Thermally stable distillate fuels

Claim 1

A FUEL OIL COMPOSITION COMPRISING A MAJOR AMOUNT OF A DISTILLED HYDROCARBON FUEL OIL SELECTED FROM THE CLASS CONSISTING OF FURNACE OILS, DIESEL FUELS, AND JET ENGINE FUELS AND A MINOR AMOUNT, SUFFICIENT TO STABILIZE THE FUEL AGAINST THE FORMATION OF SLUDGE AND UNDESIRABLE COLOR BODIES, OF THE FUEL OIL-SOLUBLE PRODUCT OBTAINED BY THE OXYALKYLATION OF MONOMERIC POLYAMINO COMPOUNDS; SAID OXYALKYLATION BEING ACCOMPLISHED BY THE USE OF A MONOEPOXIDE HAVING NOT OVER 18 CARBON AND FREE FROM OTHER FUNCTIONAL GROUPS. (A) THE INITIAL POLYAMINO REACTANT BEING COMPOSED EXCLUSIVELY OF CARBON, HYDROGEN, OXYGEN, AND NITROGEN ATOMS AND CONTAINING 2 TO 7 BASIC NITROGEN ATOMS LINKED BY A MEMBER OF THE CLASS CONSISTING OF CARBON ATOM CHAINS HAVING 2 TO 7 CARBON ATOMS AND OXYGENINTERRUPTED CARBON ATOM CHAINS CONTAINING 2 TO 7 CARBON ATOMS; (B) THE INITIAL POLYAMINO REACTANT HAVING A MOLECULAR WEIGHT OF 60 TO 275 AND A PLURALITY OF REACTIVE HYDROGEN ATOMS; (C) THE INITIAL POLYAMINO REACTANT BEING WATER SOLUBLE; (D) THE OXYALKYLATION END PRODUCT BEING WATER INSOLUBLE; (E) THE OXYALKYLATION END PRODUCT BEING WITHIN THE MOLECULAR WEIGHT RANGE OF 300 TO 8500 ON AN AVERAGE STATISTICAL BASIS; (F) THE SOLUBILITY CHARACTERISTICS OF THE OXYALKYLATION END PRODUCT IN RESPECT TO WATER AND FUEL OIL BEING SUBSTANTIALLY THE RESULT OF THE OXYALKYLATION STEP; (G) THE MOLAL RATIO OF ALKYLENE OXIDES PER INITIAL REACTIVE HYDROGEN ATOM BEING WITHIN THE RANGE OF 1 TO 45:1; (H) THE INITIAL POLYAMINO REACTANT REPRESENTING UP TO 20% BY WEIGHT OF THE OXYALKYLATION END PRODUCT ON A STATISTICAL BASIS; (I) THE PRECEDING BEING BASED ON THE ASSUMPTION OF COMPLETE REACTION INVOLVING THE ALKYLENE OXIDES AND INITIAL POLYAMINO REACTANT.
