Introduction Organic compounds are categorized by their physical properties and/or chemical reactions. Naphthalene is classified as an aromatic hydrocarbon that consists of two benzene rings that are fused together. Its physical …show more content…
The samples were then attached to a thermometer and placed in a Thiele tube filled with oil. The tube was heated by a Bunsen burner at approximately 1 °C per minute. Melting point temperatures were recorded at the first indication of fluid and then when the sample had turned completely liquid. Two trials were completed on each sample ². The melting point of 10% naphthalene / 90% Biphenyl mixture was determined by electronic instrumentation. Two samples were prepared and placed in closed end capillary tubes and then inserted into the "Mel-Temp" device beginning at 30°C and set at 22 volts to ensure gradual heating; approximately 1°C per minute. Two trials were completed on each sample. The results were then categorized and combined with other data sets collected by the laboratory students. This data was then used to find the eutectic point of the two substances
