  Aldehydes are produced by unmodified rhodium catalyzed hydroformylation process in a homogeneous organic phase using a solution of unmodified rhodium catalyst and an organic acid in a total amount, calculated as acid equivalent, of from greater than 3 moles to 3000 moles of acid per mole of rhodium. The organic acid is selected from: saturated aliphatic monocarboxylic acids having from 5 to 13 carbon atoms in the molecule; saturated aliphatic dicarboxylic acids having from 5 to 13 carbon atoms in the molecule; sulphonic acids having from 1 to 12 carbon atoms in the molecule; and combinations thereof. Use of the process can lead to either a significant increase in conversion without reducing selectivity for the desired aldehyde or a reduction in the specific use of rhodium.

  醛类化合物是通过未改性的铑催化水合甲酰化过程在均相有机相中产生的，使用未改性铑催化剂和有机酸的溶液，总量以酸当量计算，每摩尔铑大于3摩尔至3000摩尔的酸。所选的有机酸包括：分子中含有5至13个碳原子的饱和脂肪族一元羧酸；分子中含有5至13个碳原子的饱和脂肪族二元羧酸；分子中含有1至12个碳原子的磺酸；以及它们的组合。使用该过程可以导致转化率显著增加，而不降低对所需醛的选择性，或者减少铑的特定使用。
