Abstract

InterLn=1413;>(57) A találmány tárgya olyan üzemanyag, amelyet azüzemanyagban jelenlévő gyűrűs keton-peroxidok összes mennyiségérevonatkoztatva 0,01-10 tömeg% mennyiségben (I) általános képletű gyűrűsketon-peroxiddal adalékolnak. A találmány szerinti gyűrűs keton-peroxidok szerkezetét az (I) általános képlet fejezi ki, ahol az R1-től R6-ig terjedő csoportok egymástól független jelentése 1-20szénatomos alkil-, 3-20 szénatomos cikloalkil-, 6-20 szénatomos aril-,7-20 szénatomos aralkil- vagy 7-20 szénatomos alkarilcsoport, amelycsoportok lineáris vagy elágazó szénláncú csoportok lehetnek; és R1-R6csoportok mindegyike adott esetben egy vagy több hidroxil-, alkoxi-,egyenes vagy elágazó alkil-, ariloxi-, észter-, karboxil-, nitril-vagy amidocsoporttal adott esetben szubsztituálva lehet, azzal amegkötéssel, hogy ezek a peroxidok az üzemanyagban jelenlévő összesperoxidok tömegére vonatkoztatva legalább 35 tömeg% mennyiségbenvannak jelen. A találmány szerinti hajtóanyag belső égésű motorbanalkalmazva a szennyezőanyagok kibocsátását csökkenti. A találmány afenti üzemanyagok előállítási eljárására is vonatkozik. ÓInterLn=1413;>(57) The subject of the invention is a fuel that is added with ring ketone peroxide of general formula (I) in an amount of 0.01-10% by weight, based on the total amount of ring ketone peroxides present in the fuel. The structure of the cyclic ketone peroxides according to the invention is expressed by the general formula (I), where the groups from R1 to R6 independently mean alkyl with 1-20 carbon atoms, cycloalkyl with 3-20 carbon atoms, aryl with 6-20 carbon atoms, C7-20 aralkyl or C7-20 alkaryl group, which groups can be linear or branched carbon chain groups; and R1-R6 groups can optionally be substituted with one or more hydroxyl, alkoxy, straight or branched alkyl, aryloxy, ester, carboxyl, nitrile or amido groups, with the stipulation that these peroxides present in the fuel they are present in an amount of at least 35% by weight based on the weight of total peroxides. When used in an internal combustion engine, the propellant according to the invention reduces the emission of pollutants. The invention also applies to the production process of afent fuels. HE
