| Abstract: | Benzyl chloride was converted to phenylacetic acid by carbonylation in the presence of Co2(CO)8 using two kinds of waste gas which contains above 85% carbon monoxide. When the reaction was carried out at 55℃ and atmospheric pressure for 4. 5h,the yield of phenylacetic acid was 90%, purity was 99.9%,The recoveries of this system s solvent and catalyst were also studied. It was found that the rate of recovery of catalyst was over 90%. |
