ADDITIVE COMPOSITION FREE OF POLYCYCLIC CARBOXYLIC ACIDS AND ACID DERIVATIVES THEREOF, FUEL OIL COMPOSITION AND USES THEREOF

摘要

PURPOSE: To prevent soluble components from falling out of a solution resulting in separation of an additive and poor fuel filterability by not employing polycyclic acids or their derivatives and controlling the percentage by mass of unsaturated acids including polyunsaturated acids, and of saturated acids in an additive. CONSTITUTION: The additive composition comprises an additive (a), comprising a plurality of monocarboxylic acids, each having from 10 to 24 carbon atoms, or acid derivatives thereof, less than 7 mass% of which acids or acids from which the derivatives are derived having a linear chain and being saturated, and the balance being unsaturated, at least 35 mass% of which balance being polyunsaturated.
