Abstract

The use of IR spectrophotometer for the estimation of four physical properties ( RON, Δ Hf0 , Molecular mass Mr. and Specific gravity ρ ),simultaneously in hydrocarbon mixtures. IR absorption spectrum can be used to provide information, that can be obtained by several existing test methods .percentage of standard error 9 for RON ,1.8 for specific gravity,2.5 for molecular mass and 2.28 Kcal/ mol for heat of formation .
