摘　　要：Trimethoxybenzaldehyde (TMB) was hydrogenated over Pd/C in H 2-AcOH,in H 2-MeOH and in NH 2NH 2-PhMe system respectively.In Pd/C-TMB-H 2-AcOH system,TMB was reduced into 3,4,5-trimethoxytoluene (TMT) via 3,4,5-trimethoxybenzyl acetate and (1′-hydroxy)ethyl (3,4,5-trimethoxy)benzyl ether.In Pd/C-TMB-H 2-MeOH system,TMB was reduced into TMT via 3,4,5-trimethoxybenzyl alcohol,methyl(3,4,5-trimethoxy)benzyl ether and bis(3,4,5-trimethoxy)benzyl ether.In Pd/C-TMB-NH 2NH 2-PhMe system,TMB was reduced into TMT directly with mild manner and higher selectivity.Trimethoxybenzaldehyde (TMB) was hydrogenated over Pd/C in H 2-AcOH,in H 2-MeOH and in NH 2NH 2-PhMe system respectively.In Pd/C-TMB-H 2-AcOH system,TMB was reduced into 3,4,5-trimethoxytoluene (TMT) via 3,4,5-trimethoxybenzyl acetate and (1′-hydroxy)ethyl (3,4,5-trimethoxy)benzyl ether.In Pd/C-TMB-H 2-MeOH system,TMB was reduced into TMT via 3,4,5-trimethoxybenzyl alcohol,methyl(3,4,5-trimethoxy)benzyl ether and bis(3,4,5-trimethoxy)benzyl ether.In Pd/C-TMB-NH 2NH 2-PhMe system,TMB was reduced into TMT directly with mild manner and higher selectivity.
