Abstract
Olefin compositions comprising Cto Cbranched chain olefins are stabilised by the addition of 5 to less than 50 ppm by weight of antioxidant. These lower than normal amounts of antioxidant enable improved yields in a hydroformylation reaction using the olefin composition as feedstock and in esterification reactions employing the alcohol produced in the hydroformylation reaction. Consistent lower levels of antioxidant can be achieved by use of a liquid antioxidant and a pump driven dosing system.
