| titleOfInvention | Method for preparing aldehyde and acid by electrochemical dechlorination of polychlorinated methyl pyridine derivative |
| abstract | The invention discloses a method for preparing aldehyde and acid by electrochemical dechlorination of polychlorinated methylpyridine derivatives, which comprises the following steps: the polychlorinated pyridine derivative is dissolved inObtaining an electrolytic reaction solution in a buffer solution containing acetic acid-acetate; taking the electrolytic reaction liquid as cathode liquid, carrying out electrolytic reduction dechlorination reaction on the cathode, and hydrolyzing in the solution to obtain polychlorinated pyridine aldehyde or acid derivative; the polychlorinated picoline derivative is shown as a formula (I), and the product polychlorinated picolinic aldehyde or acid derivative is shown as a formula (II): in the formula (I), m is 0, 1, 2,3 or 4, n is 0 or 1, and R' is an easily oxidized or easily substituted group; in the formula (II), m and R' are the same as those in the formula (I), R is H or OH, no waste acid is generated in the preparation process, easily-oxidized or easily-hydrolyzed substituent groups contained in the polychlorinated methyl pyridine derivative and carbon-chlorine bonds on a pyridine ring are not influenced, and the recovery conversion rate is high. |
