摘要：

Hydroformylation of short chain internal olefins to linear aldehydes is an interesting subject due to the enormous importance of the resulting oxo products. Here we report a systematic study of the hydroformylation of 2-pentenes in an aqueous two-phase system with a Co/TPPTS catalyst. At elevated, temperatures and pressures good yields of the desired aldehydes were obtained. Linear to branched ratios (n/iso) of up to 70:30 were observed. Recycling of the catalyst and reuse up to four times without loss of activity has been demonstrated. (C) 1999 Elsevier Science B.V. All rights reserved.
