    Abstract: Polyalkene alcohol polyalkoxylates R-(CH2)n-(O-A)m-OH, where R is a polyalkene radical derived from C2- to C30-alkenes and having a number average molecular weight from 300 to 5000, A is an alkylene group of 2 to 8 carbon atoms, m is a number up to 200, with the proviso that the oxygen in the oxyalkylate radical accounts for at least 16.5% by weight of the number average molecular weight of the total molecule I, and n is 0 or 1, are suitable as carrier oils in fuel and lubricant compositions.

    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: A process for the preparation of aldehydes or aldehydes and alcohols by hydroformylation of olefins containing more than 3 carbon atoms, comprising a hydroformylation stage, in which the olefin is hydroformylated under a pressure of form 50 to 1000 bar and at a temperature of from 50° to 180° C. by means of a rhodium catalyst dissolved in a homogenous reaction medium and a catalyst recovery stage comprising extraction of the rhodium catalyst with an aqueous solution of chelating agent, isolation of alcohols and/or aldehyde from the extracted hydroformylation product steam, precarbonylation of the aqueous rhodium-containing extract in the presence of carbon monoxide, synthesis gas as, or a gas mixture containing carbon monoxide under a pressure of from 50 to 1000 bar and at a temperature of from 50° to 180° C., separation of the effluent of the precarbonylation stage into an organic phase containing the major portion of the rhodium and an aqueous phase containing the chelating agent and recycling of the organic phase to the hydroformylation stage, where the rhodium catalyst is extracted from the effluent of the hydroformylation stage using an aqueous solution of a sulfonic acid group-free, water-soluble polymer capable of chelating rhodium.
