  • Cyclopropane-containing compounds useful as fuel
    Patent number: 12680114
    Abstract: The present invention provides for a cyclopropane compound having the following chemical formula: wherein ? is —H or —COOR, wherein R is —H or an alkyl group, such as —CH3, —CH2CH3, —(CH2)2—CH3, —(CH2)3—CH3, or —C(CH3)3; ? is each independently wherein at least one ? is and, n is an integer from 3 to 11. A fuel composition comprising the cyclopropane compound thereof and a fuel additive. The present invention also provides for a system or genetically modified host cell capable of producing the cyclopropane compound, and a method for producing the cyclopropane compound.
