Verfahren zur Herstellung von Aldehyden und Alkoholen

摘要

A process for preparing aldehydes which comprises reacting an olefinic unsaturated compound with hydrogen and carbon monoxide by hydroformylation reaction in the presence of a catalyst in a continuous multistage flow reactor, wherein the continuous multistage flow reactor contains n number (n>/=2) of flow reactors, and the reaction is carried out in the presence of pressure sectional zones satisfying at least one of the following pressure conditions (1) to (3), provided that partial pressures of hydrogen and carbon monoxide in each reactor are illustrated as (PH2(1),PCO(1)), (PH2(2),PCO(2)), ... (PH2(n),PCO(n)) in order from the upper stream from the reactor, $in\; which\; m\; is\; an\; integer\; in\; the\; range\; of\; 2$
