    the different chemical properties of each compound. We will accomplish this by a separation procedure known as distillation‚ which relies on each compound having a distinct and separate boiling point. Our pure products will be analyzed with gas chromatography to determine the success of the distillation. Procedures The experiment was performed as stated in the course textbook: Pavia‚ D.

    that might need this purification setup. Experimental Procedure: This lab follows the experimental procedure of the book as outline in the Mayo book on pages 133 and 134. However; the following modification were made to the procedure: Use gas chromatography instead of refractive index Collect GC for only fraction 1 and fraction 3 because of time constraints.

    Page 2 Europe Page 4 Conclusion Page 5 References Page 6 Summary Natural gas markets are different unlike oil‚ they are categorized under regions. This is due the fact that natural gas sources are found far away from the consumers and the cost of transportation of natural gas is high over long distances. However‚ the cost of domestic consumption is also high due to high capital required for investment. Natural gas has three main markets which are located in Europe‚ North America and Asia; with
