    Abstract: The invention relates to a method for the continuous production of a compoun d that carries at least two functional groups, independently selected from the group consisting of nitrile group, carboxylic acid group, carbonic ester group, carbonic amide group. The inventive method comprises the following steps: a) adding two terminal olefins that carry the functional groups required for the production of the compound according to a1) carrying at lea st two functional groups, in the presence of a compound according to a3) that i s suitable as a catalyst for said addition and that is homogenous with respect to the reaction mixture, thereby obtaining a mixture that contains a1) a compound obtained by simple addition of the two above-mentioned terminal olefins that carry at least two functional groups, independently selected fr om the group consisting of nitrile group, carboxylic acid group, carbonic ester group, carbonic amide group, a2) a compound obtained by multiple addition of the above-mentioned two terminal olefins, and a3) the compound that is suitable as a catalyst for said addition and that is homogenous with respect to the reaction mixture, b) distilling the mixture obtained in step a) while obtaining b1) the compound obtained by simple addition of the two above- mentioned terminal olefinsthat carry at least two functional groups, independently selected from the group consisting of nitrile group, carboxyli c acid group, carbonic ester group, carbonic amide group, as the overhead product, and b2) a mixture containing b2a) a compound obtained by simple addition of the two above-mentioned terminal olefins that carry at least two functional groups, independently selected from the group consisting of nitri le group, carboxylic acid group, carbonic ester group, carbonic amide group, b2 b) a compound obtained by multiple addition of the above-mentioned two terminal olefins, and b2c) the compound that is suitable as a catalyst for said addition and that is homogenous with respect to the reaction mixture, c) separating the entire mixture obtained in step b2) or a part thereof by mean s of a semipermeable membrane while obtaining a permeate and a retentate in su ch a manner that the weight ratio of component b2b) to component b2c) of the mixture added in step c) is smaller than in the retentate, d) returning, either partially or completely, to step a) the permeate obtained in step c), and e) returning, either partially or completely, to step a) the part of the mixture obtained in step b2) and not separated according to step c).

    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.
