摘要
The invention relates to a low-soot diesel fuel comprising a fuel additive, to the uses thereof and to the use of the fuel additive for producing low-soot diesel fuels. The diesel fuels are mineral-based, optionally with additions of FAME or XTL diesel fuels, which are formulated with polyoxaalkanes of the general formula (I):; R1(—O—CH2—CHR2)m—O—R3 (I);In the formula (I), the R1 radicals are each a straight-chain or branched alkyl radical, R2 is a straight-chain or branched alkyl radical or H, and R3 is likewise a straight-chain or branched alkyl radical. In addition, m is ≧1, and the fuel additive is essentially free of toxic constituents. Diesel fuels formulated in this way, even at a low polyoxaalkane content, have significantly reduced soot formation. The proportion of premixed combustion and the density are increased, and the volumetric reduction in calorific values which occurs when CH2 groups in long-chain alkanes are replaced by O groups can be compensated for. The invention further relates to a process for homogenizing diesel fuel/alkanol mixtures, in which addition of the polyoxaalkanes described affords a monophasic diesel fuel. Such mixtures are of interest with regard to falling crude oil reserves, because primary alcohols such as ethanol can be prepared readily and inexpensively from organic starting materials.
