Popis: | 1. On being heated to 180°C, ASK additive is unchanged in its physicochemical and operational properties, as determined by laboratory methods; the detergent and antioxidant properties of the additive are retained up to 300°C. 2. Alkylsalicylic acids are less stable towards high temperatures than the calcium salts. They are thermally stable up to 165°C and are virtually completely decomposed at 240°C. |
