GAS OIL FRACTION FROM ANKLESWAR CRUDE - INFLUENCE OF ACTIVATORS AND DILUENTS ON THE UREA ADDUCTION

The effectiveness of some compounds such as alcohols, acids, ketones a nd amides etc. to act as activator in the formation of inclusion compo unds between urea and n-alkanes present in a gas oil fraction (200-350 -degrees-C) derived from Ankleswar crude oil has been studied. It has been observed that the effectiveness of the activators is greatly infl uenced by the concentration, the type of hydrogen bonding and solubili ty parameter (delta)/molar volume of the activator and is also a funct ion of the nature of the solvent used. Also, for the above gas oil fra ction N-methylformamide has been found to be a better activator than m ethanol which uptil now has been reported to be the most effective act ivator.
