  • Additives for improving autoignition reactivity of hydrocarbon-based fuels
    Patent number: 11814595
    Abstract: According to various aspects, an additive for a hydrocarbon-based fuel has a formula (I), in which R1, R2, and R3 are each independently selected from —H, —CH3, or —CH2CH3, and at least one of R1, R2, or R3 is not —H. The additive improves an autoignition reactivity of the hydrocarbon-based fuel.
