Melting Point and Boiling Point of Organic Compounds Bongo‚ Sayre‚ J1 1Student‚ Organic Chemistry 1 Laboratory / B11‚ School of Chemical Engineering‚ Chemistry and Biotechnology‚ Mapúa Institute of Technology ABSTRACT The melting point of a substance is the temperature at which the material changes from a solid to a liquid state while the boiling point is the temperature at which it changes from liquid to solid. In this experiment‚ the main objectives were to determine the effects of the following

Following standard procedures and using the resulting aldehyde‚ along with 2‚4-dimethylpyrole‚ a BODIPY dye was obtained [36]. To facilitate intersystem crossing‚ the 2- and 6- positions of the boradiazaindacene ring system were iodinated with

understanding of the scientific applications surrounding Tetraphenylporphyrin (TPP). In order to generate TPP‚ the group has elected to use the procedure outlined in Bozak & Hill. This requires adding equal parts of distilled pyrrole and reagent grade benzaldehyde together in a round bottom flask in propionic acid. This solution is then refluxed for about 30 minutes and the precipitate is dried by suction filtration. This product will be analyzed and classified by UV-Vis‚ FT-IR‚ and H1 FT-NMR. Once the product

Infrared Spectroscopy Organic Chemistry Lab 301A B. The purpose of this lab is to study Infrared Spectroscopy‚ which focuses on the study of the electromagnetic spectrum. The area to be studied is the infrared region‚ which is made up of gamma‚ X‚ and UV rays. We want to be able to identify spectra’s to their complementary structures. The background of this experiment particularly deals with the study of compound structure determination‚ and traits. We must be aware of the functional groups
