    摘要: A continuous process for hydroformylating butene-2 so as to produce 2-methylbutanal in the presence of an halogen-free rhodium complex catalyst of the formula RhH.sub.m (CO).sub.n L.sub.p, wherein "L" is a trialkyl (including cycloalkyl) phosphine ligand having a cone angle within the range of 159 to 171 degrees and wherein the frequency of the A.sub.1 carbonyl mode of the Ni(CO).sub.3 L in dichloromethane is within the range of 2056.1 to 2061.1 cm.sup.-1, there being no substantial excess of free phosphorous ligand.
