Engineering and Chemistry Muralla St.‚ Intramuros‚ Manila Melting Point and Boiling Point of Organic Compounds Group No. 5 Manacup‚ Cris Vincent L. Oblena‚ Adrian D. Ong‚ Joshua Jyro B.* *Leader ABSTRACT In compounds‚ two of the physical properties affected by the varying structures are melting point and boiling point. Through the use of the Thomas-Hoover Melting Point Apparatus or the micro method‚ the melting and boiling point of organic compounds are now determined. The aim of this experiment

temperature at which movement of the specimen is observed is recorded as the pour point. INTRODUCTION In the cloud point experiment‚ waxes will appear and thickens the oil and clogs fuel filter and injectors in engines. The wax also accumulates on the cold surfaces and forms an emulsion with water. The appearances of cloud point determine the first cloud of wax crystals in a liquid when it is cooled. Whereas‚ pour point experiment is to determine the minimum temperature of the oil which will continue
