Abstract

An anti-knock mixture for motor fuel comprises a lead anti-knock compound and one or more bromo-hydrocarbons having 2-3 bromine atoms and 3-8 carbon atoms, not more than one bromine atom attached to any carbon atom, and a vapour pressure at 50 DEG C of 0.2-6mm. of mercury. Bromo-hydrocarbons referred to are 1, 3, 4-tribromopentane, 4, 5-dibromo 1, 3-dimethylbenzene, 1, 2, 5-tribromopentene-1, 1, 2, 3-tribromopentane, dibromotoluenes, 1, 2, 3-tribromobutane, 6, - bromo-4-(bromomethyl)-heptane-1, 1, 2-dibromocyclohexane, 1, 2, 3-tribromo-2-methyl-propane, 1, 2, 3-tribromopropane, 1, 2-dibromo-benzene, 2, 5-dibromopentene-1, 1, 2-dibromohexene-1, 1, 3-dibromo-2, 2-dimethylpropane, 1, 6-dibromohexane, and the various dibromobutanes and dibromopentanes. The mixture may also contain a p chlorohydrocarbon having a vapour pressure at 50 DEG C of 0.2-6mm. of mercury; those referred to are 1-chloronaphthalene, (5-chloroamyl-) benzene, 1-chlorohendecane, 1, 2, 3, 4-tetrachlorocyclopentane, hexachloropropylene, 1, 2, 4-trichlorobenzene, 2, 4-dichlorotoluene, 1, 2-dichlorocyclohexane, 1-chlorooctane, 5-chloro-2, 2, 3-trimethylhexane, 1, 3-dichloro-2, 2-dimethyl propane, 1, 2-dichloroheptane, 1, 8-dichlorooctane, 5, 6-dichloro-3, 3-dimethyl hexane, and the various dichlorobutanes and dichloropentanes. Anti-knock compounds mentioned are tetraethyl lead, tetrapropyl lead, dimethyldiethyl lead, and methyl triethyl lead. Specifications 224,102, 245,281 [both in Class 91] and U.S.A. Specifications 2,361,337 and 2,398,281 are referred to.
