  • Oxazolidines derived from polyalkyl or polyalkenyl n-hydroxyalkyl succinimides, obtainment process and use
    Patent number: 9981958
    Abstract: Oxazolidines, a process for producing the oxazolidines, and use as additives for fuels to prevent and control deposits in internal combustion engines are disclosed. The oxazolidines are derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides and have the structural formula wherein: R is a polyakyl or polyalkenyl group having an average molecular weight ranging from 450 to 5000 daltons; m is an integer between 1 and 5; n is an integer between 0 and 1; and R1, R2, R3, and R4 are independent radicals, represented by the groups: —H, —CH2(CH2)AB, —C6H3DE or —C10H4FG; wherein: A is an integer between 0 and 8, B is a group selected among —H, —NH2, —OH, —COOH, and D, E, F, and G are independent radicals, selected among the groups: —H, —CH3, —CH2CH3, —CH2CH2CH3, —CH2(CH2)2CH3, —(CH3)3, C6H5, —NH2, —OH, —OCH3, OCH2CH2OH, OCH(CH3)CH2OH, OC6H5—COOH, and —SO3.

  • Asphaltene-dispersing/inhibiting additive based on oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides
    Patent number: 9221803
    Abstract: The present invention relates to formulations of asphaltenes' inhibitor-dispersant additives based on oxazolidine derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides. Said formulations can contain inert organic solvents, preferably including: toluene, mixtures of xylene, o-xylene, p-xylene, kerosene, turbo-fuel; or inert hydrocarbon solvents having boiling points within the range of gasoline and diesel; or inert hydrocarbon or organic solvents having a boiling point within a range from 75 to 300° C. The ratio in weight of inert organic solvents to additive that prevents and controls the precipitation and deposition of asphaltenes ranges from 1:9 to 9:1, preferably from 1:3 to 3:1.
