Pagination or Media Count:
A petroleum fraction of 370-500 degrees contained 23 mono and bicyclic aromatic hydrocarbons, which were used to obtain sulfonated additives. The hydrocarbons were obtained by separating the polycyclic aromatic hydrocarbons with N greater than 1.57. Oil soluble additives were prepared by sulfonating the hydrocarbons with 20 S03 solution in C2H4CL2 at a 115 hydrocarbon S03 mole ratio 11.5, and neutralizing the sulfonic acids with CAOH2.
