Definitions

• the invention relates to a solubilizer for gasoline fuels, consisting of a mixture of gasoline, alcohol and water.
• the mixture has so far been uneconomical because alcohol could only be used in a largely anhydrous form as a component of the mixture and the distillation effort for obtaining such anhydrous alcohol is unusually high.
• ethanol is obtained from organic matter and usually has a water content of between about 5 and 10% by volume. This also as "bio-alcohol” be drawn ethanol cannot be mixed with petrol due to its water content. When mixed, the water precipitates (2-phase formation) and not only leads to corrosion damage in the engine, but ultimately prevents gasification of the fuel.
• the invention has for its object to provide a solubilizer for gasoline fuels that enables the production of a single-phase mixture of gasoline and water-based alcohol, especially bio-alcohol.
• a mixture additive consisting of a content of about 5 to 40% by volume of a substance from the group of the C 4 and C 5 methyl ketones and 20 to 60% by volume of a substance from the group the C 3 - to C 5 -, preferably C 4 -alcohols and 20 - 40 vol.% of a glycol.
• Methyl isobutyl ketone is preferred as a substance from the group of the C 4 and C 5 methyl ketones and N-butyl alcohol as substance from the group of the C 3 to C 5 alcohols and ethylene glycol as the glycol.
• a nonionic emulsifier with a saponification number in the range from 60 to 75, an iodine number in the range from 25 to 40, a hydroxyl number in the range from 140 to 165 and an HLB value of 8. 1, and in addition an additional 4-9% of a V ol broughttemulgierenden glycerol mono-dioleats with a saponification value of 162-175, an iodine number of 72-82, an HLB value of 3.3.
• a solubilizer has been found to be particularly effective which contains 26.1% by volume of methyl isobutyl ketone, 36.0% by volume of N-butyl alcohol, 27.9% by volume of ethylene glycol, 5.6% by volume of a nonionic emulsifier and 4.4% by volume % contains non-self-emulsifying glycerol mono-dioleate.
• additive composition 40% n-butanol 30% methyl isobutyl ketone 30% ethylene glycol
• additive composition 70% n-butanol 20% methyl isobutyl ketone 5.6% BTO 4.4% Tegin 0
• additive composition 4 0 % n-propanol 30% methyl isobutyl ketone 30% ethylene glycol
