemistry Labs: Nitration of Naphthalene
http://ochemisty.blogspot.com/2009/03/nitration-of-naphthalene.html
Organic chemistry labs. University at Buffalo. Wednesday, March 25, 2009. The purpose of this experiment was to nitrate naphthalene with nitronium ion, which is formed at low concentration from a reaction of nitric acid and sulfuric acid. Naphthalene is a house product used. The major product from the reaction is the kinetic product, the one that forms the more stable cabocation intermediate. The mixture was cooled in ice and the product was collected by vacuum filteration. 0.1 of the crude produ...Moles...
Organic Chemistry Labs: Preparation of Para Red and Related Azo dyes
http://ochemisty.blogspot.com/2009/04/preparation-of-para-red-and-related-azo.html
Organic chemistry labs. University at Buffalo. Wednesday, April 8, 2009. Preparation of Para Red and Related Azo dyes. The purpose of this lab was to prepare two azo dyes, para red using a reaction of p-nitroaniline and 2-naphthol, and a related azo dye. Para dye is a chemical dye used in printing. It dyes cellulose fabrics to red. Reaction diagram for the other azo dye is missing]. The reaction yielded the desired product, para red, a red colored dye with the use of p-nitroaniline and 2-naphthol.
Organic Chemistry Labs: Synthesis of N,N-Diethyl-Meta-Toluamide
http://ochemisty.blogspot.com/2009/04/synthesis-of-nn-diethyl-meta-toluamide.html
Organic chemistry labs. University at Buffalo. Monday, April 13, 2009. Synthesis of N,N-Diethyl-Meta-Toluamide. The purpose of this lab was to synthesize N,N-Diethyl-meta-toluamide (DEET) using the m-methylbenzyoic acid and diethylamine. DEET is the most active ingredient in insect repellents. It is used to protect the skin from insect bites. The final weight obtained of the product, N,N-Diethyl-meta-toluamide, was 0.25grams. The theoretical weight of N,N-Diethyl-meta-toluamide :. The synthesis of N,N-Di...
Organic Chemistry Labs: Synthesis of Triphenylmethanol
http://ochemisty.blogspot.com/2009/03/synthesis-of-triphenylmethanol.html
Organic chemistry labs. University at Buffalo. Monday, March 16, 2009. Purpose of this experiment:. The purpose of this experiment was to synthesize triphenylmethanol. Triphenylmethanol is a white crystalline aromatic compound, which produces an intensely yellow color in a strong acidic solution due to formation of carbocation. Grignard reaction technique was used in this synthesis. The reaction was transferred to a centrifuge tube using a small amount of solvent-grade ether, leaving the stirr bar and an...

Размисли на един пенсиониран професор по органична химия. Неделя, 5 юли 2015 г. На В Г. (1980 г.). Не се отдалечавай,. Когато весело си бъбрим,. А ти си в някакъв. Не се отдалечавай,. И твоята кристална чаша. Не в звън,. А в призрак се превръща. Не се отдалечавай,. От спомена за твойта близост. Не се отдалечавай,. Които вчера съм докосвал. Не се отдалечавай,. Когато тихо те разтърсвам. Със ударите на сърце,. Притиснато до теб,. Макар ти никога да не го чувстваш. Не се отдалечавай,. Не се отдалечавай,.
