OXIDATION PRODUCTS IN AN OXYGEN-BLOWN KUWAIT ASPHALT

A KUWAIT ASPHALT FLUX, WHICH IS ORDINARILY VERY DIFFICULT TO HARDEN BY AN AIR-BLOWING PROCESS, WAS TREATED WITH OXYGEN TO PREPARE A COATING-GRADE ASPHALT. OXIDATIVE CHANGES WERE MEASURED BY INCREASE IN SOFTENING POINT AND BY INFRARED SPECTROSCOPY. THE INFRARED SPECTRA OF THE COATING-GRADE ASPHALT TO WHICH MODEL ORGANIC COMPOUNDS WERE ADDED WERE COMPARED WITH SPECTRUM OF THE ORIGINAL ASPHALT. THE PRINCIPAL OXYGEN-CONTAINING PRODUCTS FORMED DURING OXIDATION AND PHOTOOXIDATION, AS ASSIGNED BY INFRARED ANALYSIS AND SEVERAL COLORIMETRIC METHODS, WERE ACIDS, ALDEHYDES, KETONES, AND PEROXIDES, WHICH CONFIRMED PREVIOUS FINDINGS WITH ASPHALTS FROM OTHER GEOGRAPHICAL SOURCES. /AUTHOR/
