Claims4
Process for the preparation of cyclopropylmethanol which comprises hydrogenating cyclopropanecarboxaldehyde with hydrogen in the presence of a cobalt or nickel hydrogenation catalyst under hydrogenation conditions of pressure and temperature.
Process for the preparation of cyclopropylmethanol which comprises hydrogenating cyclopropanecarboxaldehyde with hydrogen in the presence of a hydrogenation catalyst selected from Raney cobalt, Raney nickel and supported nickel catalysts comprising 40 to 60 weight percent nickel on an alumina support at a pressure of about 3 to 8 bar absolute and a temperature of about 20.degree. to 80.degree. C.
Process for the preparation of cyclopropylmethanol which comprises hydrogenating cyclopropanecarboxaldehyde with hydrogen at a temperature of about 20.degree. to 50.degree. C. and a pressure of about 2.4 to 5.2 bar absolute in the presence of a hydrogenation catalyst selected from Raney cobalt, Raney nickel and supported nickel catalysts comprising 40 to 60 weight percent nickel on an alumina support.
