Abstract
1,255,537. Phenylpropanals. RUHRCHEMIE A.G: 27 June, 1969 [24 July, 1968], No. 30083/69. Heading C2C. Phenylpropanals are obtained by hydroformylating styrene with CO and H 2 at 80- 200‹ C. and 50-500 atmospheres pressure in the presence of a rhodium catalyst containing 0À05-0À000125% by weight of rhodium based on the styrene. The phenylpropanals can be hydrogenated to phenylpropanols, either with CO and H 2 without the separation of the rhodium catalyst or the addition of another catalyst, or in the presence of a copper chromite catalyst.
