실험 절차

400 g of 3-methyl-2-pentene as well as 40 mg Rh (in the form of 2-ethylhexanoate) were introduced into a high pressure vessel (volume 2.1 liters) and were reacted with an equimolar mixture of carbon monoxide and hydrogen at 90° C. and 260-270 bar. The reaction was completed in 7 hours, after which the pressure was relieved and the reactor allowed to cool. The composition of the crude reaction product was determined by a vacuum distillation and a gas chromatographic analysis. With a 99.9% 3-methyl-2-pentene conversion, 81.3% of isomeric C7 aldehydes was obtained as 2,3-dimethylpentanal (cf. Table 1, Exp. 1).
