The goals of this experiment are to determine if the products derived from amide synthesis and Williamson Ether Synthesis are identical‚ and if one of the synthetic routes is more advantageous than the other. In Part 1‚ an attempt to synthesize acteophenetidin crystals by amide synthesis was made. We began by removing the colored impurities from the p-Phenetidine (reddish-brown) by placing 2g of the sample in 38 mL of hydrochloric acid and heating the solution to boiling point. Upon reaching just

Today we have a serious problem with pollution‚ resulting not only soil contamination‚ environmental‚ noise or air‚ we can significantly reduce this impact all being aware and knowing that recycling is reuse; if we make a daily habit will give more life to our planet.
