Abstract: Sodium tetracarbonyl cobaltate was prepared by reaction of CO with CoCl2 inCH3OH, using Urushibara-Cobalt (U-Co) as activator and characterized by IR spectrometry-The optimum conditions were: Co(from U-Co)/CoCl2=0.6; 30 ℃; 0.1 MPa of CO.Theconvertion of CoCl2 in 3h of reaction was 96%.The convertion of benzyl chloride to pheny-lacetic acid using the Na[Co(CO)4] as catalyst was about 90% at 50℃ and 0.1 MPa of CO.

Key words: sodium tetracarbonyl cobaltate, urushibara-cobalt, phenylacetic acid, synthesis
