| Abstract: | 3, 4, 5-trimethoxybenzaldehyde was synthesized by means of methylating, hydrolysis, esterification hydrazinolysis and oxidation from Tara powder as raw material. The structure was confirmed to be identical with that of 3, 4, 5-trimethoxybenzaldehyde synthesized from gallic acid by means of MS and IR spectra. The cost decreased by fifteen thousands yuan. |
