Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

Peter Mehnert Rhet 105 Ms. Paterson 11/14/12 Extended Synthesis: Cigarette Smoking Tobacco has played an important role in America from the beginning. It was grown as a cash crop by the Jamestown settlers in 1612‚ but over the years the popular opinion has changed about tobacco. Tobacco is used to make cigarettes‚ which have been extremely popular‚ now known to be extremely dangerous. Even the warnings on the cigarette box have changed to a statement much more alarming. In the 1960s‚ the warning

Synthesis of Information In summary‚ the articles researched were divided into four main categories. The categories all focused on something different. The categories were; the perception kids have on food‚ communities raising healthy kids‚ nutritional awareness and the school context. The first two articles had the common theme of how children view food and to find what children thought and felt about healthy food. The third article was aimed towards parents. The theme of this article was how

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.

Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment‚ we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C‚ therefore our percent

agent for rabies. The rabies virus is enveloped‚ it is covered/surrounded by a covering for protection. The rhabdovirus contains up of a helical ribonucleoprotein core(RNP)‚ and an envelope that is surrounding the viru (CDC‚2011). Eukaryotes have a synthesis process between protein and RNA that forms the ribonucleoprotein. The rabies genome has five protein components: nucleoprotein‚ phosphoprotein‚ matrix protein‚ glycoprotein‚ and polymerase protein(CDC‚2011).
