Fuels

Abstract

The invention concerns a fuel comprising a mixture of (A) at least one alcohol with an average molecular weight of less than 160, and (B) at least one further organic compound which has a spontaneous ignition temperature of less than 450.degree. C. The further organic compound is (1) a compound which contains one or more oxygen atoms but no nitrogen atoms, with the proviso that, (1.1) the compound is not a dialkoxy compound of formula ##STR1## in which R.sub.1 and R.sub.2 indicate hydrogen or straight-chain or branched alkyl radicals with up to 4 C-atoms, and R.sub.3 and R.sub.4 are straight-chain or branched alkyl radicals with up to 4 C-atoms; or (2) a compound which contains one or more nitrate groups and one or more ether linkages, or (3) a nitrogen-containing organic compound selected from the group consisting of azo compounds, tetrazines, nitroso compounds, nitro compounds, nitrates, and hyponitrites, with the proviso that component (B) is not entirely a linear or branched-chain alkyl nitrate containing between 2 and 8 carbon atoms. There are the provisos that, when the alcohol is methanol, the component (B) is not (a) a polyether of the general formula R[O(A).sub.n H]m wherein R represents hydrogen or a residue of an organic compound, which is built up of hydrogen and carbon and optionally oxygen and which has from 1 to 12 hydrogen atoms, which can be reacted with ethylene oxide or propylene oxide; A represents independently of each other a group derived from ethylene oxide or propylene oxide; m is a number from 1-12, and n has such a value that the total number of units derived from ethylene oxide and/or propylene oxide is 4-400, and is not (b) a polyether soluble in methanol and which contains 4-400 oxyalkylene units, derived from ethylene oxide and/or propylene oxide, wherein said oxyalkylene units constitute at least 40 percent by weight of the polyether.
