Cetyltrimethyl ammoniumbromide

In a series of studies performed by different groups hydroformylation of higher alkenes in microemulsions resulted in high turn-over frequencies (TOFs) of up to 5000 per hour for 1 -octene [46] and 1000 per hour for 1-decene [44]. Cationic surfactants such as cetyltrimethyl ammoniumbromide (CTAB) were used in the first studies of hydroformylation of various alkenes with the Rh-TPPTS catalyst. Both high activity and selectivity were observed in the hydroformylation of 1-octene and 1-decene using a sulphonated bisphosphine modified rhodium complex in the presence of ionic surfactants or methanol.
