Abstract: All the materials were measured and weighed. It was found in the experiment that the yield of copper hydroxide in 40%. Introduction: The copper (II) sulphate is then placed in 100 mL of distilled water. Then 20 mL of CuSO4 is measured and placed 100 mL of distilled water. This can later be weighed to determine the mol of CuSO4 and the mol/L concentration. Then this was used to find out how many mL of 0.5 NaOH solution is needed to react completely with all the copper (II)

Megan Wierzbowski Organic II Laboratory Wed. 11-1:50 Title: Grignard Reaction with a Ketone: Triphenylmethanol Part 1 Objective: The goal of this experiment is to learn to make Grignard reagents. The reactions of the Grignard reagents with ketones form tertiary alcohols. These reagents are highly air- and moisture-sensitive materials. We will observe the formation of the Grignard reagents‚ which magnesium metal is transformed into organometallic salts. Experimental Procedure:

I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

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

Airline News Express airline NEws Express We Report to you In This Issue: Airline Yield Management The practice of Yield management has been widely adopted by service organizations in the past three decades. Yield management originally started in the airline industry and this capacity management strategy is also most often applied by airlines. The practice of yield management‚ especially in the airline industry‚ has been discussed in many different studies. There is‚ however
