    Abstract: Fuel compositions for internal combustion engines, comprising a principle amount of a liquid hydrocarbon fuel and an amount, which has a cleaning effect, of at least one propoxylate additive of the formula I where n is an integer from 10 to 20 and R 1 is straight-chain or branched C 8 -C 18 -alkyl or C 8 -C 18 -alkenyl, if required in combination with at least one detergent additive, e.g. a polyalkylamine additive of the formula II R 2 -NH 2 (II) where R 2 is a straight-chain or branched polyalkyl radical having a number average molecular weight of from about 500 to about 5000, and fuel additive compositions which contain propoxylates of the formula I and, if required, further additives, such as the aforementioned polyalkylamines of the formula II, as intake valve cleaners.

    Abstract: The invention relates to a method for hydroformylating olefins having between 20 and 400 carbon atoms by reacting the olefins with synthesis gas in the presence of a cobalt carbonyl catalyst, by recovering the cobalt catalyst by extracting the discarded substances resulting from the reaction using an aqueous acidic solution in the presence of oxygen, and by separating the organic and aqueous phases. The inventive method is characterized in that: (a) the aqueous phase is separated away from the organic phase to the greatest possible extent by using mass forces such that the proportion of the aqueous phase dispersed in the organic phase is equal to 2 wt. % or less with regard to the organic phase, and; (b) the organic phase involved in step (a) is subjected to an electric field while effecting the coalescence of the dispersed aqueous phase. This enables the residual cobalt content in the hydroformylation product to be reduced to less than 1 ppm.
