| Abstract: | Selective hydrogenation of benzoic acid to benzaldelyde free of chloride by Mn catalyst is studied.Under the optimum reaction conditions,the conversion of benzoic acid is over 98%,the selectivity of benzaldehyde is over 85%,and the yield of benzaldehyde is more than 85%.Gas phase hydrogenation technology is used in the process.The products are easily separated,and the quality of the product is good.The process has a bright prospect for industrialization. |
