Date Aug. 17, 1995Carboxylic esters of the formula IR1-CO-O-R2 I,where R1 is an aliphatic, straight-chain or branched hydrocarbon radical having alkyl side chains and a number average molecular weight of from 250 to 5000 and R2 is a straight-chain or branched hydrocarbon radical of 1 to 30 carbon atoms or a radical of the formula II II where R3, R4, R5 and R6, independently of one another, are each hyrogen, branched or straight-chain alkyl, an aromatic radical or an araliphatic radical which may also contain heteroatoms, R7 and R8, independently of one another, are each branched or straight-chain alkyl or an aromatic or araliphatic radical which may also contain heteroatoms, X is O, S, NR9 or PR9, where R9 is an aliphatic or aromatic radical, n and m, independently of one another, are each from 2 to 20, and x is from 0 to 30, are used as fuel additives or lubricant additives, and fuel compositions or lubricant compositions contain these additives. Carboxylic acids or carboxylic esters are prepared by reacting polymers having at least 30 carbon atoms and at least one carbon-carbon double bond with carbon monoxide and water or an alcohol.

    Abstract: PCT No. PCT/EP96/01123 Sec. 371 Date Sep. 16, 1997 Sec. 102(e) Date Sep. 16, 1997 PCT Filed Mar. 15, 1996 PCT Pub. No. WO96/29300 PCT Pub. Date Sep. 26, 19963-Pentenoic esters are prepared by carbonylation of alkoxybutenes in the presence of a catalyst and a solvent at elevated temperature and elevated pressure, by reacting at least one C1-C10-alkoxybutene in which the alkoxy group is in the allyl position relative to the double bond with carbon monoxide at from 60 to 140 DEG C. and a carbon monoxide partial pressure in the range from 3 to 30 MPa in the presence of a catalyst based on palladium.
