FUEL COMPOSITION OF DIESEL FUEL Russian patent published in 2023 - IPC C10L1/08 C10L1/18 C10L1/185 C10L1/188 

FIELD: diesel fuel composition.

SUBSTANCE: proposed fuel composition based on diesel fraction, boiling in the range of 180-360°C, containing organic peroxides from the group of peroxyketals of general formula (1) as ignition promoters, where R₁ and R₂ are 2-phenylisopropyl or tert-butyl radical, R₃ = R ₄ is a methyl radical; selected from the following group: 2,2-di(2-phenylisopropylperoxy)propane, 2,2-di(t-butylperoxy)propane; or a mixture of cyclic derivatives obtained from two and three ketone molecules - formula (2), where R₁ and R₂, R₃ and R₄ in pairs form cyclohexene substituted with three methyl groups, or R₁ and R₃ are isobutene-2-yl radical, and R₂ and R₄ is a methyl radical, or R₁ = R₃ is 2-hydroxy-2-methylpropyl radical, and R₂ = R₄ is a methyl radical; and formula (3), where R₁ and R₂, R₃ and R₄, R₅ and R₆ in pairs form cyclohexene substituted with three methyl groups, or R₁ = R₃ = R₅ is an isobuten-2-yl radical, and R₂ = R₄ = R₆ is a methyl radical, or R₁ = R₃ = R₅ is a 2-hydroxy-2-methylpropyl radical, and R₂ = R₄ = R₆ is a methyl radical; moreover, mixtures of cyclic derivatives obtained from two and three ketone molecules, formulas (2) and (3) are selected from the following group: 3,6,9-tris(2,4,4-trimethylcyclohexene-1)spiro-1,4,7-triperoxane and 3,6-bis(2,4,4-trimethylcyclohexene-1)spiro-1,4- diperoxane; 3,6,9-triisobuten-2-yl-3,6,9-trimethyl-1,4,7-triperoxane and 3,6-diisobuten-2-yl-3,6-dimethyl-1,4-diperoxane; 3,6,9-tri(2-hydroxy-2-methylpropyl-1)-3,6,9-trimethyl-1,4,7-triperoxane and 3,6-di-(2-hydroxy-2-methylpropyl- 1)-3,6-dimethyl-1,4-diperoxane; at the following ratio of components, in % by weight: peroxyketal 0.01-0.5, diesel fraction - up to 100.

EFFECT: obtaining a fuel composition of low-sulphur diesel fuel that meets the requirements of GOST 32511, GOST R 52368, EN 590, GOST R 55475, TR CU 013/2011, as well as expanding the arsenal of using organic peroxides as ignition promoters.
