Abstract (en)

Use of one or more 1,1-dialkoxyalkane compound (I) for increasing the antiknock properties of gasoline with a boiling point of 75-120[deg] C without adding further antiknock compounds, is claimed. Use of one or more 1,1-dialkoxyalkane compound of formula (R 1>O-CH(R 2>)-OR 1>) (I) for increasing the antiknock properties of gasoline with a boiling point of 75-120[deg] C without adding further antiknock compounds, is claimed. R 1> : CH 3, C 2H 5, C 3H 7, iso-C 3H 7(all preferred), C 4H 9or iso-C 4H 9; and R 2> : H, CH 3(both preferred), C 2H 5, C 3H 7or iso-C 3H 7. An independent claim is included for a motor gasoline comprising the low-boiling gasoline, (I) and additives, where 1-4C-alcohol or ketal compounds of formula (R3aO-C(R1a)(R2a)-O-R4a) are excluded. R1a : CH 3, C 2H 5or C 3H 7; R2a : CH 3or C 2H 5; and R3a, R4a : CH 3, C 2H 5, C 3H 7or C 4H 9.
