    Abstract: The invention relates to a process for the preparation of methyl formate by reacting methanol with carbon monoxide at a pressure of from 0.5 to 10 MPa abs. and a temperature of from 50 to 150° C. in the presence of a metal alkoxide as catalyst in a reactor, in which a gas stream is withdrawn from the reactor, entrained methyl formate is removed from this gas stream by condensation, and all or some of the remaining gas stream is returned to the reactor as circulating-gas stream and a mean gas superficial velocity of from 1 to 20 cm/s is set in at least one region of the reactor in which the gas flows essentially in one direction.

    Abstract: The invention relates to a method for the carbonylation of n-pentenoic acid or derivatives thereof of formula (I), wherein R represents CN or COOR and R represents hydrogen, alkyl or aryl. According to said method, a compound of formula (I) is reacted with carbon monoxide and a compound (II) containing a hydroxyl group in the presence of a catalyst system. The method is characterised in that the catalyst system is obtained by reacting a) a source of a metallic ion of a metal (III) of the 8 subgroup of the periodic table with b) a bidentate phosphine ligand of formula (IV), wherein R , R , R , R , R , R , R , R , R , R , R and R independently of one another represent an inorganic group, which contains a respective carbon atom, by means of which the respective group is linked to the relevant tertiary carbon atom given in formula (IV), L , L represent independently of one another a lower alkylene group and X represents an arylene group.

    Abstract: Aldehydes are produced by reaction of at least one compound having a vinyl- or vinylidene group with carbon monoxide and water in the presence of a source of Group VIII metals and a divalent diphosphine ligand whereby the molar ratio of ligand to metal is at least 5. Aldehydes (I) are produced by reaction of at least one compound having a vinyl- or vinylidene group with carbon monoxide and water in the presence of a source of Group VIII metals and a divalent diphosphine ligand of formula (1) whereby the molar ratio of ligand to metal is at least 5. A = together with the phosphorous atom it is bonded to comprises a 2-phospha-tricyclo(3.3.1.1(3,7)) decyl group, optionally having non-neighboring carbon atoms substituted by oxygen atoms and optionally substituted; X = 1-10 atom containing bridging chain.
