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).

The Colorado River Threats to river and delta: Water flow is decreasing. This water serves 30 million people in seven U.S. states and Mexico‚ with 70 percent of its water siphoned off to irrigate 3.5 million acres of cropland. Possible actions between the United States and Mexico could significantly reduce the flow of water into the delta‚ increase its salinity‚ and alter the natural vegetation. Drought has lowered water levels in upstream reservoirs‚ eliminating the occasional floods the delta
